Those are both Bias ply. If you want to drive on the street they will rob a lot of the few ponys you have. I would recomend a radial. The Swamper SSR is what I would recomend but if your going to drive on the street a lot go with the 32 1050 15 Swamper radial (plain, not SSR). For some reason that tire rolls really nice down the freeway and it has the older more agressive pattern than the other radials. I know several people who run these. But if you more concerned with off road the SSR has an almost indestructable sidewall.
