ok speed calibration... no my car isnt off.. or if it is i dont know, but as some of you know i work at a Sheriff'* office in FL, well yesterday we had to get all of our cars calibrated, which of course 99% were off by like 1-2miles... what causes it or can you do anything about it??

Tire wear. New tires don't exactly match OEM tire diameter that it was calibrated for. Or that fact that most factory speedos are not perfect to begin with.

Which is the real reason why some nice cops just let ya go when they see a 10mph difference...lol They are sitting there saying "must be his speedo'* off"

I saw a test Car and Driver did a while back. One of the biggest offenders of bad speedos was BMW. GM was actually on the good side of average.

eeeeewwwwwww.......... People should never have Speedo'* on. ANd the one'* that wear 'em. I don't wanna see 'em off....






sorry. stressful day already. needed to make at least myself laugh

You came pretty darn close to making me laugh........ Darn close.......

tire wear would make a good speeding ticket excuse :P

Except it wouldn't work. Wearing tires makes your tire diameter smaller, so you move LESS with each revolution, hence slower than you think you might be going. Try saying the tires are non stock and act stupid.

"GM was on the good side" hmmm so i was relly doing 110 when i got pulled over the other day. I was kinda hoping my spedometer was off by 55 mph.

That might actually work, if the flirting doesn't work first.
