RE: Tire Size/Speedo Calibration
20" tires should be around 28.5 to 29+/- tall.
Measure the tire then plug in the flashpack and select Select Performance Tuning/Change Setup/Options/Tire Size and hit plus until you reach your your tire size, it increments by 1/4". Save and Exit then select Program Vehical.
