Coker tire problems

I'm looking for a set of wide whites soon and from what I have read here they be company of choice...that's great customer service!!

 

Now THAT is customer service....I buy my white walls from them

 

I bought a pair of the ribbed front Firestone dirt track tires, and some 8.20-15 Firestone dirt track rears for my '27 Track T and I have had nothing but problems with them, they vibrate badly. Mine have D.O.T. numbers on them, but the reps that I have talked to at Coker say that those tires are for display only and that I will have to live with them. I see those tires on cars at a lot of shows, and the car owners say that their tires are nice and smooth, but mine suck!!!
