Re: Speedometer

New tire size / old tire size x the speed your speedometer says = actual speed.

That's how I figure mine. I just do the math while I drive, 90% efficient, so 30 is 27, 50 is 45, and so and and so forth. Of course you have to factor in gear changes too. And yes, it would be much easier to get a truspeed, but that costs money. [img]images/graemlins/smile.gif[/img]
