THE NEW DUNLOP TYRE.
As the modern motor car becomes faster, so it calls for a corresponding development in its various components. Take
tyres for example. Higher speeds, fiercer acceleration, more powerful braking, combined With the demand for lighter steering, smooth travel and silence, present some knotty problems for the tyre designer.
The Dunlop Company has always been in the forefront of research work, both for racing and touring, and their answer to the above problems lies in the introduction of an entirely new tyre, called the Dunlop ” 90 ” It does not super sede the triplestud tyre, but is alternative to it, and available in the wired type sizes in both Fort and Standard qualities.
Section for section, the tread contact of the ” 90 “‘ is greater than that of the triple-stud type. Its sharp edges bite into the road surfaces and resist any tendency to side slip when cornering, while rows of deep lateral studs, and the notches in the linked central studs check forward slide. The ” 90 ” is designed to retain its non-skid efficiency until the tread is worn. smooth.
In spite of its firm grip on the road, the Dunlop ” 90 ” makes. steering easier and more responsive. In. braking, too, it reacts efficiently and evenly.
A remarkable asset of the new Dunlop tyre is its silence, even at high speeds. Noise occurs only when cornering at speed, indicating that the tyre is holding the road with increased tenacity. The first ” 90 ” was produced from a miniature manufacturing plant attached to the laboratories at Fort Dunlop, and the finished tyre was put through a series of the severest tests including a reproduction of rough road conditions staged on a rotary testing machine in the Test House,
and the dropping upon it from heights up to 20 feet of a knife edge weighted up to 2,850 lbs.
