ok so 74 duster with 8 3/4 rear. will a 275 tire work on the back with stock backspacing. im thinkin a 275/60/15. i dont believe there will be clearence issues cause i have a 255 on it now with a decent amount of room but would just like to know. thanks.

 

What 8 3/4 do you have,A body?,B body?, what rear brakes?, small or large bolt pattern,all this info is important on using 275/60-15 on the rear.

 

its an a body 8 3/4 . 489 case 3.55 gears. ssbc rear discs. smallest rim that will fit with the kit is a 14 so im good there. also its the large bolt pattern 5x4.5.

Should be no problems to run a set of 15x8 rims with 4 1/2 inch backspace and 275/60-15 tires. Thats what i ran on my '71 duster with big bolt axles and the large 10 inch brakes,had 1/2 inch clearance at least from sidewall to leaf spring. I have since moved up to 10 inch rims with 275/60-15 tires,tight fit.

 

thanks alot.
