The stock "HUMVEE" tires are Goodyear Wrangler RT II . Sorry I spent three years as a 240 gunner on top of one.

 

which was either the 36 very agressive looking tire or the 37 more all terrain tire

 

I was told when I bought my tires (17" BFG AT) that they were the stock Hummer tires. Didn't particularly care,but I remember they told me that.

 

They may be Hummer H2 tires, factory BFG AT's 315/75/17. They are almost 35" tall

I have these H2 rims and tireson my stock susp. 2000 3/4 ton Ram4x4 (8 lug) they fit and run great, I had to grind about 1/16 off of each rims hub center to fit the dana 60's
