Just thought to share my experience with genuine 20" Overfinch Supersports. I have been running these genuine OF rims on standard size tyres (275/40/20) for nearly a year when I started to experience wobble in the steering wheel. When I took the car to the dealers they identified that all four rims are not straight on the inner lip. The service technician believes that they did not handle the weight of the car
So I rang OF who very kindly advised me that I should send the rims to them for inspection. But as I am in Slovakia the shipping costs would be over GBP 300 with no clear knowledge of the outcome
Well done OF
