Tires should be easy. Rims. I dunno. Any 22.5 would work if u wanted to dual it. I bet a 20" would work with a 395 or something to keep it low and still handle weight with the single

The manual states the OEM for the wheels was/is Accuride wheels.
It would be a simple matter of getting the correct hub piloted wheel with the proper backspacing and offset,plus the correct lug pattern and size.
After measuring the wheels on my M322 trailer,I believe the proper wheel is as follows:
Accuride part # 29805 22.5 x 12.25
10 hole on 285.75 mm bolt circle
220 mm bore diameter
5 hand holes
0.63 offset

Mine has JOST mfg corp jacks,I believe they are model # A400 with the drop foot option,I still need to confirm this with Terex/Load King soon.
The rear ramp assist springs are designed to slip over a 2 inch diameter shaft and are 3/4 inch diameter material.
BTW,for anyone missing the steel covers either over the lifting rings on the deck or the rear toolbox the dimensions are as follows:
Front deck lifting ring covers, 12 inch X 16 inch, 1/4 inch thickness checker plate with 2 each 2 inch x 2 inch angle,2 inches long.
Rear toolbox lid, 35 3/4 inches x 21 1/2 inches x 1/8 inch stock thickness,I used 1/4 inch plate for mine,NOTE it has a 3 inch bend at the lower edge for the lock loop.
Rear toolbox lid angle iron, 3 inch x 3 inch x 1/4 inch thickness ,35 3/4 inches long.

Does anyone have a pic of their jacks? I am not sure if they had a gear box or just a handle.
I am tired of using my wrecker to load/unload just the trailer.
You can see that someone walked off with whatever was using to crank the landing legs.

Go to your local heavy truck/trailer parts house,it's pretty much an off the shelf part,there are 2 different lengths though.
I got mine from Fleetpride for about $20.
Does yours have a gear box or a crank/handle?
Mine is missing whatever the M322 came with... my buddies has a gear box.
Putting this here: A400 has an internal gear box. http://www.jostinternational.com/wp-content/uploads/2016/02/SL-TP-001.pdf-Trailer-Parts-Catalog.pdf

Mine has the JOST jack with the internal gearbox.

Yep, so does mine. I have a new gear drive coming and a handle. Will be nice to get the trailer off my wrecker without using the wrecker to lift it.
Also bought the trailer light plug and need to get glad hands for the brakes/air supply...
Mine has the JOST jack but I think they are both from the same side. I had a piece of stainless steel pipe connecting em and one goes up and one goes down. Just got done making my ramps for it the other day. I cut up 4 M931 spare tire systems with the 3/8" 3"x3" angle iron. They are 7' long. and heavy. No springs yet. They aren't bad to walk up.

That is one thing I have noted with these trailers,I actually believe the factory ramps are HEAVIER than the stock ramps that came with the M172A1 lowboy trailers.
Mine does not have the assist springs as of yet(still on order) and I cannot lift the ramps to vertical without the assistance of either the backhoe or wrecker.

Just a 2" shaft spring. 3/4" diameter. Should be able to get it from a trailer parts place like fleetpride.
