just wondering what the difference is between a radial and a bias tire??

bias is made of much softer rubber shittier on pavement and wear, radials are made of harder rubber smoother on pavement and will last longer, bias tires wont gum up like a radial, and the bias tire get much hotter when driven on pavement
radials also have steel cords

It has to do with the way the tire is contructed, bias plys are old school, mainly only big off road tires still use this technology. On a radial tire, the plies are run from bead to bead directly across the tire (radially). In other words, the cords are perpendicular to the bead. Successive plies are just layered over the existing ones with all cords being parallel. A bias ply tire runs the plies at an angle to the bead (biased). Different layers have opposing angles, criss-crossing across the tire.

bias ply is better for offroading because their sidewalls can withstand being aired down better. If you run a radial with low pressure so the sidewall buldges a lot you will start to blow the sidewall because it weaens them a lot.
