wheel fitment question - 72 charger - widest with some mods

[carsonp]

Sorry for ANOTHER fitment question, but i didnt see anything while searching that fit what im looking for.

So, what is the largest wheel/tire that will fit a 72 charger. Im willing and roll the fenders, but im not so sure about a minitub or move the leaf springs yet unless someone can convince me thats the only way to go past 9" or so

Rim size will be 17" for a future brake upgrade

well heres waht im thinking after a bit of research. Please chime in if you see any issues. The plan is to have it sit lower than average

with this spring relication kit you can gain about 1 1/8" of clearence

So for the rears ive got 2 options depending on where cost ends up

17x9.5 - 5.5"BS with a 275/40 (input on size?)

or

17x10 - 6"BS (custom so maybe too much $) with a 295 or 305/35 (input on size? having trouble finding a tire)


and for the fronts 17x8 - 4.5"BS with a 235/50
