Anyone know if the offset is correct on a 2009 f150 Platinum wheel to fit the Expedition. The car I'm getting has 18s and I plan on installing a set of chrome 20" ford wheels with one size taller michelins, 275x60x20 vs the stock size 275x55x20 The 60's are virtually the same width and section, but almost an inch taller and should ride a bit better with the extra sidewall as well as filling up the wheel well a bit

Anyone know what the expedition 20" offset is? I believe it's stamped on the back of the wheel. I believe all the expedition and f150 20x 8.5" wide wheels have a 44mm offset but not certain

 

Yes the wheels will fit fine ( same offset F150 = Expedition 2004 up)

You will have to have the computer reflashed to adjust for the difference in tire height though.

I really ha e to ref lash for a .9" change in tire diameter? Can the dealer do that?

 

Check out this link. It will show the variations in tire sizes in relation to actual speed.

According to the calculations your speedo would be of 2-3 miles per hour. I think the problem is the computer is expecting to see x # of revolutions per mile when it does its calculations for Advance Trac/ RSC and yaw control etc......

I would think a dealership could reflash it.
