At some point I've run all kinds of combos.
Presently.....well, you don't want to go there.
The front end was interesting. At one point I fit a 10 X 16 wheel with a 10 slick.
The backspace was 5 1/2 inches. It required the dust cover of the front shock to be removed. I do some testing for clearance.......full compression of the suspension and lock to lock on the steering and adjust the bodywork to suit....no rubbing allowed.
The above didn't work out well. The wide wheels gave me around 3 (+?) inches of scrub radius giving an un-curable push....oh well.......but it fit with my hand hammered flares. Now there are 8 inch wheels up there (5 inch backspace) and the push is gone with the scrub radius decreased by 1 inch......who'da thunk it?
There's a lesson here for those wanting to run spacers up front.
The rear is much more straight forward. Again the 10 X 16 wheels with a 5 inch backspace. The straight side 10 slicks have about 3/4 inch clearance to the inner fender....enough if I keep at least 19 psi in the tires.......I got the big black marks on the inners at 18 psi *once*.
