I have been busy fitting two tyres to a Bentley Continental where the customer had hit a Pothole and split two tyres on the same side. As part of the fitting we moved the tyres around to keep the two new tyres on the same rear axle and the two older tyres on the front.
This vehicle was fitted with 19" tyres and has TPMS sensor valves incorporated in the wheels. This is something where special care has to be taken so as to not put any undue pressure on the sensor valves, as they can break quite easily.
