如何计算Tire Life
learn.whatIsHeading
Estimates remaining tire lifespan based on tread depth and wear rate. Helps schedule replacement before unsafe conditions.
分步指南
- 1Measure current tread depth in 32nds of inch
- 2New tires typically 10/32", minimum 2/32" legal
- 3Subtract worn amount to get remaining
- 4Estimate replacement date from mileage or months
例题解析
输入
50k mi, 4-tire
结果
50-80k mi
常见错误注意事项
- ✕Ignoring age even with good tread (rubber degrades)
- ✕Not rotating tires reducing life 10-20%
常见问题
When should I replace tires?
At 2/32" tread (legal minimum); at 4/32" for safety in wet; summer tires 3-5 years, winter 3-4.
