Yeah the wheel was a shortcut to replicating the one below. At first I thought it was brown but I guess it's a yellow one but with a far bit of hub oil leakage.
Odd roadwheel

As an aside I've found quite a few pics of late Abrams with a lot of odd green replacement parts, gun barrel components, - tube sections and extractors, top mantlet covers along with the usual fenders and wheels.
And a question on the front fenders, are they some sort of ABS or are they sheet metal?
