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.

69,

Go to tirerack.com and look up your exact tire and get the specs for it. They will have it there. It's an excellent site for tire and wheel information.
