all my tyres are worn on the inner edges, is this a common thing for the saphs..??

its 2wd, with Koni's..not sure what springs but lower, and Diamond cut 7 spokes.

As ive only had the car a couple of months, i dunno if they have been swapped front - rear at some point.

Any advice as where to get new rubber an what to put on..?? The N/S front catches the arch so i might look at swapping the 7 spokes for some 16's or even back to the original ford ones..
