    Please give me some good news.

    Besides the heck of a time and 5 hour search I had finding someone to mount my US Wheel chrome rims to my new Goodyear 33x12.50x15 MTR's, I now have the problem of mounting them on my 89 Blazer. When I placed the tire/rim on the Blazer it touches the brake caliber, thus not allowing the wheel to go all the way on. When I ordered the rims I made sure and checked the backspacing I needed before I placed the order.

    What in the world can I do to fix this dilemma? Let me know what info you may need to help me...guns loaded, just sitting here with it cocked.

    :(

    I started the grind process on the driver side wheel caliper. I spun the wheel a few times and found the high spots. However, after a small amount of grinding I have realized that a large amount will need to be done to the caliper on the side.

    Would it be against any safety rules for me to use a 1" spacer in the front to get the clearance I need? I just ordered a 2" spacer for the rear from Harold's.

    The problem I see is that there are two bolts that hold the caliper on (I'm not a brake guy so forgive me). I'll have to grind them too.

    might have been good for someone to ask that kind of question before giving advice. :rolleyes:

    are the wheels 8" or 10" wide. For 8", i believe you need 3 5/8" backspacing. i don't know about 10"s.

    I do not know about 4 3/4 backspacing but I do know that a 15X8 with 4 1/4" backspacing will fit with no problem on your setup. I have to grind the **** out of my front 60 to get the same combo to fit.

    Did you say 6 lug, as in 1/2 ton? Should be no grinding required. But, 4.75" back spacing is a bit much...

    Ya they sure will. The only problem with your other wheels is you are hitting the dropwell of the rim with the caliper due to the large backspacing. 3 3/4" backspacing will keep your scrub radius near what it is with stock wheels.
