It's a lot less confusing when you realize (based on your own link) that freight trains do not typically (if ever) have rubber tires, they are general used for passenger rail systems. And while airplanes do have rubber tires, few people would say that the freight is carried on tires when the tires are only used for a tiny percentage of the trip. If pneumatic tires were never invented, airplanes could still exist, they'd land on non-pneumatic tires, skids, or some other method. I think only someone looking for confusion would be confused by someone saying that rail freight and aircraft do not travel on rubber tires.
