MRAP / JERRV wheels? no further info though, trying to figure out what they are

[Cowpig]

Hi all - I recently got 5 of these steel wheels for my truck, but they didn't have o-rings or valve stems and the markings stamped on them don't turn up anything on the internet.

the seller says they're MRAP/RG31 cat 1 and MRAP/JERRV wheels NSN #: 2530-01-559-5894, Part #: R0022410


16 Stud 8 Hole Wheel / Rim, 20" inch x 10" inch with 11" inch offset

another seller on ebay says they're actually 'proto-type' wheels that were never used so there isn't a NSN or part number.

any opinions or experience on what o-ring will fit these? the studs are the 15/16" size if that helps - research that i was able to find seems to indicate 7/32" o-rings...but some of the threads on this site indicate go to the next size up anyway to help ensure they'll seal. (I do have some lithium grease I was planning to use on the orings, if i can figure out which ones to buy!)

thanks, Jim



also - I have 5 stryker wheels, the aluminum ones, NOS. same bolt pattern as these steel ones but the offset/backspace was all wrong for my truck (c4500 4x4). Not sure if anyone out there can use these or not, or have any ideas on if i can recenter them for smaller truck (550/5500 truck?)

oops, all the writing was in white ... sorry about that made the change so you can actually read it

also -the only markings stamped on the wheels are as follows:

GW C40001289 S
OW 1923 09-09

and another one has

GW C4000824
OW 1928 07-07

google returns nothing at all on these numbers - guessing they're just gross weight (GW?)code or lot numbers and the date of mfg?

thanks John, I must have messed that up when I was trying to copy and paste the wheel description in

well was hoping someone here knew ... but i have a couple sizes of o-ring and a dual port valve on the way to test fit a tire. i'll post results on both in case anyone else is in this situation with these wheels....

 

[Cowpig]

to close this out in case somebody stumbles across my thread someday...

20" combat o-rings, 1/4" thick (black) and the dual port valves ... drill the hole to 13/16"

the wheel studs are m14 x 1.5 (I wanted a die to chase the threads). Near as i could find... torque them to about 162 ft/lb. mine are holding psi and mounted...
