My favorite spec is

Tires. . . . . . . . . . . . . . . . . . . . . . . . . Michelin 55/80R-63

Could be a great prank call. I doubt Valley Forge Tire and Auto carries it, but it'd be fun making them check.

(R-63 indicates a radial with 5 foot 3" inner diameter. The 55 specifies tread width, and the 80 is sidewall height as a percentage of the tread width). For normal tires the tread width is in millimeters, but I suspect it's in inches here. So the tire is just over 5 feet inner diameter, just under 5 feet wide, and with a sidewall height of 4 feet. Apparently the current best tire for this truck is a 59/80R63, which is a bit bigger)
