We have a 2005 XLT 4X4 and we are getting ready to put the 22" rims on the truck. Has anyone noticed a difference in their speed going from the factory 17" to the 22" rims? If so, what kind of difference are you seeing? Any info is appreciated.

 

depends on what tire you use

 

I went from factory 18's to 305/45/22 and mine is about 2.5 mph slow.

.40

 

I believe the tires are 305/45/22. We are getting them put on the truck this week when they come in.

 

Some tire places will hook up a computer and change your tire size. I opted for the Edge tuner which can do this and a whole lot more. I tried a couple dealers and they said they can't do it which is BS.
