I am going to level my truck and get some larger tires put on it. What does everyone do about the speedometer difference? I am new to this concept, but understand Forscan can adjust the difference?

Does it change the rate miles are put on the truck odometer?

I am sure this has been answered a bunch of times on here, but I would appreciated knowledgeable answers, not the "why don't you try to search feature" guys.

Thanks

 

No experience with Forscan but from what I've read I believe the answer is yes, it can make the adjustment. I went from stock to 33's, don't know how far off my speedo is but I doubt it's more than 5 mph at 70. Just been riding it the way it is.

Larger diameter than stock tires would have the truck covering slightly more ground every revolution of the wheel than what is registered on the odometer, but I'm willing to bet the difference is fairly negligible.
