If you're wanting an aggressive 32 for a DD, look at the TSL radials (32x10.50). The SX is a good design for serious rock duty because of the tank-like sidewalls... but that is not really a key attribute for someone who is into mud. One of our work trucks when I was a kid had bias ply tires and I'd never want to DD a set. Buy a set of TSL radials and sipe them and you'll have a tire that is tougher than the SSR's while still providing the increased road comfort of a radial. Still a swamper, but at least a radial swamper <img src="/forums/images/graemlins/lol.gif" alt="" />
