daveman thought 5.5" aswell but i cant fint any specs for a 5.5" ?? only for a 6" and when its next to a 185/60 they look real close
daveman also wasn't too happy with the 7"s he ran on a 6" rim ... seemed to have a bit of roll and looked balloony

edit : thanks dd ... took a while to find the car amongst all the stuff in the garage and it's now soooo much neater with all the wheels and tyres out of the way and tidy
