On the highway, motorists encounter various troubles and breakdowns, one of which is a broken tire. You can replace it if you have a spare tire, which should always be in the trunk of the car, and a set necessary tools. Doing tire fitting yourself is sometimes more profitable than seeking a similar service at a service station. Help from specialists in this matter often costs a pretty tidy sum, not to mention the seasonal replacement of tires, which is always accompanied by huge queues of drivers who decide to change tires at the last moment. We'll tell you how to do tire fitting yourself in this article.
Signs of a broken wheel
Damage to a car wheel is always accompanied by the following symptoms:
- A sharp decrease in driving speed.
- The appearance of third-party sounds.
- Car skidding and jerking flat areas tracks.
A tire puncture requires the driver to immediately stop the car on the side of the road and check the condition of the tire. If it is damaged, the following actions are taken:
- First gear and parking brake are set. If the car is on a slope, then one wheel is protected by a stop - a stone, a log or a “shoe”.
- Turn on the alarm.
- Put up warning signs.
- Start manual tire fitting with your own hands.
Precautionary measures
Do-it-yourself home tire fitting is mainly carried out in the garage. You can disassemble and bead a tire using special tools - pry bars. Do-it-yourself tire fitting is often done using chisels. You cannot use heavier tools - they can damage the rubber, tube, rims and tires. In addition to the usual tools, you can use a special machine for tire fitting, which you can do yourself.
It is advisable to carry out the procedure for replacing a wheel at a distance from the car, since damage to the body can be caused if the mount is broken. The driver must also take precautions to avoid injury if the tools spring back.
Wheel disassembly
Do-it-yourself tire fitting begins with disassembling the wheel.
- One tire bead is removed from the wheel rim. The edge of the rubber is carefully pryed up with a pry bar and supported with a screwdriver to prevent it from sliding back, after which it is pulled out over the rim. Before starting work, it is advisable to wet the rim with soapy water - this will make the process of removing the rubber easier.
- At a distance of 15-20 cm, a second mount is inserted and moved to the side until complete withdrawal sides.
- The second side of the tire is removed in the same way.
- Remove the stretched rubber by hand.
Installing a new tire
Do-it-yourself tire fitting is carried out after disassembling the wheel as follows:
- One side of the rim is driven overboard.
- A mounting blade is placed between the wheel and the tire, with which part of the bead is inserted over the edge of the wheel.
- At a distance of 10-15 cm, the next section of the tire is inserted behind the edge with the second blade.
- The first blade is installed behind the second and the whole process is done in the same way.
- The second bead of the tire is placed in the rim in a similar way.
- The installed tire must be inflated at the end of the work.
Using raw rubber or a special adhesive patch allows you to repair the tire after you have done the tire fitting yourself. A manual tire changing machine greatly simplifies and speeds up the entire process of changing tires. Tires cannot be repaired if the puncture size exceeds 12 mm.
Tire fitting tools
Do-it-yourself tire fitting can be done using special equipment; it is sold in car dealerships. In addition, you can make the desired machine yourself: there are a large number of drawings on the Internet. Tire fitting equipment is a structure equipped with two levers: one of them is equipped with a pawl and a stopper, and the second is stationary. Pressing the lever allows you to quickly and easily remove the rubber from the wheel rim.
The rubber is removed using a disk with a special gear. It is rotated with a wheel wrench, which allows you to remove the rubber thrown on the disk. To put on the rubber, you need to tuck it under the roller. The entire tire fitting process rarely takes more than 10 minutes.
Creating a tire kit
This kit consists of two parts: a bead beating device and a tire changing machine. The lower frame is made from steel pipe in the form of the letter H with dimensions of 90 x 60 cm. At a distance of 30 cm from the edge, a pipe with a diameter of 2 inches and a length of about one and a half meters is welded to the lintel at a right angle. The weld seam can be reinforced with right-angled triangles. To attach the wheel, an old hub is put on the pipe and welded. Its height is selected so that the wheel placed on it is at the level of a person’s waist. The pipe should rise no more than 30 cm above the cylinder and not interfere with work. At a short distance from the hub, a bracket is welded that will attach the bead breaker device - it is made from steel sheet 4-5 mm thick, in which a hole is drilled for a bolt.
The photo above shows a device for beating the wheel bead. To make it, take a pipe of larger diameter so that a long lever can be inserted into it.
