Yeah, its LT 275/70/18
Well, consider that tire at 40 psi is has a load capacity of just under 2100 pounds. I think that barely equates to your GRAWR.
On the GM-Trucks forum we determined that the folks complaining about the KO2s being short lived did not run enough air in them. Something to watch for since yours is different.
