Fuel Tankers: Replacing Split-Ring Rims

BLUF: When no longer serviceable, split-ring rims and their tires need to be converted on M967A1, M967A1P1 and M969A1/A1P1/A2P1 fuel tankers.

On Page 17 of PS 664 (Mar 08), we told units with M967A1, M967A1P1, M969A1,M969A1P1, M969A2 and M969A2P1 fuel tankers that the split-ring rims and tires were obsolete and needed to be switched with tubeless tires and a one-piece wheel assembly. We updated that article a few years later on Page 13 of PS 793 (Dec 18) with some NSN corrections.
If your unit has any of these fuel tanker models and either the tires or split-ring rims are no longer serviceable, including the spare tire, you’ll need to convert them to the one-piece wheel assembly, NSN 2530-01-506-4125.
Just make sure to replace all of the wheel assemblies at the same time to prevent improper wear. That’s a total of nine (9) one-piece wheel assemblies. The wheel assembly includes the parts in the table below.
Item NSN
Wheel, 22.50-in, tubeless, stud-piloted 2530-01-510-6121
Tire, 11.00 x 22.50-in
(load range “G”)
Valve stem 2640-00-555-2824
Valve extension, 5-in 2640-00-338-2705

Here’s a tip! When you’re converting the split-ring rims, don’t throw away the lug nuts. That’s because the inner and outer lug nuts are the same ones used with the one-piece wheel assembly.

Note that this article doesn’t apply to the M967A2, M967A2P1, M969A3, M969A3P1, M1062 or M1062P1 fuel tankers because they never had split-ring rims.
