Did that and its for a disco 1! the tire size calculator is good as it tells me if I put 65's instead of 55's on they will be two cm taller. Does this mean trimming of arches etc?
I run BFG 245/75/17 and 265/70/17 on range rover sport wheels on 2 53 plate standard D2's with no rubbing or touching, try them on the calculator against 18" size.
