Please help me copy this tire combo. What is it?

[Morse]

I acquired my grandfathers truck not long ago. I wanted to build it in a way that my father would like to see it, rather than by my own choice. After showing my father many pictures, this is what he chose for his fathers truck to look like. Therefore, I'm copying this look for my grandfathers truck. If anyone could shed some light on this tire size combination, I would greatly appreciate it. Vendors, feel free to contact me if you can get them.
All help is very appreciated.
