My front tire seems to be wearing unevenly on the right side. I have noticed a bit of feathering on the tread & a concave shape on that side. Checked the pressure last week & was at 32 psi. Have since corrected that to 36 psi. Could that have been the problem? Tire has done 5500 km. Left side is fine & back tire is wearing evenly. Not many roundabouts in my area & do as many left turns as right. Mate suggested it could be due to the camber in the road but would have thought that would affect wear on the rear as well. Both tires were worn on the right when I bought it, I put that down to the city riding of the previous owner(roundabouts). Anything I need to check?
