PLS rims

[123mack]

Is there anyone who could give me some measurements of a PLS rim? I need: inner diameter, diameter of center hole, lug spacing and lug circle diameter. I've measured HEMMTT rims and they won't fit. The lug spacing on a HEMMTT rim is 3.5" and on a M123 it's 4.00" I am thinking of converting my 10 ton to singles as good used 14.00x24s are hard to find, and I can get 16.00x20s with 90% tread at a good price.

well the LHS and the PLS are the same thing.. just one more axle. So it not going to work on your 10 ton. If you want rims I bet I can get new ones but there going to be in the 700 ish range. I know the people who make them for the military.

( I drive LHS's and PLS's for the army)

O.K I saw in an older thread someone said they were different. Oh well, the search continues for something to fit.

boy not that I have seen...I think they may be talking about the flat rack trailer. that takes some odd ball size rim

PLS and HEMTT look the same, but are different chassis.....

Stazworks makes great rims for offroading but I would never use them on a heavy truck. I don't think they are DOT approved either.

Correct me if I am wrong, but aren't the wheels on the M123 24" because 20" wheels won't fit over the brake drums?
I realize 24" rubber was more suited to the super-heavy loads encountered during the 1950's and 60's, but the drums on the M123's are huge!

HEMTT and PLS wheels are different bolt patterns.

HEMTT is the common 10x11.5" bolt circle with 8.75" center hole.

PLS is the larger 10x13.25" bolt circle with 11" center hole.

PLS truck and trailer take different rims, but the bolt pattern is the same.

I replaced the 24" wheels on my M919 with 20" HEMTT wheels and had minimal clearance issues on the front drum. I haven't measured a 10 ton, but it might be possible to run 20" wheels with a little machining.

The issue of fitting the rims over the drums is why I need the I.D. of the rims. I first got the idea of singles from a photo in p381 of Fred Crismons' book "U.S. Military Wheeled Vehicles". In the photo is shown a M123 with singles on the rear axles , and standard 24" rims on the front. It could be an illusion, but the rear rims appear smaller in diameter. BTW, my M123 is a gasser made in June 1956.

The brake drums on the M123 are 18" Dia. the same as a 5 ton which means a 20" wheel will work, the problem is finding the correct bolt pattern which is 13 1/4 as I have been thinking about ways of doing this myself. But I don't want to single out my truck I would like to keep it with the duals. Let me know how it works out for you M123 Mack. Also still looking for those pictures you were going to PM me of your truck.
Thank you David
