Do vehicle and tire manufacturers recommend replacing tires in sets?

Replacing tires in sets, particularly all four, is recommended by vehicle and tire manufacturers for several important reasons. One major benefit of doing so is maintaining balanced handling and stability. When all tires are new and have the same tread depth, they provide uniform grip on the road, leading to improved traction and safer performance, especially in adverse weather conditions.

Moreover, uneven tire wear can significantly impact how a vehicle drives. Replacing just two tires, especially if they are on the same axle, can result in a mismatch in responsiveness and handling characteristics, which could lead to potential safety issues during cornering or in slippery conditions.

In addition, having a complete set of tires that are the same type and tread pattern helps in maintaining consistent performance and can enhance the longevity of the tires. It also ensures proper braking performance, as differing tire characteristics can lead to uneven braking distances.

For these reasons, many manufacturers advocate for replacing tires in sets of four to ensure optimal vehicle performance and safety.