For the lever, a steel pipe one and a half meters long is used, its tip is made of a steel rod with a diameter of 20 mm. The length of the lever can be varied and depends on free space in the garage and hand strength. The tips for the lever are made either using a grinder with a grinding and flap wheel, or using lathe.
The smaller the angle at which the bead tip is welded to the lever, the easier it will be to put the wheel rubber on the rim. However, it should not be made too small. During beading, the lever can scratch the wheel disc, so it is necessary to find the optimal angle.
Since the finished tire changing machine is lightweight, it must be secured to the garage floor. This can be done using self-tapping screws if the floors are wooden, or with anchor bolts installed in the holes and filled with concrete if the garage floor is concrete.
To make work easier and reduce the risk of damage to rubber and rims, the lever tips and tire bead are lubricated with a soap solution. For a similar purpose, all wheels are thoroughly washed and free of dirt before tire fitting.
Adapters with studs allow you to work with wheels that differ from the original ones in the distance and number of holes for fasteners. Such adapters can be made independently from metal one centimeter thick.
It is not difficult to carry out tire fitting yourself, the main thing is to have necessary materials and tools.
The tire replacement procedure is best performed in a specialized workshop. But such an opportunity is not always available. The cost of this service should also be taken into account. Therefore, some car enthusiasts prefer to do the installation and dismantling of tires on their own. For this you need at least the simplest tire service.
Design Features
Tire mounting kit
At first glance, the procedure does not seem very difficult. You just need to dismantle old tire from the disk and install a new one. But already at the stage of removing the tire, you can encounter a problem - too much effort must be made to perform dismantling.
You can use so-called “travel kits” for this. They are supplied with mounts various shapes and special wedges. Such tools make the replacement procedure somewhat easier, but not always. If the tire has been used for a long time— great physical force will be required to separate it from the edge of the disk. That is why the easiest way is to make a homemade tire changing machine.
Its design should consist of the following components:
- Frame. Most often, these are two rectangular profile pipes located parallel to each other. They are connected using a steel angle.
- A vertical riser attached to the frame. It performs several functions - mounting a lever (for removing a tire) and a platform for installation rim. Its function can be performed by a welded flange from the pipe.
- The pipe to which the handle is welded. It will act as a lever when directly removing the tire.
Frame making
Two pipes located parallel to each other are connected using a steel angle or profile design smaller section. Adjustable feet can be installed as optional components.
After making the frame, you should perform the following steps:
- Weld the pipe to the crossbar. Its diameter can be from 20 to 30 mm. The flange is first welded at a height of 40-60 cm.
- On the vertical part is done fastener in the form of a steel plate. It is necessary to install the lever.
The lever is designed to remove the tire from the rim. It consists of two parts - a lever arm (attached to the supporting horizontal post) and a paw, with the help of which forces will be applied to the tire.
After separating the tire from the disk, it must be completely dismantled. To do this, it is best to use a long pry bar to which the handle is welded. Having installed the disk on the flange, it is secured using a clamp. Then, using the narrow end of the mount, the edge of the tire is brought out beyond outer part disk. By turning the disk over, the tire is completely dismantled.
At this stage it is important to pay attention to following points:
- The edge of the rim should not be deformed. This will significantly complicate the subsequent installation of the tire, especially tubeless.
- To maintain the integrity of the tire being removed, you can lubricate the narrow edge with grease. This will reduce the likelihood of cord or rubber breaking.
- When installing a new tire, it is recommended to use a soap solution.
When installing a tire on a rim you need to carefully monitor the absence of gaps between them. In addition to the tire changer, it is recommended to purchase a special set that includes sealing harnesses and pry bars of various sizes.
Every car enthusiast can make his own tire changing machine. All you need is desire and patience. This article will help you build your own machine and teach you some tricks.
Making such a tire changing machine is not that difficult. Unlike others homemade models, this machine is mobile. It's on wheels. After work, you can always move it to a corner. This way it won’t take up extra space.
The design is quite simple. The base is T-shaped, made of two channels 100 mm wide. The length of one channel is 590 mm, and the second 800 mm. They are welded perpendicular to each other.
On top, a pipe with a diameter of 55 mm is welded to the longer channel. The length of the pipe is selected specifically for your height. To make it more convenient for you to work with the machine. IN in this case a pipe 800 mm long is used. Its thickness should not be less than 3 mm, otherwise the pipe will bend. It is also recommended to weld several corners at the base. This will strengthen the structure.
