odometer recalibrating

[bmiller2000]

Anybody know how to do this or have options for bigger tire upgrades? Would like to know what my true mpg and speed is.

You can go to the dealership and have them do it. They can only go up to about a 36" ire though. There is a box that you can buy too. I don't remember right off what the name of it is though.

best way is Super LIft tire recalibration

its called Truspeed by Superlift, works great if you have ginormous tires, cost about $180

yeah true speed is the way to go i got one and its great

[bmiller2000]

there are just 285's I'll just keep wondering instead of $180

[Strokethis9]

i really dont think you need to worry about it if they are 285. you are maybe goin 1 or 2 mph faster than you think you are goin

The dealership here quoted me 60 bucks to do mine

if the tires arent that big but still bigger than stock then just have ford do it, should be around $50-$70, I believe they can program for up to 36" tires. But yea you're probably not even going 5mph over what the speedo says.
