| The First and Only Demountable Cushion Element for Motor Trucks YOU can now rid yourself of impractical and wasteful giant pneumatic tires and regain all the advantages of solid tires, plus the added benefits of greater resiliency. You can do this without wheel work and without taking the truck out of service. You can do it with the ordinary truck tools. Four wheels can be applied by one man in less than the time required to change one pneumatic. Simply jack up the truck, remove the pneumatic and rim and slip on the Morand Demountable Cushion Element and solid tire, tighten the lugs and drive away. No delay. No shop charges. No tie-up expense. "Back to Solids" say the Experienced Pneumatics on trucks, as a rule, have proved commercially a failure. Many truck owners have found the experiment an expensive one and are eagerly seeking relief. They have rebelled against delays and the expense and risk of blowouts. The argument that drew them to giant pneumatics has been demonstrated unsound. The results they sought were not produced. The Morand Demountable provides permanent resiliency and cushions the truck against shocks and vibration. In addition to this feature, they deliver greater mileage, economy of operation, and safety. It is the first and only demountable cushion element. Solid tires are troubleproof from the day they are put into service until they are worn out. They never require change. They provide a thick cushion of live rubber between the road and load. The "Why" of Morand Demountables Note the cutaway illustration showing the Morand Demountable Element. See how thoroughly practical it is. Compare its advantages. The cushion of live rubber is bolted top and bottom between steel channels. In action, this cushion provides equal distribution of resiliency throughout the entire circumference of the wheel. No one portion receives the entire burden. | ||
