I liked my 36" Irok's (bias ply's). They rode very good on the street (unbalanced on beadlocks), and performed well offroad. From what I have witnessed, the Irok's seem to perform better offroad than TSL's. I was wheeling with a leaf sprung Toy with a similar setup to mine, his seemed to hook up MUCH better. Mine was on 38.5" SX's, and his on 39.5" Iroks. My SX's rode OK on the road, but not a good as the Iroks, but the bias ply's WILL wear out fast on the street.
