Nice try but it is a documented fact that during the time these aircraft were made "carbone black" was not being used in the rubber. You will see the same if you look at automobile tires from the same period. You really should find another crusade.

Blimps, whitewalls and radials -- How the tire industry developed

By Richard A. Wright

Akron, Ohio, was not only the tire and rubber capital of the United States through much of the 20th Century, it was also the blimp-making capital, a result of a Goodyear Tire & Rubber Co. promotion, the Goodyear Blimp. . .

A picture of the first Buick built in Flint shows an open buckboard vehicle that looks more like a horse-drawn wagon than a car, except that it has white rubber balloon tires on it. Not whitewalls, all white. And the tire is smooth, no tread.

Most of the early tires were white, the natural color of rubber. Some were tinted with a pigment and were light gray or tan or beige. But by World War I, they were all black. They were black because tire manufacturers began adding carbon black ash to the rubber recipe to enhance toughness and wearability.

OTOH I think you have neglected to do the same to others showing obviously light tires. End of the Pis*$#% contest on my part. Have Fun,

"They were black because tire manufacturers began adding carbon black ash to the rubber recipe to enhance toughness and wearability."

Correct! We are so accustomed to see tires as "black" that when, during early '70 (IIRC ) someone attempted to sell colored tires (technology has improved and carbon black ash in no more really needed) he failed at all!

Anyway, I think many tires shown in EV very fine photos were really of light color. Notwithstanding addition of carbon black ash became practice "by WWI" (it may mean "during"), I wouldn't exclude some manufacturer could still make uncolored rubber tires.
