I have Cokers on my Studebaker. I have had some problem with the whitewalls bubbling up close to the bead, they have replaced my two front tires for me adjusting them based on remaining tread. The service has been excellent. Now I am noticing a bubble on one of my rear tires.
I think if I ever replace the Cokers, I may look at Diamond Back. They put whitewalls on other tire types. I am looking for something that will give me better traction.
