You can go to a 4S shop or a tire specialty store. The principles of tire replacement are as follows: The specifications must be the same. Tires of different specifications have different outer diameters and section widths after inflation, and if installed on the same axle, the load distribution will be uneven. The structure must be the same. Since radial tires and bias tires have different carcass structures, their cushioning performance and axial deformation vary. Mixing these two types of tires on the same axle will inevitably lead to uneven load distribution and inconsistent wear. The material must be the same. The material mainly refers to the carcass cord material. For example, all-steel radial tires and fiber radial tires have significant differences in carcass thickness, cord strength, and heat dissipation performance. Mixing them together will affect performance. The ply rating must be the same. The ply rating is the load level of the tire and determines the corresponding air pressure standard. Mixing tires with different load capacities will result in inconsistent inflation pressure and different tire deformation. The tread pattern must be the same. Different tread patterns not only lead to varying wear but also affect the tire's grip on the road. Inconsistent tread patterns on the left and right tires will compromise the car's smoothness and may cause skidding or tailspin during emergency braking. During daily use, pay attention to the following points: Regularly check the tire surface for cracks, deformations, or other defects. As tires wear from driving, the tread grooves gradually become shallower. If the tread is worn flat, it will lose its drainage and anti-slip functions, significantly reducing the car's performance. Small cracks may also pose a risk of tire blowouts at high speeds. Additionally, promptly remove pebbles lodged in the grooves. Park on level ground whenever possible. Avoid parking on roads with thick, sharp, or pointed stones. Do not park near or in contact with petroleum products, acids, or other materials that can deteriorate rubber. After parking, avoid turning the steering wheel, as this accelerates tire wear. Do not splash water to cool overheated tires. In hot weather or during high-speed driving, tires can overheat, and the air pressure may increase. In such cases, stop to let the tires cool naturally. Never release air to reduce pressure or splash water to cool the tires, as this can cause abnormal aging of the tread rubber. Avoid sudden braking. Try to minimize frequent or hard braking to prevent accelerated tread wear from dragging against the road.
