bias ply tire pressures

[Ol' Ron]

I find that when switching tires from the factory recommended ones to an off size it best to chalk them, to determine the correct pressure. Find an empty parking lot and add some chalk to the tires and dive around the building and check the chalk, you'll see the ware pattern and adjust accordingly. Rumble seat would run them alittle soft to improve the ride. Radials are really a great improvement over the old Bias ply tires. There are allot of good things out there that can improve the performance, economy and safety of our old cars.
