Cooper Discoverer AT3 4S and Mickey Thompson Deegan 38 All-Terrain Tyres (sizes: 275/55R20, 275/65R18)

The Hazard!

The tyres (limited to sizes 275/55R20 and 275/65R18) may develop bulges and separation of the tyre sidewall can occur, which could lead to rapid pressure loss or reduced performance.

If this occurs it can also cause loss of vehicle control, which may increase the risk of an accident.

What to do...

If you believe you have an affected tyre, please call Exclusive Tyres to organise to check and replace any affected tyres for free.
