I have a set of lattice wheels on my saph which was 4x4 so tyres are 205/50/1.
Rear are now bald and car is no longer 4x4 it is now back to how it should be 2wd, I now need to replace rear tyres for time being until I find a set of 17's I want.
My question is what is the widest tyres I can run on these alloys bearing in mind I need to keep them ???/50/15(for rear) i think they are 7j

When I run 17's I will be running 225/35-40/17 on back and 215/35-40/17 on front

Cheers
