What the title says, Can i run 15x9 with 4.5 B/S on stock 7.5 rear with 275.60.15's? According to the turbocad drawing i did with everything to scale, i can do it, tight fit but can be done, also im not drag racing, It's a daily driver right now. If theres clearance issues i will go to air shocks.
Can i run this combo?

I have vette ralley's that have 4" b/s, with 295/50s it's real close to the inside. Less width to the tire, more to the rim, everything moving in a half inch, be close but think it would fit....
I tried 275-60x15 goodrich drags on weld pro stars 15x8 with 4.5 bs rubbed inside frame badly,added 5/16 inch spacers to get clearance,this will work til I get frame notched....
hmmm well with the turbocad drawing i did, it says they will be 1/2 inch away from frame, and thats the edge of the tire. Everything is to scale EXCEPT the measurement from the mounting point on the axle to the frame. thats the last dimension that id need to see if they'd fit, although a factor to consider would be once weight is on the tire and how it bulges.
RSH4364, you could be right about my setup, il have to see what happens once. Also, when you did that spacer did you run longer than stock lug studs?

Well, i Figured 10 would be too wide with my 7.5 gm rear, althought i know a guy that runs 10 inch on his car they come to the end of the body, wouldnt tuck in, so he has heavier duty springs with air shocks at 20 PSI to hold the car up so the tires dont rub. All spring holds it up, not too much on the air shocks it wouldnt be a bad option for me, its gonna be a street car anyway, till i get another car its a D.D then its the weekend give em H*ll toy.
I ordered 15x8 with a 3.5 B/S that i will put 275's on i know it will work other people have done it without using spacers, or any other mods. although air shocks will be needed to stiffen the back up.
thats what i had on my 79 malibu the first time around,tires rubbed fender lips,unless i aired up to truck height,then airshox let go and cut sidewalls up,now i have airbags,4.5 bs wheels 5/16 spacers 275-60x15s and i was able to lower rear 2 inches,no more rubbing and looks and handles much better..in fact even my 255/60x15 rubbed on the 3.5 bs wheels wen hitting bumps ..
