My understanding was that a radial might start cupping in the middle of the tread if the pressure was low unlike the old bias ply tires. As goofy as it sound we always went to a good surface road, spun about 10 feet and looked at the contact patch and adjusted the pressure accordingly. It was easy to see an over inflated tire, it got a little tricky on an under inflated one. Food for thought, Mike
