28 lbs on all 4 tires?? Ford calls for different pressures for front and rear.

Radials and bias ply tires require different inflation pressures because they are made differently. A bias ply tire has a much stiffer sidewall than a radial tire. In a radial tire the cords run in parallel across the tire at a 90 degree angle to the bead. The cords on a bias ply cross at an angle to each other as they run cross the tire. The triangulation of the bias ply cords stiffens the tire carcass. That is why the radials require a higher inflation pressure, it is to compensate for the flexibility of the sidewall. Matt

Steve Lee, I am sorry, but it sounds like you got an empty barrel when you called Coker. I would never run 34lbs of pressure in the bias ply tires of a 1950 Ford. Like Steve Hansen said, you will wear out the center of the tire and have poor traction when trying to stop. I like to keep my tires on the hard side to reduce heat build up. The owner's manual for my 40 Merc says 26Lbs all around and I keep 28Lbs all around. My Lincoln owners manual says 26 in the front and 22 in the rear, again I add 2lbs to each of them. These are all tube type tires, which tend to have a higher heat buildup than tubeless tires. The tread pattern and size markings are different between radial and bias ply tires. Search for your size on Coker's website and you should be able to see the difference.
Tom

Tom, I just phoned Coker and the guy said that radials have an R in the size between 670-15, like 670 R 1 5. He also said that mine are then bias,and to run 34 lbs. in all (4). How say you?

Tom, my big question is: How can I tell radials from bias???? And, would you run the same pressure(s) on all (4), or more in the fronts Ford says?????

I always ran 28 lbs on bias tires 670.15 on my 50. When I switched over to radials I found it necessary to run about 34 lbs to avoid a wandering effect on the road.
