How to Know When to Change Your Tyres Without Risking a Fine

Model: (Various brands) Various
Part: Wheel

Video tutorial

In this video, see how to determine when your tyres may be considered worn, risking a fine (as well as your safety and that of others). There is a measurement established by law, and we want to know what it is. You will need a depth gauge (the one shown in the video costs €0.44 and can be found on Ali Express with the code 4001283501843. However, it requires €8.92 for shipping.

We recommend the digital one that costs €6.89, available on ita. Grandado. Com with free shipping).

The minimum legal limit in the UK is 1.6 mm. Below this measurement, it becomes dangerous: however, there is a 'recommended' measurement of 3 mm for summer tyres and 4 mm for winter tyres. These are safety measurements.

Measure by inserting the narrow part of the tool into the grooves. There is also another method.

If you look, there are markings on the tyre corresponding to the TWI marking. When they are level with the tread, it means the tyre is worn.
