Wheel fitment

[TroyDairy]

My 1991 Chev 2500 [light-6 lug] needs some new tires. We all know they aint cheap any more and you get cheapies you got cheapies. Best $ is $700 for 265/75-16 A/T from Chinka. This is my old farm truck for fueling in the field and doing harder on it than should things. I rarely hit 6000 miles a year. I was in the local tire guys shop just to ask if he had any used ones or take-off. He said he wished, he showed my stacks of take-off 17" to 20" E range tires since for so long now that's been the standard for a pick-up/SUV. Heck we ever got a mint set of Denali rims and tires with 0 miles on for my brothers '11 2500HD for $600 last fall instead of buying new 17" tires. I, and tire guy were curious if rims from a GMT-900 or K2 would fit a 1988-1998 c/k. He did not have a wheel avail to test. I can get locally 2007 to 2016 1/2 ton 6 lug rims and new tire take offs on CL for $500-1000. 17 to 20s with Firestone, GY, or Michelin a/t tires. Then at least we would get into the bigger tire sizes for future needs and higher quality tires. Thanks

I believe that all the GM 1/2 ton 4x4 trucks have the same 6x5.5" bolt pattern (or 6x139.7 for the metric fans) with M14 x 1.5 nuts. This is confirmed with a google search only, I have not switched wheels from a new truck onto an older one.

They have all been the same since the 70s?

Yep bolt pattern is a go 1988-2018.

Thanks, me and my tire guy were mainly wondering about back spacing. The newer ones have a more + offset it appears to the eye. I should look up the back spacing. Should be some where out there....

Well I did some looking. Some lift CO had all the spacing info. Looks like a 17" from a 2014+ is 5.44" back space. A 99-06 16" is 5.22. So currently it has 2002 Tahoe rims on it so switching to the 17" 1500 ones should be fine.....on paper! Wish I could see how they look on a 88-98 body style.
