How to Know When Your Tyres Need Replacing

Your tyres are the only contact between your vehicle and the road, making their condition critical for safe driving. Worn or damaged tyres increase stopping distances, reduce grip in wet conditions, and raise the risk of a blowout.

Knowing when to replace your tyres can prevent an accident and save you from a costly fine. Glasgow Mobile Tyre Fitters can inspect your tyres and advise you free of charge.

Tread Depth: The Legal Limit in the UK

UK law requires a minimum tread depth of 1.6mm across the central three-quarters of the tyre. Most safety experts recommend replacing tyres at 3mm, as wet braking performance drops sharply below this level.

Use the 20p coin test: insert a 20p into the main tread groove. If the outer band of the coin is visible, your tread is below 3mm and replacement should be considered soon.

Other Signs Your Tyres Need Replacing

Sidewall cracks, bulges or bubbles are serious warning signs. These can indicate internal structural damage that puts you at risk of a sudden blowout, especially at motorway speeds.

Persistent vibration through the steering wheel, uneven wear across the tyre surface, or visible damage such as cuts and embedded objects are also reasons to seek a professional assessment.
