I've noticed that my IS-F with the stock wheels and tires seems to read about 1-2 mph low. Is that pretty typical?

I'm basing this on the fact that two independent speed trailers that show your speed both showed my indicated speed between 1 and 2 mph too high.

I guess I could pace my wife's car and see if it confirms or denies this. I guess I'd rather have it read low than high :)
