Theoretically, you should be able to. In Arizona, the only bikes not allowed on a rack are ones with motors. Tire clearance shouldn't be an issue, since they accommodate wider mountain bike tires. Only concern I'd have would be the fender clearance.
Arizona buses have a sort of foam cover over the wheel latch, so I'm assuming it shouldn't be a problem with how it affects your fenders.
Have you looked on the local bus website to see if you can find more info on fit requirements/capacity? Also, are you comfortable lifting your bike? Looks like it would be more than 30lbs in my estimate.
