In radial tires, the cords are located along the shortest path between the tire beads. The breaker belt surrounds the thin and resilient carcass of the tire and ensures its stability.
In tubeless tires, the tube is replaced by a vulcanized inner layer with high airtightness. The bead of such a tire must be installed on the rim of the disc securely and tightly. The absence of a tube in the tire reduces the mass of the wheel and simplifies its installation on the rim.
Tire markings are printed on the sidewall. Tire width, construction and rim diameter are the minimum information required for tire marking
In the grooves of the tire tread pattern there are «tire wear indicators» 1.6 mm high, located at right angles to the direction of travel of the tire. These indicators range from six to eight (depending on the manufacturer) placed at equal distances around the circumference of the tire. Tire sidewall markers (e.g. letters «TWI» or an icon in the form of a triangle) show the location of the tire wear indicators.
Tires can be used up to a profile depth of 1.6 mm, that is, the profile grooves must have a depth of at least 1.6 mm over the entire surface of the tire.
Optimum tire performance is only achieved when tires of the same design are fitted to all wheels of the vehicle.
When mounting tires, do not install them on a damaged, deformed rim with signs of corrosion.
When installing a directional tire (identified by the arrow on the sidewall of the tire) it must be in the correct direction of rotation. This ensures that the tire performs optimally in terms of grip and wear.
It is especially important to maintain the recommended air pressure in the tires when driving at high speeds. Therefore, be sure to check the air pressure in your tires at least once a month and before every long trip.
Always check air pressure with cold tires.
Attention! Under no circumstances should air be released from the tire if the air pressure is increased in warm tires.
If the load changes significantly, the air pressure in the tires should be changed accordingly.
Under-inflated or over-inflated tires shorten their lifespan and impair driving performance.
Constantly checking the condition of the tires will allow you to detect intensive wear in a timely manner and eliminate its cause, which will help to avoid more serious consequences.
On a four-wheel drive vehicle, in addition, all tires must be the same model from the same manufacturer. Otherwise, the center differential, due to the resulting difference in the speed of the wheels of both axles, will incorrectly redistribute the engine torque attributable to the rear axle, which may adversely affect the vehicle's handling.
During the operation of the car under the influence of various reasons, the balancing of the wheels can be disturbed, which is manifested in the appearance of vibration of the steering wheel.
Wheel imbalance leads to increased wear on the steering parts, tires and suspension of the car, so if imbalance occurs, be sure to rebalance the wheels.
