I have set the SpeedCal for 3.27 to 3.73 gear change.. but I couldn't find anything for tire sizes. Any idea?

255/60/15 are 27.04 diameter while a stock 245/45/17 is 25.68 diameter.
If I remember my jr. high school math correctly
27.04 3.73------ X ----
25.68 A25.68*3.73=27.04*A
95.79=27.04*A 95.79/27.04=A 3.54=ASo in otherword set it for 3.55 gears and you'll be just fine.

kk... I didn't understand any of that.. but thanks MadDAWG ;).

that maybe, but Mr. Cooper is smiling lol
Actually its a simple ratio tall tire * low gear = short tire * higher gear. Since we know 3 of the 4 values its simple to come up with the 4th.
