Whats the biggest rim/tire you cn run on the rear of a 1970/1971 cuda


(will 15 x 10 w/345/50/15 w/5inch backspace fit on the rear if you have a 3'' spring re-location on the back?)

Generally a 295/50/15 on an 8" rim with a 4" backset

Here is a pic of mine but it had 10" wheels with the bolt on rear spring relocator... 5" backspace

My buddy has 30X12.5 on his '70 Cuda.  I don't know what size wheel or backspacing.

   OK more pics

17x9.5
305/45R17

offset hangers, rolled fender lip 6.9" backspace 3/4' spacer longer studs

without working the outer edge of the inner wheel well this works out ok. I like having the tires tuck up in the wheel well, if you don't want that look you can go wider I think with the ride height higher

I think "will 15 x 10 w/345/50/15 w/5inch backspace fit on the rear if you have a 3'' spring re-location on the back?" would work fine if you cut the wheel wells open some (the inner portion). Seems like when you get around the 29-30" diameter tires you might have to lengthen the opening of the wheel well depending on if you are going to run slicks/bias plys or they might rub on the top end at the track.

For the looks of those pics, your old tires must have gone out in a blaze of glory.

I have N50's on the rear. Big boots for sure. 15" rim of course.
