I would never recommend Coker tires. They have a terrible reputation in the old car community (if you're going to drive your car regularly).
I had a belt separate in a Coker Classic after less than 10,000 miles. I know personally of two other people who had similar problems and have read other bad stories about them on other forums.
Don't even get me started on Coker bias ply tires. Even Corky Coker told the president of the Peach State Cadillac Club that he wouldn't use them if the car was driven regularly. (they're for show)
If you insist on a wide whitewall, I would only recommend Diamondback tires. I've installed them on 2 Cadillacs . They are the best tires I've ever had on the car. They have a bias ply appearance but are modern radials.
www.dbtires.comA guy on this forum purchased a set of DBs for his truck from Summit Racing for the same price as buying directly from Diamondback but got free shipping. Saved $100.
Since I don't want whitewalls on my truck, I have 16" Firestones on it that I bought on Amazon for $94 each. They handle perfectly and I didn't bother with a front end alignment. 10,000 miles later and they're wearing perfectly evenly.
