Tire Tread Wear & Life ExpectancyAutomotive & Vehicles

Tire Tread Wear & Remaining Life Expectancy Calculator (mm & Mileage)

Calculate your tire's wear rate per 1,000 km/miles, remaining safe mileage, and total expected tire lifespan based on current tread depth measurements against legal safety limits (1.6 mm).

Calculation Methodology

Usable Remaining Tread = Current Depth - Legal Minimum (1.6 mm). Wear Rate = (Original Depth - Current Depth) / Miles Driven. Remaining Mileage = Usable Tread / Wear Rate.

Frequently Asked Questions

The universal legal limit for passenger cars is 1.6 mm (2/32 inch), indicated by the wear bars built into the tread grooves.
