I bought a set of 20" rims and need to purchase tires. I was wondering what was the best size to get.

Depends on what width your wheels are, does your H2 have a lift, what kind of offset our wheels have, how will the H2 be used, and so on.
It all depends on the look you're going for, and the purpose of your vehicle.
Good luck on your selection!

The wheels are Helo Max 20 X 10. I never take the truck off road and it doesn't have a lift. If i decide to go somewhere off road i will put the stock wheels back on.

If you're Hummer is stock ride height, get the 325/60/20. If it is lifted I would get the 37/13.50/20. The 37/13.50/20 will still work if you're truck is not lifted but it might rub slightly.

I agree with the 325/60/20 size. Looks good and need a 9 to 10 inch rim width so Your there.
My preference is Toyo AT's. Ride good on road and as not as agressive it will work off road depending on the type of off roading. Just My preference.
