Roland, better stock up on that fresh Alpine air, as the rare Alpine air lilies that make that air on on the way to extinction. Yes, you can probably change over to the somewhat less pure air of the Transylvanian air lily, harvested from a very small corner of the Transylvanian Alps in the remote Trans-Dniepr Region, but you will see some minor handling glitches. For instance, the tendency of the tire to wander toward fresh road kill, or swerve away from Garlic.... OH wait, no that's the Vampire Lily, sorry, a bit rusty on my horticulture....
