Hmmm
The DoS used stock rims (wheels)
But they'd use whatever fit in, appearnce-wise.
In my viewing, the tires weren't flat.
There's many type of tires used.
Ranged from full rubber, to run-flats, with bands on the inside to allow the truck to drive with no tire air.
Civilian observations, and mis-observations, are how they keep diplomatis safe.
Too many stories to share share here.
One snippet: VP J Bidens's wife wanted to shop while Joe was at the UN in NYC.
In the armored Suburbn, cams looking thru smoked black glass, our cams went into b/w mode too often in the canyons of NYC.
Switching latency became a conversation point 'tween us and DoS.
Safe to say, the US Gov't has some good eqpmt. Leave it there.
