backspacing...

[rob h]

Looking to know what the back spacing is on 2 wheels.....hummer h2 17x8.5 and chevrolet 2500hd alloy 16x6.5........ I want to put hummer h2 wheels on my new 37-12.5-17 km2s. then put them on my 03 hd......but only if the back spacing is close with both wheels (or they will be in 2 far)......i looked for it and found all diff answers... please help guys..............

thay will fit fine. friend ran h2s on a 88-98 style 3/4 ton no problems with 33" tires. backspace is basicly the same . if i recall its 5" or 5.25" .

i run h2s on my 1ton 79 in the summer with the bfg tires.

i have 4.5 backspacing ultra 16x8s now i just wanted to know how much farther they would go in..that would be good if they were 5-5.5 backspacing.....how does a 12.50 look on em..?

The h2's are 5 & 1/2" and the chevy's are 4 & 7/8". You could always run wheel spacers.

where would i get spacers if needed...?..but i think the chevys are 6.5 wide and the hummers are 8.5 wide..so i might work out with out them..

Look in the product review section of this site.

The h2's are 5 & 1/2" and the chevy's are 4 & 7/8". You could always run wheel spacers.

5/8" difference isn't going to require wheel spacers. Even though the H2's have slightly more BS, they will stick out further because they are so much wider. Also keep in mind that the H2 is basically a fullsize GM truck with a different body on it.

i was thinking the same idea since the stock chev wheels are 6.5 and the hummers are 8.5....... do you think they will look ok on 37-12.5-17 km2s...on my 2500hd..? there are 17s on 8inch ultras now....
