They will be standard truck wheel: 22.5 inch diameter with 295mm or 11 inch wide tyres. Steer tyres might be slightly wider. The wheels would look normal size on the mosore common short wheelbase day-cab prime mover.
My Input: The first truck sounds like it could be a DD 6V53 (it'd be a 4-71 if it were up to me), while the 2 Big Macks are certainly large displacement V8 engines.
Thats a pretty tidy LTL there and the 950 isnt too bad either. 😆 Single drive International reminds of going Perth to Tom Price in the 70's in an old Dodge D2f, Petrol V8, single drive, tandem trailer loaded up with Caterpillar parts for the mine there. Most of the trip was on dirt roads then and sleep on the ground next to the truck or on the load if you had a good tarped up load in those days. Campfires with tin food and spuds in the toolbox to cook in the fire, the good old days 🤣🤣🤣🤣
