From memory, no.
They seem to match the design on some other off the shelf truck trailer stuff i picked up cheap.
The gov mansion limo has the same wheels
Actually looking at this pic
Has jogged my memory
I bought two truck sets i saw at the local supermarket because the trucks looked in scale.
Each set had a truck, two trailers, a helicopter a tank and a jeep.
The jeeps were not in the same scale as everything else, so i took the wheels from those, and built the lift truck on top of them
One of the choppers has "china" on its belly. so in all likelyhood its just some no name brand.
