1973 plymouth cuda want to upgrade to 15x7 rallye wheels

[CudaK]

looking to upgrade to 15x7 wheel all around when ordering what would be the correct back space for front and rear?
And what is the tallest and widest tire I can get to fill up the rear wheel well to get that great stance look.

Running a 3:55 rear gear

Thanks for the info

A 275 wide tire fills the stock rear wheel well pretty much, but you won't squeeze that onto a 7" wide wheel. I've got 255 60/15 on the front on 15x7 wheels and 255 70/15 on back on 8" wide. The 255 is about all you can get on a 7" wheel. I think my wheels have 4" back space front and rear. The rear really needs more (4.5-5")to better center the tire. I'm right on the fender line but have a lot of room to the inside. I too am running 3.55 gears. The rear tire is 29" tall which is probably a little much for that gear but it goes down the road OK and keeps the revs down a bit. Gives the car a bit of a stance. I'll be going with a 60 series soon when these are worn out and ultimately a 295 or 315 with relocated springs. Current stuff is placeholder while I work on the car and I have $200 invested in the wheels and tires to get me by.
