When Should Tire Tread Be Replaced?

[ReedDella]

Tire replacement criteria: 1. External damage (severe tread damage or sidewall damage, etc.). 2. Severe tread wear (tires have tread wear limit indicators). 3. Rubber aging (fine and dense cracks appear on the tire). When replacing tires, pay attention to the following aspects: 1. For tires with low mileage, you can replace one at a time. For tires with higher mileage and significant wear, it is generally recommended to replace them in pairs. For four-wheel-drive vehicles, it is advisable to replace all four tires at once. 2. When replacing tires, ensure that all parameters of the new tires match those of the original tires as closely as possible—they can be higher but not lower. Pay special attention to the speed rating and load capacity parameters. Some tires may have the same outer diameter and aspect ratio but differ in pressure resistance and speed, resulting in significant price differences. 3. When replacing tires, perform wheel balancing. Try to align the yellow mark on the tire with the valve stem to minimize balancing errors.
