Which positions this size comes in
Not every size is made for every axle. These are the positions 245/70R17.5 is actually sold in.
TrailerFree-rolling axles
Free-rolling tires that neither steer nor drive, so they are built for scrub resistance and low rolling resistance rather than grip. They get dragged sideways every time the rig turns tight, and that is what kills them. Cheapest tire per mile of the three positions.
All-positionFits anywhere
A rib tread that is approved for any axle. Common on dump trucks, mixers, buses and anything that does not run enough miles to justify three separate tire programs. It is a compromise: less traction than a drive tire, shorter life than a dedicated trailer tire.
SteerFront axle
The two tires that carry the front axle and do the steering. They wear evenly in ribs rather than blocks, run the highest load per tire on the rig, and are the one position where federal rules ask for more tread: 4/32 inch, against 2/32 for everything else. A steer tire is also the position nobody retreads on a tractor pulling on public roads.
Load index and speed rating
The most common markings on 245/70R17.5 are 143/141J, 143/141K and 136/134M. The pair of numbers is the load index single and dual: the first is what one tire carries on its own, the second what it carries as one of a dual pair, which is always the lower figure. The letter is the speed rating, and on commercial tires it is low by car standards on purpose.

Wheel diameter has to match. A low-profile and a standard-profile tire on the same rim are interchangeable on the wheel but not in rolling circumference, so never mix them across a drive axle.
