The only people I know that can get away with it are trash trucks that run the big 385 or wider front tires and don't go over about 50 mph.
I'm sure they're even more strict on transportation vehicles. Hell, you have to have more safety clearance/endorsements to drive 15+ people than to haul a nuke...just about.
Shoot, as long as it looks like a good vulcanizing job and it has good lines, it'll probably survive fairly well. Keep a check on the air pressure so they don't get hot, that's about all I would worry about. I'm definitely curious to see how many (paved) miles you can get on them too.