A movable foot is placed on top of the pipe. It moves due to a pipe of larger diameter. Its length is 120 mm. A small channel is welded to this pipe. The main thing is to first carve a recess on it so that it fits around the pipe. Instead of a channel, you can use corners welded together.
A heel is welded to the end of the foot. The heel can be made from a piece of an old disc. In this case, the disk is from a Zhiguli. It is important to weld it in correct location. The heel should protrude from below, that is, it must be welded slightly lower and at an angle. You can weld another small piece of metal on the heel itself, so that it protrudes even lower. This “tooth” will help when working with old, stuck tires.
After putting on the foot, a part is welded to the stand profile pipe. Its wall should not be less than 3 mm. The distance from the welded profile pipe to the lowered foot is 450 mm.
The movable foot and the protrusion from the profiled pipe together represent a mechanism for squeezing the tire.
This concludes our consideration of the lower part of the tire changing machine. Now let's move on to the top part.
The upper part is the bed. It is used to trim the wheels. The bed can be made from the same disk from which the heel was cut. Part of the disk is then welded to a pipe of smaller diameter than the stand. Welding is done from below so that the seam does not interfere. The pipe should be selected so that it does not dangle inside. And for fixation, you can drill holes in the stand and frame pipe, and use bolts as clamps.
For versatility, you can cut recesses in the disk for wheels of larger diameter and gazelle wheels.
The top of the frame is rotatable and removable. It is inserted according to the pipe-in-pipe principle. This device serves as a guide when boarding.
Now let's consider homemade tools, which will help you easily carry out wheel trim work. Let's look at the disassembly tool first.
The handle of this tool is made from a profile pipe or assembled from corners. The tool is tapered towards the end, and at the very tip there is a bearing.
The second tool is for assembling wheels.
The handle for it can also be made from a pipe or corners. Special attention should be given to the tip. The tip is made of several parts. The first part is the tongue, made of cemented tool steel.
To him with reverse side the second part is welded in the form of a pipe cut. Welding must not be done along the entire circumference; the right and upper parts must be free of seams. Otherwise, the tool will tear the rubber. It should also be fixed exactly in the position as shown in the photo.
The review of the machine is over, all that remains is to tell you how it works.
The wheel is placed on the machine and adjusted to the leg. Then a jack is placed on the lowered leg. With its help, pressing the tire from the wheel is easy. Once you have completely pressed the tire away from the rim, you can begin beading.
The wheel is installed on the frame and twisted so that it does not spin. Then, having previously lubricated the tire, the edge is pryed off with a pry bar or a small crowbar.
A beading tool is inserted into the resulting gap and, using a guide, we move it around the circumference of the disk.
The wheel assembly is as follows.
The tire must be generously lubricated. The tongue of the assembly tool must be inserted into the gap between the wheel and the tire. Then, using the lever, move the tool around the circle, while using your other hand to help the tire cling to the side of the rim. If necessary, the tool can be raised.
Having reached the end, the wheel will be ready.

Modern car owners are accustomed to a huge number of tire shops providing their services on virtually every corner. But, unfortunately, developed tire service is typical for large cities, and we have plenty of so-called “bear corners”, where there are no workshops for several kilometers. Of course, in this case, a spare wheel can help out, but it often happens that two wheels are broken at the same time. Therefore, even theoretical knowledge about do-it-yourself tire fitting can be useful to any motorist. More on this later in the article.
- We dismantle the wheel and clean it of dirt.
- Let the air out of the wheel and place it with the nipple facing up.
- We pass the tow rope through the hole in the disk.
- Place the jack on the sidewall of the tire as close to the rim as possible. If the tire has a tube, do not place the jack opposite the fitting, otherwise there is a risk of tearing it off the tube.
- We throw the cable over the bracket or platform for lifting the jack and fix the ends of the cable together.
- We rotate the handle of the end of the jack drive so that it pulls the cable up, and the base moves the seat ring down, resting against the sidewall of the tire.
- As soon as this side of the tire separates from the disk, proceed to the next procedure.
- If you only need to change or repair the tube, then using two mounting tools alternately, we lift the sidewall of the tire near the fitting to the end of the rim.
