It would presumably have tires appropriate to the speed as well, but these are really irrelevant questions. The real question is why they were driving like that in the first place? Irrespective of party affiliation, I really wonder what justifies a governer tooling about at ~25 mph above the posted limit. I mean, what's the emergency? Gosh, I've got to get somewhere and ... govern??? An ambulance with a critical patient, sure. A governeror's Suburban -- ridiculous. I wonder what would have happened to an average Joe caught doing this speed in the same place? Silly question, of course. NOTE: this is NOT meant as a political comment; both parties "leaders" are guilty of such arrogant foolishness.
I heard on the news someone in LE was planning to issue the governor a ticket for not wearing a belt. Good. Give him one for speeding too, since he was undoubtedly the "captain of the ship" and is responsible for that too.
