Enter your tire's Treadwear Rating, Original/Current Tread Depth, Miles Driven, and Annual Mileage — plus Driving Conditions, Climate, and Driving Style — and the Tire Wear Life Calculator tells you your Estimated Total Life, Remaining Miles/Months, and Wear Rate.

The calculator provides estimates based on treadwear ratings and driving patterns. Actual tire life can vary by ±20% depending on specific driving habits, road conditions, tire maintenance, and vehicle alignment.
Treadwear rating is a number on your tire sidewall (like 400 or 500) that indicates relative tire durability. Higher numbers typically mean longer-lasting tires under standard test conditions.
Replace tires when tread depth reaches 2/32 inch (legal minimum) or 4/32 inch for better wet weather performance. Winter driving requires at least 6/32 inch for adequate snow traction.
Highway driving typically causes less wear than city stop-and-go traffic. Hot climates, aggressive acceleration/braking, and poor road surfaces can significantly reduce tire life by 15-30%.
Rotate tires every 5,000-8,000 miles or as recommended by your vehicle manufacturer. Regular rotation helps ensure even wear and maximizes overall tire life.
Yes, based on your current wear rate, the calculator estimates when you'll reach 4/32 inch (recommended replacement) and 2/32 inch (legal minimum) tread depths.
Poor alignment causes uneven wear that can reduce tire life by 25-50%. The calculator assumes proper alignment - if you notice uneven wear patterns, get your alignment checked.
Use a tread depth gauge for best accuracy, or try the penny test: insert a penny head-first into the tread groove. If you can see Lincoln's head, it's time to replace the tire (2/32 inch or less).
