Painted my brakes today and noticed the front tyres the inside edge has worn quite badly. There's about an inch where the tread has gone. Where as the rears are fine all over and the rest of the fronts have plenty of tread. Have only been on for about 12k. When I lowered it I have the tracking and camber checked as they said it was fine. Wheels are 8.0jx18h2 et43 with 235/40/18 tyres at 38 psi. Any ideas what may have caused this?
