GMT-800 tire selection

[rayra]

I don't mind the look so much, ~30-35yrs ago a 31x10.50x15 was a real common size, that and 33s or 36s. Ran 31s on my mini-trucks and later on my C-10. 265/70-17 is about 31.5", so they look 'normal' to me. And my 'off-road' activities are far more sedate now, so they're sufficient for me.

/and the lower cost don't hurt neither

I downsized from 35x12.5 r17's to the 285/75 r17's and I think, for me anyway, they're the perfect size. I'm also running H2 wheels on a 2500hd, so my situation is a bit different than yours.

Sure, it's not a real common size, but I just ordered five from Amazon. Free shipping with prime and the whole mess was about $1200 or so.

I did some fender trimming with the 35's and have a custom built bumper, so I do have quite a bit more clearance than a standard GMT800, but we have very minimal rubbing when the camper is loaded and we're flexed/turning at the same time.

Henryj, are you only running wheel spacers in the rear? What's the reasoning behind that? Great looking avy by the way

I am running 1.25" wheel spacers by the way

Just checked. I am running 1.5" for a total of 3" to the rear track. IIRC the front track is wider by 2.25" ? The rear tires get real close to the inner fender fully articulated. Spacers help that. Wider stance doesn't hurt. The rears are really tucked in. When you fill the fenders with tire it becomes very noticeable.

Interesting. On my 2002 Avalanche, the front track width is 65" and the rear track width is 66" - 1" wider than the front.
