That said I think most if not all airlines require that you deflate your tires.Yes, but it's not a good idea to do so. The tires provide quite a bit of cushioning and protect the wheels from damage. I know the airline is worrying about transporting compressed gasses because of the explosion risk, but really--that's not a hazard with a bicycle tire. It isn't going to explode even if the pressure doubles, and it would cause no problem even if it did.
What do you guys do? Deflate or not deflate? Or maybe reduce the pressure a bit?
