Which positions this size comes in
Not every size is made for every axle. These are the positions 285/70R19.5 is actually sold in.
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.
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.
DrivePowered axles
The tires that put the engine's torque on the road, usually eight of them in dual pairs on two axles. Deep, blocky lug tread for traction, which is why they are noisier and wear faster than a steer tire. This is the position where a good retread saves real money.
Load index and speed rating
The most common markings on 285/70R19.5 are 146/144K, 146/144L and 146/144M. 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.

265/70R19.5 – The tall 19.5, median $277 against $467 here.
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.
