I have the roadster in a "traditional" style and using genuine Coker bias ply tires.I know it would ride better and more safely on radials but wouldn't like the look of ordinary wide white radials on this car. You have to drive on Australian roads to appreciate that any option to improve ride and safety is worth considering.A friend who runs the same bias combo that I do on his hiboy 32 tried a set of conventional radials on his roadster. He took his wife for a drive without telling her that he had swapped tires and her first comment was "what have you done to the car it seems to ride a lot better". He went back to his bias only because of the "look". I just saw some promo for the new Coker bias look radials and wondered if anyone here has taken the plunge and put some on.This tyre won best new product at SEMA 2013.I watched the video and it says available in 2014 so not sure if there has been any early release. http://www.cokertire.com/brands/american-classic-tires/american-classic-bias-profile-radials.html Click on the video in the bottom left hand also.
