How to Use This Calculator
- Enter Current tread depth (32nds inch), select Driving style, and enter Annual mileage.
- Select Tire quality and Alignment condition, then enter Price per tire ($).
- Review the Estimated remaining miles result.
- Use Estimated remaining months and Tread life remaining (%) to inform your decision.
- Check Tire cost per mile (set of 4) and Next rotation (miles) for additional context.
How the result changes with Current tread depth (32nds inch)
| Current tread depth (32nds inch) | Estimated remaining miles |
|---|---|
| 2.1 | 0 |
| 4.85 | 19,474 |
| 8.15 | 54,211 |
| 11 | 84,211 |
What each input means
- Current tread depth (32nds inch)
- Measure with a tread gauge. New tires = 10/32". Penny test: if Lincoln's head is visible, you're at ~2/32".
- Driving style
- Select the driving style
- Annual mileage
- Miles driven per year.
- Tire quality
- Select the tire quality
- Alignment condition
- Select the alignment condition
- Price per tire ($)
- Cost per tire for amortized cost calculation.
What each result means
- Estimated remaining miles
- Miles left before tires reach 3/32" recommended replacement depth.
- Estimated remaining months
- Months of use remaining at your annual mileage.
- Tread life remaining
- Percentage of usable tread remaining.
- Tire cost per mile (set of 4)
- Amortized cost per mile for a set of 4 tires.
- Next rotation (miles)
- Recommended tire rotation every ~6,000 miles.
- Replace immediately?
- 1 = tires are at or below safe tread depth, replace now.
