The first step in checking tyre tread depth is to get good access to your tyres.
- Park on a wide, flat and even surface in a safe place off the public highway with the engine switched off and put the keys in your pocket.
- Put on the handbrake (parking brake) and engage first gear (for manual gearboxes) or park (for automatics).
- Once you have clear and safe access to the tyres you can begin the inspection.
Step 2 - Check the tread
With the tyre tread you can begin to check the depth of the tread and the condition of tyre. Don’t rely on guesswork: purchase an easy-to-use tread depth gauge so that you can monitor your tyres. Measuring tread depth is not difficult with this simple device and requires only a few minutes of time.
The legal minimum tread depth in the UK is 1.6 mm across the central three-quarters of the tread width and round its entire circumference. Check the depth of the main tread grooves in several places across and around the tyre, using the gauge as instructed by its manufacturer. Tyres also have tread wear indicators moulded into the base of the main grooves. When the tread surface is worn to the same level as these indicators, the tyre is at the legal limit and should be replaced.
However you check your tyre tread depths, if they are approaching the legal limit or if you have any doubts, get them checked professionally by a tyre specialist.
All tyres do not offer the same performances between them when they are new and these performance differences increase as tyres wear. Cutting edge technologies developed by the research and development teams at Michelin allow us to offer a level of performance and grip close to new tyres during their whole life, all the way down to the legal wear limit (1.6mm). Due to this level of performance, replacing tyres prematurely is not guaranteed to lead to a gain in safety and performance and there is the obvious financial cost but also an enviromental cost to consider.
