I drive my '40 every dry day all year long. I have the Coker Firestone 600X16 bias ply tires now. I had my tires balanced when I put them on and the '40 stock 5" wide rims all showed to be very good. However, every single one of the tires was out of round and at 60 mph to 70 mph they vibrate. I decided to go the radial route and found the tire size I need is 195/80R/16. I found out the hard way the only mass produced tire in that size is made for ELECTRIC CARS ONLY. Very thin tread depth and not rated for mud and snow. If you buy a radial tire they don't have the look the bias ply tire has on the outer edges. Yokahama does make a 195/80R/16 tube less tire, but only makes them on a special order bases for volume purchases. No regular tire store will sell enough of them to meet the order requriements. The only way to get tube less radial tires in the safe and correct size is to work with a specialty tire store. Just start checking around and see what you come up with.
