Bob,
Like it has been said, you car probably came with Firestone, US Royal or maybe Goodyear. Coker sells the Firestone and US Royal but 750 x 14 is the largest they have in 14 inch. You probably want 8oox14 so with Coker you have to go with BF Goodrich to get the 800 tire.
I use Goodyear tires on my stuff because they are available in 800x14 and the repo Goodyear tires are about an inch taller than the B F G's. Amy way you go you can figure about 200 per tire, maybe a liitle more.
The Goodyear tires are available from Universal Tire in Hershey.
