18" wheels to 20"

[06Powerstroke6.0]

Hey everyone,
I was thinking of going to the Ford 20" wheels for my 06 350 lariat. I have the stock 18s now but I really like the 20". Does anyone know if I put the 20" will I have to recalibrate the comp for the speedo? Thanks

if ur tire height is different...yes.
check the tire height of what you have now with the tire height you plan on running, the actual height and the number of revolutions per mile....if they're different, your speedo will be off. How much ur off depends on the amount of change.

Where are you located? I have a stock set of Lariat 20" wheels and tires for sale. I am in Colorado and shipping is $$$$, but if you are close, let me know and I'll get you some pics.
