Does a cracked tire need to be replaced?

[OMarley]

Tires with cracks need to be replaced. Below are the criteria for determining when a tire should be replaced: 1. Small-scale cracking: It is generally acceptable to continue using the tire. However, if the cracking is extensive and covers almost the entire tread, replacement is necessary. Not only does this affect the comfort level of the tire (noise reduction), but it also significantly reduces the tire's grip performance, posing a certain danger while driving. 2. Tire wear level: Almost every tire has a wear indicator. For passenger car tires, the wear indicator height is typically 1.6 millimeters (this is also the legal minimum tread groove depth), while for load-bearing tires, it is 2.4 millimeters. If the wear indicator is flush with the tread, it means the tire is nearly worn out and should be replaced promptly.
