The durability of tires depends to a large extent on their proper use. The user has a major influence on it. It is he who should take care of the technical condition of the vehicle and use the appropriate driving technique.
Maintaining the correct geometry of the undercarriage is essential for the tire working conditions. Excessive toe-in or divergence of wheels and the wrong angle of camber cause accelerated tire wear and deterioration of grip. A similar effect is exerted by excessive play in the steering system and bearings, worn out suspension components (springs, shock absorbers) and badly adjusted brakes, which, moreover, can cause vibrations. This is especially true of the front axle. The dynamic balance of the wheels is also important. It is recommended to do this, even what 10 thousand. km mileage.
As for the operating conditions of the car, remember to load the tires in accordance with the manufacturer's recommendations (according to the load index). This prevents uncontrolled deformation of the tires, leading to a decrease in its resistance to damage due to an increase in temperature. Maintaining the inflation pressure specified in the vehicle manual, adapted to the load of the car, is the driver's primary responsibility. This value should be checked "cold" co 1-2 weeks and before embarking on a longer route, without forgetting the spare wheel. Both pressure too low, and too high is detrimental to the durability of the tire. Too low pressure significantly reduces the level of driving safety while cornering. The car "flows" in an uncontrolled manner and pulls violently with each attempt to brake. Brand new tires additionally require a pressure check after 24 hours after installing them and driving at a moderate speed for the first time 400 km, until adequate adhesion is obtained (rubbing off the layer of fat from the vulcanization mold from the tread).
Driving at high speed accelerates tire wear, Similarly, as well as sudden braking and acceleration as well as skidding in curves. To travel long distances quickly, you need to increase the air pressure (about ok. 20 kPa), in order to prevent excessive heating of the tires. For the bad ones, Pitted and rocky roads, it is recommended to reduce speed and be very careful, to prevent damage. High curbs in cities have a similar effect. Also, avoid running into grease stains, oils, etc.. Any foreign objects wedged in the tread should be removed as soon as possible. Good to remember, that in the summer, at high ambient temperature, tires wear out faster than in winter.
Tires mounted on the wheels of one axle of the vehicle must have the same structure and tread pattern. For security reasons it is also accepted, that the minimum tread depth should not be less than 2 mm for summer tires and 4 mm for winter. The indicated sequence of compliance with the tire selection criteria is as follows: manufacturer's instructions, load index, outer diameter, width, speed symbol. The assembly and disassembly of tires should be performed with the use of specialized tools. Replacing a tire with a new one must also be accompanied by valve replacement.
Tires should be stored in cool rooms, dry, dust-free, dark and airy, preferably at a temperature from -5 up to + 35 ° C at relative humidity 50-80%, at a distance of at least 1 m from heaters and radiators. Protect them from light, damp, caustic and petroleum substances.
The method of storage must ensure protection against deformation (long-term storage in an upright position requires regular rotation of the tire to change the point of contact). You can also stack them up to 1,2 m (this also applies to complete wheels), inverted what 6 weeks. After disassembling from the rim, the tires should be thoroughly cleaned of dirt for a longer period of storage, grease and traces of rust. It is allowed to store tires outside closed rooms, outdoors, but not longer than a month and covered with cloth, protecting them from the sun's rays, moisture, etc.. (or even under the shelter).
