BOTH ARE GOODYEAR TUBES 
OODYEAR’S ability to build tubes that 
last long and hold air unfailingly is 
dramatically related to the fact that Good¬ 
year is also a successful manufacturer of 
balloons and dirigibles. 
There is sound basis for such assertion. Both 
tubes and gas bags present problems of 
inflation. 
For nine years, Goodyear has pioneered the 
furthering of aeronautics in this country. 
In constructing these giant gas bags the 
problem of inflation is exceedingly complex. 
For the gas of the balloon is more elusive 
than air; harder to hold within rubber. 
But it has been conclusively established that 
stout, light fabric, impregnated with rubber 
and built up layer-upon-layer> forms the most 
practical container for this elusive gas. 
Is it not quite logical, therefore, that this 
same built-up principle of construction should 
be successfully applied to tubes whose sole 
function it is to hold air? 
Goodyear Heavy Tourist Tubes are built on 
this principle and their valve-patch is vulcan - 
ized-in . Built up as they are with several 
plies of pure gum, they are the best air 
containers we know of. 
There are thousands of passenger-car owners 
who use Heavy Tourist Tubes exclusively, 
gladly paying the slightly added cost in the 
firm belief that they thus protect and get 
more mileage from their tires. 
More Goodyear Tubes are used than any 
other kind.
