T HAT rigid adherence to traffic regulations which protects the cautious 
motorist at congested intersections is completed by full equipment 
of Vacuum Cup Tires. 
The deep-purring ” Sound of Safety” of the Vacuum Cup Tread means 
the cups are exercising their famous grip-hold-letgo principle of suction 
on wet, slippery pavements, generating safety every inch of the way. 
Rough country roads 
or smooth city streets 
— they serve as wed 
on one as on the other 
The Vacuum Cup Tread means extra service. It is built of hundreds 
of sturdy Vacuum Cups over an already extra heavy, extra ply founda¬ 
tion, giving safety and service far beyond the limitations of ordinary 
makes of tires, though the purchase price is no more.
