Straight side tires
 

This tire gage has been in dads toolbox for years
and I just noticed it had writing all over it.

It says "supplied for use with Goodyear straight side tires".

Can someone explain what straight side tires were ???

straight side tires--possibly directional marked with arrow on sidewall. i remember that for instance tires mounted on motorcycles to channel water from tread. Tom.

Quote from Goodyear website:
The straight-side tire (1901)

In 1901, Goodyear created the first straight-side tire. The major innovation in this new tire design was the addition of a braided piano wire to the tire's bead. The wire was cured into the bead, which held the tire onto the rim with a complicated set of locks. Since the tire didn't curve in to fit the rim, as its forerunner did, it could hold 10 percent more compressed air, providing a more comfortable ride and improving traction. Goodyear also adopted the Wingfoot trademark to advertise it; a symbol of the company's commitment to innovation and quality, and one that is still used today.
