In ten minutesthe tires had been expanded .08 in. in diameter, and the lampswere removed. In five minutes more the tire had been swung. 1 Fig. I. the tread makes it necessary that the heat should be carried byconnection to the farther corners, so that the probabilities arethat the center of the inner surface of the tire Is heated morerapidly than the corners or the flange, and, consequently, thetire remains for a longer time in contact with the center, which,therefore, receives a greater portion of heat.

Thethird test the lamps were burning for 12 minutes, and 2i min-utes more were required for the removal of the tire.
