TireSize tire wear calculator
Forecast when your tires give up grip.
Track tread depth, rotations, and mileage to stay ahead of replacements. TireSize shows how your driving style affects wear.
Tire Wear Calculator
Enter original and current tread depth plus miles driven to estimate wear rate, months/miles left, and when you'll reach 3 mm (recommended) and 1.6–2.0 mm legal limits. Adjust for climate and driving style.
Track your tire usage and plan safe, cost-effective replacements

Tire Wear Guidelines
Tread Depth Standards
| New tires | ~8–10 mm |
| Recommended replacement | ~3–4 mm |
| Legal minimum | 1.6–2.0 mm |
| Winter tires | ≥4–6 mm |
Wear Factors
- • Driving style (aggressive vs conservative)
- • Road conditions and climate
- • Tire pressure and alignment
- • Vehicle weight and load
- • Tire quality and compound
Tips from the TireSize tire wear calculator
• Rotate tires on the schedule recommended by TireSize to keep tread depth even.
• Use the calculator before long road trips to determine if you need a new set.
• Combine with TireSize tire pressure planning to maximize tread life.
Helpful links
- Capture dimensions up front with the tire size calculator before logging tread depth.
- After estimating wear, head to the tire cost calculator to plan the replacement budget.
- For faster wear on lifted builds, double-check gearing via the gear ratio calculator.
Tire wear calculator FAQ
How often should I rotate tires?+
Follow your vehicle manual or every 5–7k miles. Enter your intervals to see how it extends tread life.
Can I predict when tread hits 4/32" or 2/32"?+
Yes. Input your current depth and projected mileage; the calculator estimates when you reach key safety thresholds.
Does alignment affect the results?+
Uneven wear shortens tread life. Pair this with a fresh alignment and record new depth after adjustments.
What about different axles?+
Track front and rear depths separately. The calculator accepts multiple readings so you can gauge staggered wear.
How do I verify replacement timing?+
Use the Tire Cost Calculator to budget replacements once this tool predicts your tread will dip below legal limits.
