Getting new tyres fitted can be a confusing and stressful experience.


At A&I Autos in Stonehaven, we strive to make the process as easy and stress-free as possible. We will provide helpful information about minimum tread requirements on UK roads, penalties for not meeting these requirements, and how to monitor and maintain your tyres to ensure they are safe and legal.


Minimum Tread Requirements on UK Roads


The UK’s minimum legal tread depth for tyres is 1.6mm. This applies to the central three-quarters of the tyre’s width and around the entire circumference. Tyres with less than the legal minimum tread depth can be dangerous, as they need to provide adequate grip on the road surface, especially in wet conditions.


Penalties for Not Meeting Minimum Tread Requirements


If you are caught driving with tyres that do not meet the minimum legal tread depth, you can face a fine of up to £2,500 and three penalty points on your driving license per tyre. This means that if all four of your tyres are below the minimum tread depth, you could face a fine of up to £10,000 and 12 penalty points on your license, which could result in losing your license.


Monitoring and Maintaining Your Tyres


Monitoring and maintaining your tyres is essential to avoid the penalties and danger associated with driving with tyres that do not meet the minimum tread depth. 


Here are some tips to help you do so:


  1. Check your tyre tread depth regularly using a tread depth gauge or the “20p test.” To perform the 20p test, insert a 20p coin into the main tread grooves of your tyre. If the coin’s outer band is visible, your tyre may be close to or below the legal limit and should be checked by a professional.
  2. Check your tyre pressure regularly, as under-inflated tyres can wear unevenly and increase fuel consumption. Over-inflated tyres can also affect handling and grip on the road.
  3. Have your tyres balanced and aligned regularly. This will ensure that they wear evenly, which can improve handling and extend their lifespan.
  4. Consider switching to winter tyres during the colder months. Winter tyres provide better grip in icy and snowy conditions, reducing the risk of accidents.
  5. If in any doubt about your tyres, call A&I Autos on 01569764333, drop us an email at [email protected] or pop into the office, which is located at Unit 19, Spurryhillock Industrial Estate, Stonehaven AB392NH.

Q: How often should I check my tyre tread depth? A: You should check your tyre tread depth at least once a month and before long journeys.


Q: Can I drive with a temporary repair to a punctured tyre? A: A temporary repair is designed to get you to a professional tyre fitter and should not be used as a permanent solution. You should have the punctured tyre repaired or replaced as soon as possible.


Q: Can I mix different brands of tyres on my vehicle? A: While it is not illegal to mix different brands of tyres, it is not recommended, as it can affect the handling and performance of your vehicle.


Q: Do I need to replace my tyres if they have cracks on the sidewall? A: Yes, if your tyres have cracks on the sidewall, it is recommended that you replace them, as this can indicate that they are ageing and may be at risk of a blowout.
