FAQ：
Q1：Do truck tires have different specifications for front and rear axles? How to match them?
A：Yes. Front axle tires focus on steering stability and braking performance, and are usually selected with moderate rigidity; rear axle tires bear the main load, so high load-bearing and wear-resistant tires are preferred. It is required that the tire specification of the same axle is completely consistent.
Q2：Why do truck tires have abnormal wear such as shoulder wear and central wear?
A：Shoulder wear is mostly caused by low tire pressure or excessive cornering; central wear is due to overinflation, which makes the central part of the tread bear excessive pressure. Abnormal wear can be avoided by keeping standard tire pressure and driving in a standardized manner.