- Push the fitting in and remove the tube from under the tire.
- We remove the nipple from the working chamber and squeeze out the air from it.
- To install a working tube, bend the sidewall of the tire and insert the fitting from the inside into a special hole designed for it. Then we place the tube under the tire.
- To avoid puncturing the tire tube with a tire iron when installing the tire, slightly inflate it without inserting the nipple.
- After beading, insert the nipple into the fitting, inflate and install the wheel in place.
Tools, fixtures, consumables for making a tire changing machine
- Drill.
- Welding machine.
- Lathe or grinder with grinding and flap wheels.
- Rectangular steel pipe.
- Two inch pipe round section(height 1.5 meters).
- Scarves in the form of right triangles (thickness 5 millimeters).
- Old hub.
- A piece of steel sheet (thickness 4-5 millimeters).
- One and a half meter steel pipe.
- Steel bar (diameter 20 millimeters).
Tire changing machine, how to make it yourself, in detail
In this case, the tire changing machine consists of two tools: a bead beating device and the tire changing machine itself, combined into one.
The bottom of the machine frame, H-shaped, 90×60 centimeters, is made from a rectangular steel pipe.
We weld a two-inch round pipe with a height of about one and a half meters to the jumper at a right angle thirty centimeters from the edge. We reinforce the welding area with gussets in the form of right triangles five millimeters thick. To attach the wheel, we put the old hub on the pipe and weld it to it. We select the mounting height of the hub to suit the person’s height, so that the wheel lying on it is approximately waist-high.
It is necessary that the pipe rises above the cylinder by at least thirty centimeters and does not interfere with work. A little below the hub we weld a bracket for attaching the side trim device. It can be made from a piece of steel sheet four to five millimeters thick by drilling a special hole in it for a bolt.
The structure of the beating tool is clearly visible in the picture. The pipe for making this unit should be taken wider - a long lever should be inserted into it. The lever for mounting and dismantling tires is made of a steel pipe approximately one and a half meters long. The tips for it are made of steel rod, the diameter of which is twenty millimeters.
The length of the lever can be made different, it all depends on the size of the free space in the garage and the strength of your hands. It is advisable to make the lever tips on a lathe, but they can also be cut using a grinder with a grinding wheel, and then sanded with a flap wheel.
You can see the sizes of the tips in the pictures.
Removing tires using a tire changing machine, step by step
- We clean the wheel from dirt and remove the nipple from it.
- We place a rubber mat on the base of the machine under the rebound lever so as not to scratch the disc, then place the wheel on it.
- Raise the bump stop tab and install it on the sidewall of the tire closer to the rim.
- Lubricate the tire seat ring with soapy water.
- We insert the lever into the bumper pipe.
- By pressing down on the lever, we knock off the tire bead over the entire area of the wheel.
- We do the same on the other side.
- We put a wheel on the pipe and screw it to the machine hub using bolts.
- Using a mounting tool, we lift the tire bead and insert the straight tip of the lever under it.
- Lubricate the rim edge, bead and tip with soapy water.
- We pull the lever towards ourselves, resting it on the pipe above the wheel, while the tire bead will be removed from the disk.
- Remove the tube from the tire.
- Using a mounting tool, we lift the other side, place a lever under it and remove the tire from the rim, proceeding in the same way as described above.
Installation of tires, step by step
- Lubricate the mounting tip of the lever, the edge of the rim and the tire bead with soapy water.
- We put part of the landing board on the disk.
- We insert the mounting tip of the lever between the disk and the attached part of the landing board. The tip ball should rest against the disc, the landing flange should be approximately in the middle of the tip.
- We pull the lever towards ourselves, resting it on the pipe above the wheel. In this case, the tire bead will be placed on the disk in the middle of the mounting tip.
- When you put the first bead of the tire on the disk, lubricate the upper bead with soapy water and do the same with it as with the lower one.
- Once you have the top bead of the tire on the rim, you can inflate the tire.
Pro tip: the smaller the welding angle of the bead tip to the lever, the easier the work; it is better to attach the machine to the garage floor. When boarding, do not forget to use a soap solution.
The smaller the welding angle of the bead tip to the handle, the easier it is for the rubber to fit onto the disc. However, don't overdo it. If this angle is very small, then the lever will touch and scratch the disc when beading, so look for the best option.
