Tyre Life Calculator
If you are trying to figure out how many miles your tyres may have left, then our Tyre Life Calculator helps to give an idea of an estimate on the remaining life left in your tyres.
If you already know your current tread depth, choose Option A for a better estimate. If you do not know it, Option B gives a broader guide based on how many miles your tyres have already covered and how you drive.
These estimates are intended as a guide only.
Actual tyre wear can vary depending on your driving style, road conditions and vehicle setup.
Tyre Life Calculator
Use our calculator to estimate how many miles your tyres may have left before they reach 2mm or the UK legal minimum of 1.6mm.
Choose this option if you have already measured your tread depth. This gives a better estimate because it works from your tyre’s current condition.
Choose this option if you have not measured your tread depth. This gives a broader guide based on mileage and typical wear rather than a direct tread reading.

Actual tyre life depends on tyre wear rate, maintenance, driving style, alignment, pressure and road use.
How this tyre life calculator works
This calculator uses average tread wear guidance to estimate how long your tyres may last. If you know your current tread depth, Option A works from that measurement.
If you do not know it, Option B gives a broader guide. Based on how many miles your tyres have already covered.
These estimates are only intended as a guide. Real tyre wear will vary greatly depending on the tyre and the vehicle. Other factors include your driving habits and the road conditions.
When to replace your tyres
At 2mm of tread, it is a good idea to start planning a replacement. Once a tyre reaches 1.6mm of tread depth, it is at the UK legal minimum.
If you are unsure about your tread depth, checking it manually will always give you a better idea of tyre condition than relying on mileage alone.
Disclaimer: The results from this calculator are indicative only and are not a guarantee of remaining tyre life. Tyre wear rates can vary widely based on how and where you drive, as well as vehicle condition and maintenance. You should not rely solely on this estimate. Always check your tyres regularly, monitor tread depth, and replace tyres when they show signs of wear, damage, or reduced performance.
