What are the effects of different tread patterns on the left and right rear tires?

[StevenLynn]

The difference in tire tread patterns leads to varying degrees of wear during driving. The effects of having different tread patterns on the left and right rear tires are as follows: 1. It affects the tires themselves and can also cause inconsistent braking resistance, keeping systems like anti-skid continuously active, which can significantly damage the vehicle. 2. When the car needs to brake suddenly at high speed, the difference in tires may cause uneven force distribution, potentially leading to traffic accidents. 3. If conditions permit, it is best to use tires of the same specification, structure, manufacturer, and tread pattern (load index, speed rating) for all four tires. Proper rotation can help maintain a consistent wear rate, ensuring uniform performance across all tires. 4. If for some reason only the front and rear tires are of different brands and tread patterns, it is acceptable, but the same specification, structure, manufacturer, and tread pattern (load index, speed rating) should be used on the same axle.