Since the machine turns out to be very light, for comfortable operation it must be attached to the floor. If your garage has a wood floor, attach the machine base to it using self-tapping screws. If the floor is concrete, make a series of holes in it, install eight-point anchor bolts there and fill it with cement mortar.
To make it easier to work and to avoid harm to the rubber and rims, be sure to lubricate the tire bead, wheel rim and lever ends with soapy water. In addition, you should not work with a dirty wheel; work should always begin by cleaning it.
To repair wheels that differ from yours in the number of mounting holes, as well as the distance between them, you need to make adapters with studs. They are made of metal one centimeter thick.
How to disassemble wheels by running into a car wheel
The main difficulty in the process is due to the fact that even the car owner’s own weight is not enough to create an effort to separate the tire from the bead, which can also be affected by the loss of elasticity of the rubber.
For separation, even running a car over the wheel being repaired is used. To distribute the load, a wide and durable board approximately 1-1.5 meters long is used. The disadvantages of this shockless method are based on the fact that sometimes the rubber deteriorates. It is advisable to carry out this activity together to adjust the force and speed of the car. This option Perfect for those who want to learn how to dismantle the wheels of a car themselves, but at the same time their vehicle is on the move.
Impact demolition using a mounting bracket and a sledgehammer
The most common method is percussion. Here a massive sledgehammer is used and mounting bracket. This method used by all tire service workers and car owners before the advent of mechanized devices. In the corner, it is imperative to blunt all problematic surfaces that could damage the tire.
Dismantling without impact using a jack
Many non-impact methods use the force applied by a car jack. In a number of ways, even design features The jack and its type are not important. In road conditions, a car can serve as a fulcrum. Having fixed the jack and installed it on the point of influence, we apply force until we achieve the required result. Care must be taken not to break the device.
Without participation vehicle For dismantling, you will need, in addition to a jack, strong straps, as well as a reliable metal rod, which can be replaced with a mounting spatula or a long open-end wrench. First, we place a duct with a fixed loop under the wheel. A jack is placed under the loop from the strap, which is installed at the dismantling point. When the bar or rod is stretched along the thread, pressure occurs at the contact point.
If you plan to disassemble the wheel yourself at home, you can mount it in a permanent garage in concrete wall a fairly rigid lever of a channel, pipe or other construction profile. Such a cantilever beam will provide a reliable support for the jack.
Unbundling using two strong boards
You can do without a major overhaul by using a couple of durable boards. They are used as a lever that presses on the side of the wheel. Due to the difference in the length of the arm, a force is exerted on the substrate, which tears the rubber out of place.
Do-it-yourself special equipment for tire fitting on the road
Available for sale special devices for this event. Some models are quite bulky for constant transportation in the trunk, but are very effective in operation.
The most convenient point to start disassembling is the side opposite the spool. Before starting the event, you can add a little WD-40 auxiliary fluid. In just a few minutes the liquid will pass into everything hard to reach places and will dissolve a certain amount of the problematic material. As practice shows, this does not create an aggressive effect on the rubber.
How to find and order tires and jacks on Aliexpress at a reasonable price and free shipping
A flat tire on the highway without a spare tire is a classic situation that, in terms of frequency of events, holds an honorable first place on the list of car enthusiasts’ troubles. The vast expanses of our Motherland add brightness and depth to this problem: there is not a single auto repair shop around, and if there is, then there is a long queue.
The most natural solution– do tire fitting yourself, that is, do not depend on anyone. The solution is excellent, but to implement it you need to have some tools and skills. Where to gain skills and what tools to stock up on, read here and now.
- The angle between the beading tip and the lever must be made sharp: the smaller it is, the better the rubber will fit on the disc. But this angle cannot be made too sharp, in which case the lever will scratch the disc when beading. We need to find the optimal degrees of angle.
- It is better to do a homemade tire changing machine with your own hands using drawings. You are quite capable of preparing them.
- Consider mounting it to the floor. lightweight, so it should be attached securely. If the floor is concrete, secure the machine with anchor bolts. If the floors are wood, use self-tapping screws.
- To reduce damage to rims and wheels, lubricate the tips and wheel rim with a thick soap solution. And don't forget to wash the wheel before work.
- Sometimes wheels may differ in the number of holes for fastenings and the distances between them. For such cases, we make metal adapters with studs 1 cm thick.
