Phil:
My mistake, I missed the tire spec you posted at the top.
I was thinking only about the 16.5 rims because I do not know anyone running 17 inch wheels with swamppers on an H1. Thank You for correcting me.
Buckeye:
I dont really know if he is right or wrong. I can only speak from past expierence with my truck and Swamppers. I can tell you there are a lot of H1's out there running swamppers. Most of the ones I have seen are running the TSL's or SSX's. I have only seen a couple of others running the SSR's like mine. And I have never seen one with the IROK's. I would never go back to MTR's mostly because of how hard they ride.
I think no matter what tire you get, if you climb sharp jagged rocks you are going to chew them up.
Not trying to shoot the messenger here just giving my 2 cents
