Prorated Tire Value & Remaining Tread Depth Calculator
Estimate the remaining usable tread depth and prorated monetary value of a tire.
Tire betterment (also called tire proration) is an insurance and warranty concept that accounts for the value you've already received from a tire before it failed or was damaged. Because tires wear over time, an insurance claim or warranty return only covers the unused portion of the tire's life — not the full replacement cost.
For example: if your $160 tire fails when it has 40% of its tread remaining, the betterment-adjusted settlement is approximately $64 (40% of $160). The other $96 represents the value you already used. This tire betterment calculator shows you exactly how that proration is calculated based on tread depth measurements.
This calculator helps you assess the remaining usable life and potential prorated monetary value of a tire. By inputting the tire's original tread depth (when new), its current measured tread depth, and the legal minimum tread depth, the tool calculates the percentage of usable tread that remains. If you also provide the original purchase price of the tire, it will estimate its current prorated value. This is particularly useful for understanding tire wear, for warranty claims, when buying or selling used tires, or just to get an idea of how much life is left in your tires. Remember that legal minimum tread depths vary by region (e.g., 2/32" or 1.6mm is common).
- Enter the Original Tread Depth of the tire when it was new. This is typically found in the tire's specifications.
- Enter the Current TreadDepth as accurately measured on the tire.
- Enter the Legal Minimum Tread Depth for your region (e.g., 1.6mm or 2/32"). The calculator defaults to common values based on the selected unit.
- Select the Unit used for all depth measurements (millimeters or 32nds of an inch).
- Optionally, enter the Original Tire Purchase Price (per tire) to estimate its current prorated value.
- Click the 'Calculate' button.
- The results will show the remaining usable tread depth, the percentage of life remaining, and the estimated prorated value if a price was provided.
