    Looking to upgrade rims to fit 3/4 ton or 1 ton 8 lug axles, have standard 6 lug dana 44 and 10 bolt in rear. I want a 10 inch wide rim, but whats the minimum height?

    you can get 8 lug rims in:

    15", 16", 16.5", and 17" diameters. And I'm sure even more on the custom market.

    If you go with 15's you'll either have to run about a 2.5" backspacing or grind your calipers down to fit the rims. Lotsa options in the 15" tire line though.

    is there a backspacing that has no grinding? or one with the least...? more backspacing means the tire sticks out from the fender further right?

    <font color=blue>Numericly lower backspacing means the tire sticks out further. This also means you loose turning radius and there will be more stress on the wheelbearings and ball joints.

    15" Rims are rare in 15", but they are available. They are all steel. Don't even bother looking for alloy 15" 8-lug. All Chevy rears fit 15" wheels no problem (unless you do a rear disc conversion). The front is the issue. The problem is just that the 8-lug pattern is so big that it drives out the size of the rotor. Even though 1/2-ton and 3/4-ton calipers and pads are the same and the swept surface is the same, the 8-lug versions take up more diameter. 1-ton calipers will require even more grinding.

    It won't hurt anything. If you don't like your tires sticking out, like I don't...just grind more.

    I converted my 3/4 ton front to 6 lug because the 8 lug stuff was trash...now I'm thinking I'll leave it that way since I'm buying new black rims--I'll just buy two 6 lug 15x10s and two 8 lug ones for the rear...that way I won't have to grind at all!! The 6 lug stuff bolts right on the 3/4 ton front axle.

    Only problem is that if you want to carry a spare, you've got to carry TWO! I don't carry one though, I don't venture far from home so I'd just go home and get one of my spares if needed.
