Re: radar signs
it could be your speedo is off.... or the radar is off... I know that cops use tuning forks to make sure that their radar is on... but if it's consistant... then my guess is it's your speedo.

Re: radar signs
tire size changes gear ratio, and throws off your speedo. I had a programer for my truck i had when i had 20s on it. my speedo was like all crazy before the programer.

Re: radar signs
Don't bigger wheels make the speedo slower or is it the other way around.

Re: radar signs

Re: radar signs
I would say you are correct; however, radar says its 5mph less than what I'm going.

Re: radar signs
wheel size doesnt matter. what matter is the tire size. i forget the formula but basicly you need to figure out the circumference of your tire and then there are sites that will tell you the speedo difference.
that said its probably not your tires making the speedometer inaccurate. its probably just that the stock speedo isnt very good
