Chatting with a Mustang tire service guy, busy sucking air out of lots
of Mustang tires with a shop vac, curiosity got the better of me.
Said he fitted a new set of tires each race day to each of the 5 vintage
Mustangs under his wing. After sucking the air out, he replaced it with
Nitrogen, because "using Nitrogen to inflate the tires, the tire
pressure increase whem hot was only 20% of tire pressure increase using
air"
Have some laws of physics been repealed?, or perhaps they don't work at
weekends at race tracks, or is there really something going on here?
