Most likely gears.. mine didnt have any codes to put in if I had different size tires/wheels... It only gave info on what code to put in if I had whatever gears.

It should say SpeedCal on it... does it not?

Yes. Raise the back of car, make a mark on the driveshaft, spin tires 1 revolution, count how many times the driveshaft turns.For example, 3 1/4 turns = 3.27`s---3 1/2 turns = 3.55`s--- 3 3/4 turns = 3.73`s---4 turns = 4.10`s---- etc.
