" From: <mail@xxxxxxxxxxxx> " " Does anyone have experience running nitrogen in tires? " Indy cars use them for less rolling resistance, cooler " temps and a couple other advantages. I heard the big " rigs are starting to use the stuff too. Any real world " advantage as far as car usage.....Russ reducing oxidation certainly makes sense, but the only thing i've ever heard is that dry nitrogen has less pressure change from cold to hot than air. perhaps it's the humidity effect. ________________________________________________________________________ Andrew Hay the genius nature internet rambler is to see what all have seen adh@xxxxxxxxxxxxxxxxx and think what none thought
