Just had a set of Bridgestone Alenza 275 55 R20`s fitted to a set of Range Rover Sport wheels that are 20 x 9.5 ET 53. I removed the plastic cone bits from the strut tops and with a hot air gun flattened out the bulge for the fuel filler in the RHR wheel arch liner. So far zero rubbing and a nicer ride than on my previous 275 45 20`s.
After a day of driving at various speeds with a GPS speedo the car speedometer is now bang-on accurate before the speed shown was always about 5% fast.
