What are the consequences of having different tire tread patterns?

[StHarper]

The main impacts of having different tire tread patterns on a car are: uneven grip performance, which can cause the vehicle to pull to one side while driving. Tire replacement guidelines: 1. When tread depth decreases and wear intensifies, it means the vehicle's braking distance will be affected. Therefore, for safety reasons, tires should be replaced in advance. Generally, when the tread thickness reaches about 8 millimeters, replacement is recommended when it wears down to 1.6 millimeters. 2. Inspect the patterns on both the tread and sidewalls. If cracks appear, it indicates severe tire aging, meaning the remaining mileage is limited. In such cases, replacement should be considered as soon as possible.
