"Unless the room the tire is in is filled with Nitrogen"
Well we were all giggling a lot while the instalation was performed so perhaps it was. No charge for it appeared on the bill so I think it was "no charge". The shop asked me to stop by at least once a month so they could top off if necessary so if I follow their advise I'll never need to top up with air.
Giggling? If the room had been filled with Nitrogen you wouldn't be giggling for long...
