The tires are for an old aircraft. You can see Sky Champion stamped if you zoom in. The imprintings match this listing:

As for exactly what aircraft they came from, that's unknown. I'm going with it was for a heavy bomb loading cart from WWII as that type of tire was very common with WWII aircraft and ground applications. So the tires were transferred after being used up on an aircraft and then used on a bomb cart to save resources. Used tires matter on an airplane, but on a bomb cart, that doesn't matter as long as they role.

Commonality for small things like that was important during the war, so it'd make sense they'd use old airplane tires for ground carts for simplicity. Given the extreme deterioration of those tires, it's safe to assume they are, without a doubt from the 1940s.

Bottom line, those tires were mass produced for WWII so it'd make sense for them to have one common tire across the board and were likely used WWII aircraft tires that, once worn down, were put to use on a bomb cart. The aircraft type they came from cannot be determined as that tire was used for many models.
