Basically, that's how ALL tires - for automobiles, trucks, and
tractors - had their size indicated, long before the present globally
used metric system (P-400/50R8 might closely express that tractor tire
size in metric). A passenger tire might be P-215/65R-16. Light
Truck: LT-235/70-R17.

It seems that tractors have hung on to the old designation system.
