Just got 18s on my P1. I noticed that on my old tyres the fronts were worn on the insides and the same on the back. Is this common or should I have the tracking done. If so how much is it roughly and where's a good place to go in the Surrey area ????
Also I noticed a slight steering wheel vibration at 80 mph but now with new wheels and tyres that has now gone. Would that have been the balancing?

Cheers
