The video of the IL-76 skating on ice got me to thinking about how hard the ice must be and how big the tires were, which led me to this video from National Geographic. They use water now.
The tires on big aircraft are big (about four feet in diameter), but not a lot bigger than they used to be. We had a big, tractor towed chemical sprayer on the orchard and it rolled around on a couple of big aircraft tires. I imagine that the materials used to make these tires have gotten a lot better.
