I have run both the bias and radial 36 iroks both rode about the same on the street . i like the look of the bias more . i got about 20,000 out of the bias . the radial i drove over 10,000 miles last summer all over the US in a fully loaded 4 runner and they wore very well . I have priced them lately but the radial was alot more than the bias and i dont think it was worth it .
