    ..... so they gripped on the curves better, do you think they would be accused of cheating or something weird like that? :confused:












    ..... or not? :red

    ok fine :red .... how about if a person actually ran MORE than the recommended air pressure in their car tires than in order to reduce rolling resistance thus increasing the gas mileage. Do you think oil producing tycoons would have a big problem with them because they are cheating and using less fuel, thus cutting into the oil industry's profits?

    Why or why not? Please explain your answer in metric. Not like above^ :waiting

    It depends. Does the team owner have the commissioner as a sock puppet? Then it's just haters and jealousness.

    if it was a rule that the tires had to be within a certain pressure then yeah it would be cheating. People seems to think if a rule is stupid that means they don't have to follow it

    more pressure would result in less adhesion..actually a detriment. IMHO of course.:nono

    If that happened, they'd probably go around in circles! Ba-doom! Thank you ladies and gent's. I'll be here all week. Try the veal.

    Wasn't a Formula 1 race car disqualified after winning when it was discovered that it was 1/4" over the legal width?

    First of all, Indy cars don't use gasoline, they started using Methanol in 1964. They have since converted to E100 Ethanol or 98% Ethanol/2% gasoline, which produces a more visible flame and a bit of smoke when it burns- this is helpful when the cars crash and makes it possible to save drivers, rather than assume they're out of danger because nothing is visible.

    Second, the speed, degree of banking in the turns, tread compound/tire structure, roadway composition/condition, track temperature and level of contamination (among other factors) determine the needed inflation pressure. Deflation makes them stick better (to a point), but it weakens the sidewalls, which makes handling when the car's Center of Gravity changes and it increases rolling friction but over-inflating makes it prone to breaking traction. If the pressure is very high, the direction of the force needed to overcome the friction between the tire and track doesn't matter as much.

    Racing teams have been using Nitrogen for a long time, because it's affected less by temperature changes, and this would have eliminated the under-inflation cause I heard this morning, which was "the balls were inflated and taken outside". However, inflating the balls in 70 degrees F and taking them to the reported air temperature of 50 degrees F wouldn't make a 16% change in internal pressure.

    If someone drives a car over the highway on a trip and increases the pressure, they can save gas but it's not recommended because hitting a bump can cause tires to fail. If they're on an absolutely smooth/flat/clean/dry road with no hard cornering, it's relatively safe.

    You mean like the France family that runs NASCAR and owns a track?
    That's like Rodger Goodall owning a stadium in Las Vegas and holding the Super Bowl there every year.

    And it is.
    There is a minimum allowed pressure in race car tires. That's checked as the cars sit on the grid. In Nascar, there are some things allowed. Cooling fans that blow air on the tire to cool it can be switched off to raise pressure.

    If low tires at Nascar had anything to do with the New England Patriots winning, It would be considered cheating!

    Talking about football related cheating is only marginally more interesting than sitting through a game of Line Change.
