Do I Need to Replace Tires with Cracks?
1 Answers
Tires with cracks need to be inspected at a 4S shop to assess the extent of damage before determining whether replacement is necessary. The specific conditions are as follows: 1. Severe wear: Each tire has a wear limit indicator in the tread grooves, with a thickness of approximately 2mm. It is recommended to replace the tire when the tread thickness wears to within 4mm of the limit indicator, or about 6mm from the deepest part of the groove. 2. Severe aging: Observe the patterns on the tire tread and sidewalls. If cracks are widespread, it indicates significant aging. Aged tires have weakened sidewalls, increasing the risk of blowouts at high speeds due to rising temperatures. 3. Frequent repairs: One or two tire repairs do not affect usage, but after more than three repairs, replacement is recommended. At high speeds, the internal temperature of the tire rises, and excessive damage, even if repaired, still increases the risk of failure. 4. Bulging or deformation: Bulging or deformation of a tire is highly dangerous. If such issues are found, it is best to visit a professional repair shop immediately for inspection. In most cases, replacement is advised. 5. Punctured sidewall: A punctured sidewall is more dangerous than tread damage. If the damage is located below the indicator near the wheel rim edge, the tire must be replaced because the steel wires in this area are weak, and repairs may not hold due to deformation during reinstallation.
