Wheel Trouble Growing Tire-some - What Brand?

[J.P.G.]

Hello,

Would any of you happen to know what brand and type of tires came on 1946 p-15 Plymouth Deluxe Club Coupes? I am told Plymouth switched to Goodyear supercusions sometime in '47, but I can't find anything about the original make of tires. (I ask because I think the old spare in my car's trunk might be one of the original tires).

Thanks!
