SSR\'S OR MT/R\'S? Was just wondering if anyone has had the ssr's and then went to goodyear mt/r's. I have had super swampers before and liked them, but have been hearing alot about the goodyears. These will be 35x12.5x15's on a truck that is a daily driver and trail truck, about 60- 40. Not many road miles since I live 6 blocks from work. Thanks for any pro's or con's.
