Will these Rockcrawler 15x10 6 on 5.5 w/3.5 backspacing be ok on my Blazer? Its all completly stock apart from a few engine things but im putting the 6 Inch lift soon with some 35/12.50/15 bfg's. The backspacing will be ok right? Its a lot of money im about to throw down and i dont want to tear my fenders or tires apart. Im only 18 and spending all this money is enough and im trying to save money for when i brake parts wheelin! I hope you guys can help, you always do!
