Over the course of time I have had L322 18" Rims with 255/60/18 tyres, RRSport 19" Rims with 255//50/19 tyres and now Supercharger Rims with 275/45/20 tyres and have Never had any Wheel Bearing Failures, Stability or Steering Issues, Uneven tyre wear or Wheel Balance Problems of any description whatsoever. And have driven this car at speeds well in excess of 100mph in total confidence.
However I have proably just tempted fate.
Cheers
