I am currently runin 37 12.50 15 irok radials and am not happy with them. Sidewalls are way to weak. Next set i get will definately be bias. My radials are only 2 months old only beem out 3 times and 3 of the 4 tires are full of plugs on the sidewall. Maybe where most people go wheelin their fine but in so cal we wheel the hammers alot and bias is the only way to go. I learned my lesson the hard way
