The best wide whitewall tires I have ever had on any car (I've had crappy Cokers, too) are Diamondback Auburn Deluxe.

They are radials that look like bias ply tires. These were the old sidewall design. The current ones look more like the pie crust bias plies.

They are the best handling tires I've ever had on this car.

Here's a link to the 750x16 Auburn Deluxe
