What is an Ideal Tyre?
If, as an experienced and unbiassed motorist, you were asked to enumerate the qualities essential in a Motor Tyre, they would most probably be:
Quality & Durability The rubber used is the finest possible for the purpose, toughened under a special process, and affording remarkable resistance to flints, nails and abrasive road surfaces. The “casing” is of finest closely-woven Egyptian cotton. Seven layers of this fabric go to make up the casing; between each layer an appreciable quantity of rubber is cleverly imposed integrally, affording great strength to the foundation, minimising the possibility of “rotting” and affording marked resiliency to the tyre when in use.
Efficiency The design of the “Shell” patent groove is obviously far ahead of the hitherto most popular plain groove, for the “Shell,” unlike the plain groove, is designed to grip ALL ways without loss of engine-power through suction or friction; while its wide open-ended grooves keep it cooler than even a plain tread.
Economy Their remarkably low price is arrived at by the simple addition of a reasonable working profit to the actual cost of manufacture—nothing more. The buyer of “Shell” Tyres thus gets value for money every time. The prices of “Shell” Tyres will be found about 25% below those of any other high-grade tyre. Whatever the prices ruling on the rubber market, or at whatever price “Shell” Tyres may be, there will positively be no lowering of the “Shell” high standard of quality. On the other hand, Harrods’ constant endeavour will be its improvement in every possible respect.
