    Is it ok to change the wheel size away from the stock size? Like going from 16x6.5 to 15x10? I need new tires and 15" rim size would give me more of a selection. Would that cause any problems with 4 wheel drive fitting or anything else?

    thanks

    EDIT: OK, sorry, well, its for a 87 GMC Truck - sorry, wrong forum, so thats why i kept it a generic question. ITs just you all are so helpful here! I will have to check with some tire places tomorrow, but just wanted to know if it could be done.

    thanks

    Depending on what you have, there shouldn't be any problem. Need to fill out your profile, so we know what we're working with here[​IMG]

    No fitment problems if your running 1/2 ton gear. If you are running a D60 or a 3/4--- 1 ton front end you will need to grind the calipers. It realy doesnt matter what forum you posted this question in. Its sometimes easier to post in multiple forums for genereic questions about drivetrain and other shared parts between K5s, Subs, and Trucks.

    No prob there - Just needed to make sure we weren't dealing with something like trying to put 15"s on a Dana 70 or other oddballs. I've seen guys manage to put 15"s on K20s with no problem before - some rims have different internal diameters.

    It is not that big of a deal to grind them. I will be grinding the calipers on my Dana 60 to fit 15x10 with 4 1/8 backspacing this weekend and will post pics when I am finished.

    I had to grind my Dana 44 and its not that big of a deal at all.
    There is alot of meat on those calipers to begin with.

    Since it's a 3/4-ton you'll need to look at steel wheels. Most 15-inch aluminum wheels are too thick to fit over your front brakes, even with grinding. Seems that thatK30guy found some forged 15 inch aluminum wheels from Weld that will fit, but those babies cost around $240 each. [​IMG]

    i was planning on steel wheels from US Wheel anyway, so that isnt a problem. So its really just the wheels fitting over the calipers that is the problem right? nothing else?

    thanks

    Nobody makes 15" 8 lug aluminum rims to my knowledge--I checked Weld's website before and never did find any.

    I have the US Wheels. I have to get my rotors turned and convert my truck back to 8 lug up front so I can put mine on the front. I've got 6 lug front/8 lug back right now.
