Tire cal. for my tires?
 

I was just wondering what anyones else with a set of 285/65/18s and 3.73s are running their calibration codes at. I cant remember the actual # that I came up with (with the formula) but it made my speedo off like 10mph. I currently am running it at 2400 and had my wife follow me up to 75ish while talking on the phone with her to see waht instantly she was doing and we were maybe 1 or 2 mph off.

Just wondering?

2496mm
Thats 2600-104
104 is .04 or 4% squish
