Frequently asked questions
What does tire wear rate mean?
Tire wear rate estimates how quickly tread depth is being lost over mileage, usually expressed as tread depth loss per 1,000 miles.
What is the wear bar reference?
The tool uses a fixed wear bar reference of 2/32 inch or 1.6 mm. This is an informational reference and does not determine legal or safe serviceability.
Can this calculator predict exact tire life?
No. It estimates projected mileage based on entered measurements. Real tire life varies with alignment, inflation, load, road surface, climate, rotation, driving style, and measurement consistency.
Is this calculator legal or safety advice?
No. It is informational only. Check applicable local requirements and consult qualified tire or service professionals.

This tool uses a fixed wear bar reference of 2/32 inch or 1.6 mm. It does not determine whether a tire is legal, safe, roadworthy, or acceptable for use in your location. Tire tread-depth laws and inspection rules vary by country, state, province, territory, vehicle type, axle position, tire type, and operating use.
You must check the applicable local, state, provincial, federal, national, or regional requirements and consult qualified tire/service professionals when making replacement decisions.
Actual tire life and safe serviceability vary with driving style, alignment, inflation pressure, rotation practices, vehicle load, road surface, climate, tire construction, tread compound, weather, damage, age, and measurement consistency.
