Talk about a trick question....OK lets start witht he oem 8 inch sc rims 15X8x4.5bs.
I myself like a bfg 275/60/15 rears I really dont like the sc 8 inch in the fronts so I went with the 8s on the rear and the same style 7 inch on the front with the 235/60/15.
The 8 inch sc rims work on the front but you need to watch your alignment as if its off a bit and your using outter rim weight it will shave them, so if using 8 inch 4.5 on the front use stickon inside weights.
On the R/T with the alterktion nothing on the fronts apply but the rear I run 10 inch rims for both 10.5 and 12.5 slicks or 12.5 bias.
The main pinch point is the most forward inside lil "box" where the back seat belt assembly bolts to, this box can be cut out and flat stock put there and still bolt your assembly back in.
Also in that front area the seam where the quarter panal and the wheel well meet is a approx a 1/2 to 3/4 lip, you can cut it every six inches and roll it inside and weld it up and gain clearence.
To make mine more difficult is ive a no mopar width dana, wider then a b but more narrow then an e but 12.5 slicks fit well which would be a 315 drag radial.
Really its limitless and up to your tastes, jegs is very good at listing the tread width, sidewall width, ect and with some smart thought and alot of measuring you can hit it right the first time.
What I do is for instance use a rim I know like a 8 inch 4.5 bs sc rim as well as like a 275 60 15 that jegs also lists the specs to and use that for a base to go off of.
Ive been lucky enough to be anal enough and spend enough time moching up and measuring and remeasuring ive never had to list a tire or rim due to lack of fitment.
If anyone would like pics of the mods the the front box or rolling th iner lip flush to the frame rail I can post them.
This is probably more confusing then helpful...
