i'm about to put 35's on my OEM 18" wheels on my 2004 FX4 supercrew. i was just wondering if my odometer will be off with me changing the size of my tire. if so, can it be corrected and do most people correct it or leave it alone??

 

Yes, it will be off. You can correct it with just about any of the aftermarket computer tuners. The dealer may also be able to correct it.

 

your speedo will be off a good deal as well with out that recal

 

A good excuse to get an Edge or an Xcal2. I think the dealer charges about $100 for recalibration. That would be a downpayment on a tuner!

 

im a proud owner of a edge unfortationaly for my year dont recal tire sizes but you wont have that prob though and u will really love the results
