How to Identify the Safety Indicators on Tire Sidewalls?

[EmersynFitz]

Tire sidewall patterns feature a small triangular symbol every 60 degrees, which serves as an indicator mark. By following this triangle with your hand towards the tread, you can locate two grooves on the tire surface. Inside these grooves, you'll feel a horizontal line (also visible upon close inspection) – this is the tire safety indicator line. When the tread's raised portions wear down to this line, the tire should be retired. Key details: 1. The safety line represents the maximum allowable wear limit. Tires must be replaced upon reaching this threshold to prevent overheating-related blowouts or wet-weather hydroplaning caused by insufficient tread depth for water dispersion. 2. If remaining groove depth measures ≤1.6mm (as indicated by depth markers in longitudinal tread grooves), immediate replacement is mandatory due to critically compromised wet traction.
