Ok...So .2003 Blazer LS 4X4 2DR. Stock 15" blazer rims. Bought with 265 75 R15 Cooper AT3 Tires. Looking for rims to mount a new set of rubber on 235 75 R15's for summer. Already have the rubber so just looking for wheel suggestions. Staying with 15" rim size. I'm guessing I should stick with the 6" backspacing for the rear's so the disc's will stay tucked inside the wheels. Any suggestions? Was planning on 85 Z28 wheels but nope that ain't gonna work.
