tires. The service is widely available, in demand, and doing it yourself is dirty and troublesome. It's easier to take "to the address." But how to choose this very address so that they help, and not harm?
Eduard Raskin
With rubber, its installation and repair today there are no difficulties even in the most remote and reserved corners of Russia. Perhaps the masters will “wrinkle” their noses when they see the RunFlat tire, which allows you to continue moving after a puncture, or they will scold you for too large a disk radius. However, "hard currency" will quickly resolve this issue.
Problems in tire fitting, as a rule, begin at the moment of installation of the already assembled wheel in its rightful place.
Few people would guess to treat the surface with copper high-temperature grease. Caring for colleagues and the client is not the strongest side of domestic business. Forgetfulness will turn into difficulties during the subsequent uninstallation of the wheel - the disk will “stick”, efforts and some skill will be required.
But the worst flaw is the tightening of the bolts. First, the fastener must be placed in a strict order, and not as it should. For a four-bolt hub - 1-3-4-2, for a five-bolt hub - 1-4-2-5-3, for six - 1-4-5-2-3-6. And nothing else, because the wheel can stand up crooked, causing unpredictable behavior of the car on the road. By the way, you can count from any hole - it is important to follow the principle here.
Secondly, tire shops, as one, neglect the key safety element of mounting a wheel rim on a car. The force with which nuts and bolts are screwed. For each car, this indicator is set by the manufacturer. For example, the wheel bolt tightening torque for LADA Granta is 80—90 n / m (8.
15-9.17 kgf / m), and for the "Niva" - 62.4-77.1 n / m (6.37-7.87 kgf / m) Have you ever seen a dynamometer in the hands of a tire fitter key?
According to the technology, the installation should look like this: on a previously jacked-up car, the wheel is carefully installed and fastened with bolts or nuts by hand. Not with a trowel, not with a key, but with a hand, as far as nature allows. After that, with a special tool with the ability to set the limit force, tighten all the bolts in the same order in which they were “baited”.
If the rules are neglected, brushed aside or done “as taught”, then you will be surprised at a wheel flying at a neighbor downstream, as well as unpleasant emotions when the connection “does not give in” at the most crucial moment, or, worse, the pin unscrews from the hub along with nut - not worth it. And finally: the master, which gave ground for reflection, turned the nuts with a force of 16 kgf / m. In field conditions, on a dirt road, in a deep rut, out of five, only two were unscrewed.
The rest "came out" along with the studs.

Tire inflation with nitrogen and 7 more wirings at the tire fitting
In mid-late autumn, car owners storm tire shops. However, you can disassemble the wheels yourself. We'll show you how to do it. We will need a special tool, as well as a screwdriver to unscrew the wheel valve, and a couple of pliers to help remove the tire from the rim.
To rid the rim of the tire, we bought a simple but very useful device - a mechanical wheel beader.
There are several options on the market, but we chose the one produced by the Sorokin company. It is inexpensive. Thanks to the ability to adjust the retractable linkage, tires can be removed from discs of different diameters. You only need to select the desired position of the rod and tighten the two bolts holding it, after which you can start working.

Is it possible to pump up a wheel without a compressor - the experiment "Behind the wheel"
We took a 16-inch wheel. It is more convenient to remove the tire if you put it on the floor. In order not to scratch the aluminum disc during work, we will place a sheet of foamed polyurethane under it, which is used in construction for sound and heat insulation. We unscrew the cap on the valve, holding it with a finger, unscrew the spool so that it does not pop out under air pressure. The tire starts to deflate.
Before carrying out work with the help of a special tool, it is necessary to moisten the working edge of the disc with a penetrating liquid.
Otherwise, we risk damaging the disk. Also, the liquid, having seeped under the edge, will facilitate the removal of the wheel from the humps.
We apply our device to the disk. Its hook in this case should protrude from the mandrel by 7–8 cm. For reference, this is one hole on the retractable rod. With a hand, we press on the device from one side so that it goes under the protrusion of the disk, and we wind the hook under the disk from the opposite side. We spread the levers of the device in different directions. The main thing is not to try to throw off the tire immediately, but to move it off the hump gradually. Otherwise, the tire may be damaged. Please note that the device should not be inserted near the wheel valve.

Pulling out and moving the tool, slowly move the tire off the hump around the entire circumference.
You can hold the side of the flight attendant, where there is no hook, with your foot. Having removed the tire on one side, turn the wheel over and do the same work on the other. Don't forget about lubrication. By the way, it is not necessary to use a liquid, a silicone composition is also suitable.
We removed the tire from each side of the humps. It remains to take mounting blades and completely remove the tire from the disk. We process the belt with penetrating lubricant. It is advisable to get on the inside of the rim, this will make things easier. We start the first blade under the tire. It is convenient to do this in the area of the wheel valve. We take the assembly aside in advance so as not to damage it during work. Hold the mount with your foot. We insert a second spatula next to it and lift the edge of the tire with it. We do this along the entire inner circle, also gradually. We removed the tire from one side of the disc, it remains to do the same on the other. We turn the wheel.
