New shoes on our 2007 H2
As part of my continuing rejuvenation of our 2007 Special Edition H2:
Guys, I can tell you after a week with new set of 4 TA KO2 on the Hummer, that these tires are fantastic.
These (vs. the old KO that came on the wagon) take up to 65PSi.
I pumped them up to 50 PSI (I think door sticker says 37 or something close to that).
And the ride has firmed up. Less body lean. Less rolling resistance. More coasting. Better mileage likely.
Love them.
Just hope the centers do not wear out faster than the tire edges.
Given how hard the H2 is on outer edges on the fronts, that may equalize the wear.
And given how hard they now ride, they definitely have to be aired way way down for off-road.
The old KO only took 50psi max. and I never pump up to the max. So the ride was way softer.
I had 65K miles on them with 50% tread left. Incredible.
I hear the KO2 will actually wear faster, converse to what Michelin claims.
What have you guys experienced with them?

I have 20k to 25k+ miles on my KO2s.
The only visible wear I have is due to a bad alignment. The rears look like they barely have any wear. I'm running 42ish PSI, mostly to compensate for bad lower ball joints & some other issues I'm trying to address.
When I had an 03 H2, I ran the KOs at max & never felt the road, lol. I'm not sure the original KOs rode better because they were Load D or the suspension was great & not worn out (or both).
What size did you get?
I have the 35x12.50r17 & they measure out to 33.5". A poster on Hummer4x4 said that his 37s measure out to 35.5.
I'm expecting to get about 3 to 4 years out of them (75k to 100k miles).
I'm seriously considering dropping the new Michelin Defenders on them once the KO2s wear out. It'll be an almost entirely street rig at that point, so the lighter tire weight, better ride (not that the KO2s are bad), and LRR. Oh, since I have the stock 20s, it let's me use them instead of having them sit in the garage all the time. I'll keep my 17" wheels for mud tires.
