How do you know if your tyres are low? Often obvious wear is the most noticeable sign that your tyres need replacing. However, once they are in this state you could be risking breaking the law as they may already be under the legal limit. UK tyre law dictates that the legal minimum for tyres is 1.6mm of tread across the central three-quarters of the tyre all the way around the tyre circumference. If your tyre tread is below the legal minimum you can be fined £2,500 fine and have 3 points issued on your licence. The best way to stay safe and legal is to visit our garage in Swansea where we can check your tyres for you free of charge.
