I read my post again and see it is not that clear now!
I sprint a W116 here in Adelaide and it has on it a set of 6.5 x 14 with those tyres that work pretty well. I have some issues with that car and not enough time to fix them by the 26/10 sprint, so I thought I would give the pagoda a go for this last event of the year. Always nice to find out what a car can do in controlled circumstances like at a track!
But I think you have answered my question, because if 7 x 15's can run without rubbing etc then my rims will work fine.
PS if I can get my act together I will video, put it on you tube and send a link here.
