Spark Plug change

Howstuffworks "Why don't they use normal air in race car tires?"

Many race car teams use nitrogen instead of air in their tires because nitrogen has a much more consistent rate of expansion and contraction compared to the usual air. Often, a half pound of pressure will radically affect traction and handling. With track and tire temperatures varying over the duration of a race, the consistency of nitrogen is needed.
Nitrogen pressure is more consistent than normal air pressure, because air typically contains varying amounts of moisture due to changes in the relative humidity on race day. Water causes air to be inconsistent in its rate of expansion and contraction. So, a humid race in the southeast United States or a dry race in the desert western United States could make for unpredictable tire pressures if "dry" nitrogen were not used.

Nitrogen is also used in the high-pressure tires on large and small aircraft.

im putting nitrogen in my mini van tires now...very cool

Maybe as the tire heats up and raises the vapor pressure of the water, more water occupies part of the gaseous state and takes up space, resulting in a higher pressure exerted on the tire walls? . . . or something.

So my guess was pretty accurate. Due to the varying amounts of relative humidity around the country, they use nitrogen to make their tires more predictable in terms of expansion due to heating on the course.

As you probably found out..the hardest part is lining up your plastic when you changed the spark plugs. In York here the dealer charges 25 bucks a spark plug. They did that once Now I just change them myself.

Go to the closest hotel and talk to the rep at the front desk, explain what just happened and ask them for your prize.


lol ... yup, seems like you may have been accurate.
