More tire tech (with questions)

[gimpyrobb]

I recently was asked how a 14.50r20 was made to fit an MPT rim, but a 15.5r20 was not. I wasn't sure so I did some searching. According to this list:
Army Military Tires
Only when the tire size has the "0" in it, is that tire meant for MPT rims. I know it lists the 12.50 and not the 14.50, but this is what I found on a search.

My question is, am I thinking correctly about that

I think 12.50 in that particular list actually is a typo... If you search other MPT tire manufacturer catalogs you will always find them XX.5RXX or XX.5-XX (no cero following the five), or their more recent metric equivalents XXX/X0RXX or XXX/X0-XX (Example: 14.5R20 = 365/80R20)

As far as I know all MPT-style tires are marked accordingly and can be easily identified by their raised letters on the sidewall. If those 3 letters cannot be found anywhere, that tire is something else but not a MPT. Best example: 15.5/80R20

I'm guessing they mean Multi Purpose Tire, see the PDF:

Multipurpose Radial Tire

Good call on the 15.50 example G- A lot of guys forget about them. Same size as 395 XML but with the typical XL pattern and a bit heavier.

I'm guessing they mean Multi Purpose Tire......

Correct! .... for both types, radial AND cross-ply.
