This is the headline on AOL right now,,,,,,
"2 people killed in reported tire explosion at Delta facility in Atlanta airport"
Why does an airplane tire have so much pressure in it??
NASA did tests back in the 1960's,
They found that a tire would hydroplane on water at ten times the square root of the tire pressure.
For a car tire, if you have 25 psi (square root = 5) , then the maximum safe speed is 50 MPH
If you want to go 60MPH in the rain, you better have 36 PSI in the tires.
If you want to go 70MPH in the rain, you need to have 49 PSI in the tires.
(I keep 60 PSI in the tires on my Silverado)
You need to have this much pressure to "push through" the water, so that the tire will have traction,
Less pressure, the tire will press with less pressure, the water can lift the tire.
How fast is a plane going when it touches down?? BIG number,, that means the tires need a BIG pressure,
Think about that,, the next time it is raining,,
and you have not checked the tire pressure in your tires in 18 months,,,,,,
SLOW DOWN!!
