Diamondback takes a tire manufactured by someone else (say Toyo or Dayton) and puts the redline stripe on it.
Coker finally has a radial tire with a piecrust edge like a bias ply, but I haven't heard yet how well they work:
https://www.cokertire.com/american-c...whitewall.html They have an 8.00R14, in either a wide whitewall or a blackwall.
