As we all know driving with damaged or worn tyres involves a risk of being fined, invalidate your car insurance and endanger lives too. All tyres fitted to vehicles must be fit for purpose and free from defects, tyres must also be correctly infalted to the recomneded pressure set my the manufacturers.
A tyre that is deemed to be fit for purpose must:
- be fully compatible with the other types of tyres fitted to the other wheels
- not have any lump, bulge or tear caused by separation or partial failure of the structure.
- not have a cut or tear in excess of 25mm or 10% of the sectional width of the tyre, whichever is the greater, and which is deep enough to reach the ply or cord.
- not no part of the ply or cord exposed
A vehicle with any of these faults is liable to fail an MOT test.
