Tire Wear Cost Calculator (cost per km)

Cost per km is the price of a set of four tires divided by their lifespan in km: cost/km = price / lifespan. A set costing 2000 lasting 50,000 km costs 0.04 per kilometre. It is a convenient way to compare the durability of different tire models.

Driving style, tire pressure, suspension geometry, road surface, vehicle weight and tire class. Aggressive braking, under-inflation or bad toe alignment can shorten mileage by tens of percent. Regular tire rotation evens out wear and extends lifespan.

Summer tires usually last 40,000-60,000 km, winter tires 30,000-50,000 km, all-season tires sit in between. Values are indicative — premium tires may exceed 70,000 km while budget models wear faster. Manufacturers often state expected mileage in the specs.

No. It assumes one set with the given lifespan and even wear. With two sets (summer and winter), calculate each separately or sum the prices and lifespans. Rotation affects actual lifespan but does not change the method of computing cost per km.

It is the lifespan in km divided by annual mileage — it tells you after how many years, at the current pace, the tires reach the end of their life. Remember tires also age with time; replacement after 6-10 years is recommended regardless of mileage.

Yes. The rubber compound hardens and loses properties over the years even if the tread is deep. Makers recommend replacement after 6 years and strictly after 10 years from the production date (DOT code). Low mileage does not exempt you from checking tire age.

In Poland the minimum legal tread depth is 1.6 mm for summer tires. For safety, replacing winter tires at 4 mm and summer tires at 3 mm is recommended. Below that, braking distance on wet surfaces grows significantly and the risk of skidding rises.

Not necessarily. Cost per km depends on the price-to-lifespan ratio. A set at 3000 lasting 75,000 km gives 0.04 per km — the same as a cheaper set at 2000 lasting 50,000 km. The calculator helps compare options objectively, beyond the headline price.

Keep correct pressure, rotate tires, check geometry and avoid abrupt driving. Choose tires matched to your style and mileage — for high mileage, durable models pay off. Proper tire storage also slows down aging of the rubber.

No. It covers tire wear cost only. The full running cost also includes fuel, insurance, servicing and depreciation. Treat the result as one element of your motoring budget, not a complete account of the cost of owning the vehicle.
