ERE is a convincing sales point with which the U. S. Tire Dealer is selling many a tire these days—

Visualize the action of a Balloon Tire on the road, and the science of this Royal Cord tread design immediately makes itself clear.

Under load, the entire width of the tread is in contact with the road. So the outside tread blocks have been built up to give a semi-flat contour.

This reduces the flexing action of the tread shoulders, distributing the strain and wear evenly over the entire tread surface. Now note also that the tread blocks are made relatively small.

This is very necessary in a balloon tire. If the tread blocks are made larger, they throw heavy strains on the tire.

The U.S. Royal Cord Balloon Tire is built of latex-treated Web Cord—strong and flexible.

It is accurately balanced. It is scientifically designed for maximum comfort, safety and service life.
