I've noticed a few comments about over-inflating tires and wish to offer this:
In 1973, I bought a brand new set of G78-15 tires (which at that time were the modern replacement for the factory original 670-710X15 tires). The G78-15 tires are wider than the original tires causing the car to be harder to steer, so I inflated the two front tires to the maximum recommended pressure indicated on the side of the tires. Two days later, I came back from a trip on the highway which heated up the tires and expanded the air in the tires. I Parked, got out, and just as I walked in the house I heard a LOUD explosion behind me. One of the front tires blew to smitherines (inflated to the exact recommended pressure). G78-15 are bias ply tires, but much narrower than radials. I would think that the expansion due to heat would be worse for radials since they hold more air volume.
Ever since that happened, I have never inflated a tire up to the maximum recommended pressure.
