Now that I am upgrading my wheels & tires from 16 inches to 17X9 will I have any problems with my odometer or speedometer. I got 255/50-17 for the front and 275/40-17 for the rear. I have a SCT hand held tunner. So I assume that will handle it if I need to change anything.

 

The tunner will fix any problems that you have. You will need to fix your tire hight (revs per mile).

If you get the correct height tires you need to change nothing, however your front tires are taller then stock and taller then the rears if you dont know that. The wheel speed sensor is in the rear though i do believe so your speedo will still be correct.
