I have an OOOOLD Lester 6:00 X 16 for a spare. It has raised lettering, "NOT TO BE USED ON CARS MANUFACTURED AFTER 1948"
It is smooth, supple, beautiful beads, about 2/3 tread left! It looks like a 6 months old tire. SEE, them bastards COULD make us some GOOD tires, if they were willing to do it!!!
Just for fun, I'll try mounting it TUBELESS & SEE IF IT WILL HOLD AIR. (Yes, I have a new tube for it, just in case??)
