GT Tyres - 3rd Generation Motor Repair & Serving Business


For over 50 years GT Tyres as it is known today has been helping customers from all over

Wales with their motoring needs. From a simple puncture repair to a complete engine rebuild

three generations of the Williams family have led from the front. Today the business is run by

Grant Williams the famous racing driver and is ever expanding and offering customers more

choice and value by negotiating hard with suppliers to ensure you always get the best deal!

Grant Williams - Races the Jaguar to an unprecedented series of wins


For those of you unfamiliar with Grant Williams, he has raced the ex-Roy Salvadori Coombs

Jaguar to a series of high profile wins in recant years including the famous GOODWOOD

St Mary’s Trophy race. In fact you will find Grant accompanied by racing legends such as

Derek Bell the famous multiple Le Mans winning driver in many long distance races. In

fact 2006 saw Derek win at Goodwood for the first time in over 40 years in the Williams/Bell

Jaguar, with Grant lapping at over 7 seconds a lap quick than Derek during his stint and over

8 seconds a lap quicker than no other than Tony Jardine.


The Williams Family have been successfully racing Jaguar’s for nearly 50 years and have built

the family business GT Tyres by using their extensive knowledge of the motoring industry.

Many thanks for getting the tyres in for

me, you were cheaper than everyone

locally and only one place on the net

was cheaper but I’d still need to get

them fitted. Very helpful, thanks.
