The Old Trucker,
The Wheels are new and were specifically designed for the Snow Coach. The computer model tested at 30,000 lbs which is stronger than needed and they won't rust. The tires are also designed for the snow coach. They are a 6 ply with a pressure maximum capacity of 105 psi. They have a recommended pressure of 70 psi but they seem to run well at 50 to 60 psi. The tread design is three rib. The reason for this is to help cool the tire. The smooth tread design would be cheaper to build, but choice was to improve on the application. The bead area is also stronger than competition design with the sidewall more straight up and down. This allows the tire to resist rolling over from side pressure. Xanterra, the company that has the vender contract with Yellowstone Park and runs 28 of the coaches, has been running this tire since 1994. They tell me that it cut replacement cost by 30 percent after two years and got even better as full replacement took place in subsequent years.
