Re: Darn Tire Pressure sensors
 
I will have to agree!

There was a good discussion on another group about this and I believe
the consensus was that 'race' cars use the nitrogen tanks to fill tires
because it is the cheapest and easiest to get. Compressed air
apparently is an unusual gas to sell in bulk tanks.

Re: Darn Tire Pressure sensors
 
Back in my flying days, we had both T-37s and T-38s on the line. The
Tweet had (relatively) low pressure tires while the 38 used skinny, high
pressure rubber. The low pressure ones used plain old air, the high
pressure ones got nitrogen. The maintenance manuals gave the reasons for
the N2 for the 38 as less degradation of the rubber at the pressure and
high temps we ran in those plus safety if one blew after heavy braking -
less support for the ensuing fire. I doubt my Jeep could reach the rolling
speeds of the T-38 (typically 165 kts or so for takeoff, max 240 kts
landing) if I drove it off a cliff while the 100/85 kt speeds of the T-37
are (theoretically) possible - air should be good enough. There is some
reasonable argument for using N2 in a spare for the rubber life - but
nothing persuasive.

Re: Darn Tire Pressure sensors
 
Back in my flying days, we had both T-37s and T-38s on the line. The
Tweet had (relatively) low pressure tires while the 38 used skinny, high
pressure rubber. The low pressure ones used plain old air, the high
pressure ones got nitrogen. The maintenance manuals gave the reasons for
the N2 for the 38 as less degradation of the rubber at the pressure and
high temps we ran in those plus safety if one blew after heavy braking -
less support for the ensuing fire. I doubt my Jeep could reach the rolling
speeds of the T-38 (typically 165 kts or so for takeoff, max 240 kts
landing) if I drove it off a cliff while the 100/85 kt speeds of the T-37
are (theoretically) possible - air should be good enough. There is some
reasonable argument for using N2 in a spare for the rubber life - but
nothing persuasive.
