Ok guys, this search has turned up some people with all different kinds of info, none that really truly states whether or not this will work. Now for reference I used to have a 295 50 15. The tires had a nice wide stance, but barely had the height to get a nice bite with. I also had a 8.5in rim with a 3.75in backspacing, so the wheel stuck out towards the wheel well and would hit on the fender if the air shocks blew, plus they had to be jacked up to keep me off the tires. This caused issues with being able to hook as the shocks messed with geometry and caused horrible wheel hop and thus I had horrible initial times. The new engine is a 521 with 620+ hp and 670+ torque. So I plan to change the rims to either a cragar ss polished or a torq thrust polished. (Note: opinions on this are welcome!) So it will be a 15x8 with a 4.5 in backspacing. Now considering the old rim was a 15x8.5 with a 3.75 in backspacing, the new rim should in theory pull the tire in towards the frame approximately an inch to an inch and a half by changing the size and the backspacing right? If so, do you guys think the 295 width will still fit? Does anybody know if a 28x12x15 tire will fit, this would be ideal so that I can use the Sportsman s/r tire. Otherwise I will be stuck taking a safe route of 275 60 15, which I lose an inch in width, but gain an inch and a half in height at least. I would love to see pics if anyone has them of this year with the tires on the back, plus rim types! Thanks in advance!
