So after talking to the Hummer God (name not given for security reasons
) I decided that I must retract my earlier comments of buy any tire similar to the MTR. It is now my understanding that Super Swampers are sh^t because they are not rated for H1 use and may be sufficient for an H2 but barely because the weights aren't too far off. Furthermore, I have been informed that after a long drive on the highway the swampers tend to get too hot and shred on the trails. He didn't even give them a year of good use. Another losing proposition would be the PJ dirt grips although better than the swamper. He said these are better and should last at least a year but plan on a faster replacement. He said the best tire (for my h1) in lieu of the MTR (since they're all rolling near the borders) would be some version that BFG offers. He said they ride the best, last the longest and are rated properly.
Take it or leave it, everyone has an opinion but I tend to listen to guys that race for Hummer and know more about Hummers than the General.
