What is it with you guys ragging on Coker? Like all they make is one tire. Don't you know that Coker carries all different brands? And types of tires? They sell 2 or 3 different brands of wide white radials. They own almost all the old tire molds to make authentic bias ply tires for everything from Model T's to modern foreign cars. If you're buying original type Firestone bias, or Goodyear, Coker made them. I give Coker a lot of credit for saving and making new tires from the old molds, they could have just as well been destroyed, back when the hobby was not so popular. And I certainly give the credit for being first with doing the wide white radials. I drive customs, and back before they were available, all my custom buddies wanted radials so badly, some even used crappy porta walls so they would get a good ride and handling. As for problems? Could be the old molds, could be poor manufacturing quality ( I believe some tires are made offshore) or just bad batches of tires. Could even be that the old molds were never perfect, as those old cars weren't meant to go faster than 55 MPH. I don't know about anyone else, but I'd rather be able to buy and run the old tires, or WWW radials, even if you have to go through a bit of balancing problems, or light shaving to get them right. Even going through the trouble of returning them, if necessary, Coker has good customer service, in general. Better than not having them at all.
