In order to avoid abnormal tire wear, timely detection and elimination of hidden problems, to ensure the normal operation of the vehicle, must be regular maintenance of tires. The maintenance of tires is divided into routine, primary and secondary maintenance. Tire maintenance period can be carried out at the same time with the vehicle maintenance. First-level maintenance 1, primary maintenance should be carried out once a week. 2、Checking the air pressure of the tires. 3、Checking the appearance of the tires, rims, screws and other components. 4、Picking out the foreign objects on the tread and tread grooves. 5、Check the spare tire and the parts supporting and fastening the spare tire. Secondary maintenance 1、Tires must be used to 8000-10000 km for secondary maintenance; clean tires and rims. 2, correct removal; check the tires, rims, inner tubes and cushion belts, make the identification of continued use, replacement, dismantling, dismantling and turning, fixed wheel assembly or scrapping. 3, the correct installation; scientific tire replacement; spare tire and assembly parts maintenance.

The service life of the tire and the quality of its own, but in the use and storage of the following points, such as to do, will greatly improve its mileage. 1, driving in strict control of tire temperature.  Vehicle in operation, due to the tread and side of the tire is constantly stretched and compressed, so that the rubber molecules and molecules, between the cord and the rubber, between the inner and outer tire, between the tire and the rim and between the tire and the road friction and heat. Long-distance driving or driving in the hot summer tire temperature will continue to rise, so that the mechanical properties of the tire material decline, wear and tear increases, and easy to cause the cord off the layer, the cord loose fracture, if the tire temperature rises to 95 ℃ there is a risk of bursting. Usually, the tire temperature from 0 ℃ to 100 ℃, the tire Kaplan cord strength is reduced by about 20%, and the strength of rubber and its adsorption force with the cord is reduced by about 50%, so to ensure that the tire temperature does not exceed 90 ℃. 2, master the tire inflation standards, to ensure that the tire air pressure in the specified value. Tire air pressure is too low will increase wear and tear and reduce mileage. When the tire pressure is lower than the standard value, tire shoulder wear sharply increased; tire pressure is higher than the standard value, because the tire grounding area is reduced, the unit pressure increases, so that the tire tread middle wear increased, while increasing the tire rigidity, so that the dynamic load on the wheel increases, easy to produce a tire burst. In uneven roads or high-speed driving, the impact is more serious. 3, strict control of the load on the tire, prohibit overloading. Overload will make the tire deformation increases, the stress on the tire body increases, the contact area between the tread and the road increases, and the relative slip increases. 4, keep the vehicle steering, braking, driving mechanism technology is good. The front wheel front beam and camber are too small, which will make the inner edge of the tread wear seriously; the front beam and camber are too large, which will make the outer edge of the tread wear seriously. The brake assembly is too tight, so that the tire rotation is not smooth and produces slippage, dragging and increased wear. The wheel imbalance is too large, the cross-tie ball joint is loose, the main pin gap is too large, so that the vibration of the steering wheel driving intensifies, will also accelerate the wear of the tire. 5、 Reasonable selection and matching tires Tire size should be compatible with the model, the size is too large, will reduce the propulsion of the vehicle, the size is too small, will make the tire overload. To take into account the tire pattern shape, pattern height, new and old degree and road conditions and other factors, reasonable with the implementation of the tire replacement on schedule. 6. Strictly observe the driving rules. Do not start too hard, try to avoid frequent braking and emergency braking. In the turn and bad road driving, to decelerate properly, beyond the obstacles, to prevent serious local deformation of the tires or scratch the tread, do not park the car in places where there is oil and steel slag gathered, do not turn the steering wheel after parking. 7、Seriously do a good job of sealing the vehicle tires, to prevent the tires from rain and direct sunlight and accelerate aging.

1、 Tire selection and installation 1. The selection of outer tire mainly depends on the following aspects: A. Vehicle type b. Purpose c. Dead weight d. Load e. Speed f. Installation position (drive wheel, guide wheel) g. Service conditions (driving route, climate, etc.) 2. Reasonably assemble tires according to vehicle performance and tire conditions: On the same axle of the car, we must achieve eight sameness: ⑴, the same specification, ⑵, the same structure, ⑶, the same material, ⑷, the same level, ⑸, the same pattern, (6), the same brand, (7), the same air pressure, and (8) the same load. 3. The standard rim of tyre design must be selected when installing tyres: If the rim is too wide or too narrow, it will change the design shape and deflection point of the tire, which will affect the service life of the tire. The rim section is too narrow, the center of sidewall deflection moves downward, and the toe part is easy to crack (usually referred to as bead crack). However, the rim section is too wide, the center of deflection moves upward, and the shoulder is easy to void or the shoulder carcass steel wire is broken (commonly known as zipper blasting). 2、 Use of tyres Maintaining the correct air pressure is the key! 1. For new tires used for the first time, the air pressure can be filled by 103% of the standard used, and the newly installed tires are installed on the outside of the rear axle; When the new tire used on the rear axle reaches 3000 km, remove it for inspection. If there is no problem, replace it on the front wheel and adjust the air pressure to 101% of the standard. 2. Tyre pressure management: A. Inflate according to the instructions of the vehicle and tire manufacturer. B. At the initial stage of tire use, the tire size will become larger and the relative internal pressure will be reduced due to bending and heating. Therefore, the air pressure should be replenished after 24 hours of use or 2000~3000 kilometers of travel. C. The air pressure of multiple wheels shall be the same. D. When driving at high speed, the air pressure should be increased by about 10%. E. The tire pressure will rise due to temperature rise during driving, and it will return to its original state after cooling. Therefore, when the internal pressure rises, do not bleed. F. After inflation, test the valve for air leakage and lock the valve cover. G. The tire pressure shall be measured at normal temperature. H. Carry out regular air pressure inspection, and the spare tire shall be available at any time. 3. Vehicle inspection, vehicle positioning: The vehicle positioning has changed when the following conditions are found: A. The steering wheel is not centered or shakes left and right when driving straight. B. When releasing the steering wheel with both hands, the vehicle may deviate to the left or right. C. Abnormal tire wear (eccentric wear, abnormal wear). D. The body is unstable. E. The vehicle makes abnormal noise. 4. Tire rotation: Replacing tyres can effectively save costs! A. In order to make each tire wear evenly B. In order to save costs. ※ Correct tire rotation can save about 20% of the cost!
