try moving the height setting down .5" at a time until the speedo is dialed in.

Measure the tire height with.a.tape measure subtract .5 enter that number as mikel suggested and go from there up or down .5 at a timetill u get it. My tires are 35.8 inches tall but My height setting is at 33.5 and the Speedo is dead accurate in refrence to my GPS in thedash.
