Larry and Diane, I tried the Sam's club in Houston, and was told they did not have 315's. Apparently, the person I talked to must have been filling in in the Tire department from fruits and veggies that day, because you were able to get tires from Sam's. The Continentals I bought were $589.95 each, mounted, balanced (or with equal which I chose) and taxes. I bought them at Southern Tire Mart, who have some 55 branches across the southern states and Nevada, which I found to be somewhat comforting, in case I need a tire replaced. I also spoke with Beasley Tire in Houston. Very nice and helpful, but were more expensive than Southern Tire.
Now to be able to find time to give the tires a workout...and see how they perform....so off to the Oysterfest in a few weeks. Look forward to seeing everyone there!
