FIRESTONE TIRES POWERFUL FACTOR
 TRUCK MOVEMENT

 The F'irestone Cushion Electric tire and the Firestone Special Electric tire are two other types which merit at tention in the same general class of service as the clincher cushion.
 If you are using one or more light weight trucks. let the Firestone man study your conditions and recommend accordingly.
 Notched Tread Continuous Base Tires
 Firestone builders are justly proud of having designed and built the first notched tread continuous base trucX tire
 The distinctive feature of this tire is that it overcomes the difficulty pre- scented by the traction wave" or the problem of rubber displacement under a heavy load. In this construction the rubber has a chance to spread in the notches without the displacement be- ing felt clear down through the tread at the base of the tire itself. The notches also afford more angles of grip on the road which is extra skid protec- tion The notches allow the blocks to sink down through mud or slush to find firm grip and sure traction.
 This notched tread tire must not be confused with what is commonly called the individual block tire. The ordinary block tire solves the traction wave problem, but presents other difficulties equally destructive. The ordinary 1 block is held to the wheel individually by steel clamping bands; consequently there is no continuous rubber base to absorb and evenly distribute the shocks. strains and crushing jolts. In the ordinary block type there is constant tendency of the tire to teal and cut and to loosen where the meta | plate holds it to the rim. Whereas ir ! the Firestone notched tread the con l tlnuous cushion is there at the base to | absorb and distribute shcks and equal ize the strains, assuring a uniform wear throughout the life of the tire. | ! is argued that when one of the indi. vidual blocks does tear out, another on, can be replaced, without buying a new tire. But why buy any part of a tir, twice. particularly when the new par you buy must be largely cut away ant wasted to match down with the otheI worn blocks? You cant lose bloci ObA Oi llit [ II tStOlit IL IS as HluC0 or unit in construction and in wear as any l continuous tread.

 Removable Equipment
 Seeing the necessity for removable equipment in out of the way places and realizing the advantages of it un 1 der certain conditions everywhere r'irestone engineers were the first |, solve the problm.
 The immediate demand following tn introduction of his FireStonc inyen tion owed how greatly the need wa felt. Further proof is found in tn number of limitations that were 500 offered.
 Unfortunately. all other efforts wer so clumsy. so impra ctical. faulty in de sign ani weak in construction tha those who tried them now hesitate t try any removable equipment.
 We can only say to such operator that in justice to themselves the should question tho users of Fireston removable equipment before passin judgment on the removable idea.
 For many operators there is too muc at stake in favor of the removabl equipment for them to sacrifice thes advantages. which are offered fully an
