I'm looking to slap a set of ten spoke turbines on my jeep and I've seen differing answers here and there. I need to know backspacing and the offset. Right now I'm running fuel lethals 15x10 with 3.75 backspacing and -43mm offset and 33x12.50r15. I know the turbines are 15x7 so I'm gonna come down to 33x10.5r15s to save the center of the tire cause mine is a daily. I know the backspacing is more important for me because I don't want my tires hitting my suspension. I'm running a 4.5 lift with trimmed fenders and flares, so I'm not worried about anything hitting there. I just really love the look of the turbines and have access to a set for free. I'd love to have them cleaned up and powdercoated to have a nice set of jeep wheels. If anybody can give me the numbers I'd appreciate it.
