Tyres below legal tread depth or underinflated - up to £2,500 per tyre - max. £10,000

Tyre pressure and tread must be checked by drivers before going on a long journey. 1.6mm is the minimum legal tread depth, "and bald tyres affect your car's grip and are unsafe" especially facing wet conditions.

If tyres are underinflated that can "also affect your car's handing and put you at risk of blowouts." Tyres must be up to scratch otherwise this will lead to hefty fines of up to £2,500 per tyre, and "up to three points on your licence for each tyre that is found to be illegal."

Cinch motoring expert, Ben Welham shares how to check your tread depth if unsure, "using a 20p coin, make sure the grooves cover the outer ring of the coin." To check tyre pressure you have to examine your owner's manual, sometimes there could also be a "sticker in the driver's door frame or fuel cap and matching your wheel/tyre size to the reading from a tyre pressure gauge."

At the last resort, if you are still not sure, "most chain garages and motoring retailers will check your tread and pressure for free." Cinch also have their own guide to "looking after your tyres and what happens if you don't"on their website.
