Tyres are the only part of your car in contact with the road, so keeping them safe matters more than almost any other check. Most tyre problems can be spotted in a few minutes once a month. This guide covers five simple checks every driver can make, and when to ask a professional to take a closer look.
1. Check tyre pressure every month
Check pressures monthly and before long trips, when the tyres are cold. Use the pressure on the placard in the door jamb or in the owner’s manual, not the maximum printed on the sidewall. Under-inflated tyres overheat, wear faster, and use more fuel. Over-inflated tyres grip less and wear the centre of the tread.
2. Check the tread depth
The legal minimum is 2 mm in many places, but grip falls well before that, particularly in the wet. A simple test is to insert a coin into the tread: if you can see the top of the coin’s outer edge, the tread is worn too far. Replace tyres that are close to the limit.
3. Look for damage on the sidewall and tread
Look for cuts, cracks, bulges, and objects stuck in the tread. A bulge on the sidewall means the internal structure is damaged, and the tyre should be replaced promptly. Do not drive on a tyre with a bulge or a deep cut.
4. Check for uneven wear
Uneven wear can point to a pressure problem, a balance or alignment issue, or worn suspension. If the edges or centre of the tread wear faster than the rest, have the tyres and alignment checked by a professional.
5. Check the tyre age
Look at the DOT date code on the sidewall. Many manufacturers advise replacing tyres after a set number of years, often around six to ten, regardless of tread depth. Old tyres can crack and lose grip even if the tread looks good.
Fitting and wheel checks
Fitting new tyres, balancing and repairs should be done by a qualified tyre fitter. Check that wheel nuts are tightened to the torque specified for the vehicle after any wheel change, and re-check after the first short drive.
Frequently asked questions
How often should I check my tyres? Check pressures and inspect the tread and sidewalls at least monthly, and before any long journey.
Can I keep driving on a tyre with a small puncture? Only if it is repairable and the damage is in the tread area. Have it checked by a fitter as soon as possible.
Do I need to check tyres in winter? Yes. Cold weather lowers tyre pressure, so check pressures more often.
