Anyone have a 6" lift with 35's & an edge evo? If so what do you gave the tire setting at? I have mine set for what the manuel says but my spedo is still about 6-7 mph off

 

Try a value of 2709mm, which accounts for about 3% "squish" (flattening due to weight) on the unloaded circumference of 2790mm.

Remember, your dash speedo will generally read 2-3 mph fast, in the 70 mph range, when you get the correct value dialed in, but your odometer will be correct.

I'll give it a try, thanks

 

Trial and error using a GPS - you want the Edge speed to agree with the GPS.
