Enter current tread depth, tire type, annual mileage and driving style. The calculator estimates remaining kilometers to replacement, projected replacement date and cost per kilometer with a calm-vs-aggressive driving comparison.
2 mm of tread - how far can you still drive?
Enter current tread depth, tire type, annual mileage and driving style. The calculator estimates remaining kilometers to replacement, projected replacement date and cost per kilometer with a calm-vs-aggressive driving comparison.
Your tread gauge reads 2 mm. The legal minimum is 1.6 mm, but wet braking performance drops sharply below 3 mm. At 2 mm you still have usable rubber, but how much? That depends on your annual mileage, driving style and whether your car is FWD, RWD or AWD. Enter 2 as your current depth and fill in the remaining fields. The calculator estimates remaining kilometers, projects a replacement date and shows exactly how much smoother driving would extend your tires.

Same tire, two drivers - one gets 45,000 km, the other barely 25,000
Driving style is the single biggest variable in tire lifespan. A calm driver on the same tires, same car, same roads gets 40-75% more kilometers than an aggressive one. This calculator takes your current tread depth, tire type, mileage and driving habits, then estimates how many kilometers remain before replacement, when that date arrives, and how much each driving style costs per kilometer.
How to use - step by step
- Current tread depth (mm) - measure at the shallowest point. New tires: 7-8 mm. Legal minimum: 1.6 mm (2/32 in). Use a tread depth gauge ($5-10) or the penny test.
- Tire type - summer, winter or all-season. Winter tires have a softer compound and wear about 30% faster.
- Annual mileage (km) - total distance driven per year. For seasonal tires, enter only the mileage during that season.
- Driving style - calm, normal or aggressive. Hard braking and fast cornering can cut tire life by up to 40%.
- Drivetrain - FWD, RWD or AWD. The driven axle wears tires ~30% faster.
- Set price ($) - optional. Enter the cost of 4 tires to see cost per kilometer and driving style savings.
- Read the result - remaining km, estimated replacement date, wear rate and cost comparison.
Before and after: calm vs aggressive driving
Based on summer tires at $600/set, FWD, normal drivetrain. The calm driver saves roughly $160/year at 20,000 km annually - just from tire wear alone.
Wear rate reference table
Average tread wear in mm per 10,000 km. Higher number = faster wear.
| Tire type | Calm | Normal | Aggressive | Total lifespan (normal) |
|---|---|---|---|---|
| Summer | 0.80 | 1.00 | 1.40 | ~64,000 km |
| Winter | 1.04 | 1.30 | 1.82 | ~35,000 km |
| All-season | 0.92 | 1.15 | 1.61 | ~56,000 km |
Practical examples
| Scenario | Tread now | Remaining km | Months left |
|---|---|---|---|
| Summer, 20k km/yr, normal, FWD | 5.5 mm | 25,000 | 15 |
| Winter, 10k km/season, aggressive, FWD | 6.0 mm | 11,000 | 13 |
| All-season, 25k km/yr, calm, AWD | 4.0 mm | 12,000 | 6 |
| Summer, 30k km/yr, aggressive, RWD | 3.5 mm | 3,600 | 1 |
| Winter, 8k km/season, calm, AWD | 7.0 mm | 32,000 | 48 |
