Tyre Tread Depth Explained


The legal limit for car tyre tread depth is 1.6mm (across 75% of the tyre). However, the deeper the tread the more grip you have. At Blackcircles.com we recommend that you replace your tyres when the tread is less than 3mm as the performance of the tyre will begin to reduce significantly.

So how do you check your tyres? This video will explain some techniques to check your tyres and demonstrate how tyre tread depth affects stopping distance.


If the tread depth on your tyres is between 1.6-3mm then it is time to start thinking about ordering a new set.

Thanks to our tyre size search tool, it couldn't be easier to pick your new tyres.
