Hey guys i'm just wondering a few things and I really didn't find the answers i'm looking for so I decided to post up.

I have an 08 screw fx2 that I just replaced the factory 18 inch rims with 265/60? tires for a set of limited 22's with the pirelli tires. I know the speedo will be off slightly and wanted to know if the dealer can reprogram it to spec since it's another factory wheel/tire? (still under warranty so not wanting a programmer/chip)

The truck now pulls slightly to the right and I was wondering if the alignment changed with the different wheels? Does ford spec a different alignment on the limited/harley trucks because of the wheels/tires?

For the pulling I haven't yet rotated the front and rear to make sure it's not the tire/wheel but if it needs an alignment i'll go that route and rotate later if it's still an issue with pulling.

Thanks to people who posted up part numbers for wheel locks with the harley/limited wheels. Amazon prime got them to me quick and cheap!

 

The dealer can recalibrate your speedo for any OEM sizes. The alignment specs should be the same for all of the F-150's as far as I know.

 

try swapping them first...see if the pull follows or changes or goes away.....

 

Since they all have the same spec alignment and i'm guessing the wheels didn't change it much then swapping the rims around is my next task.

Not sure what effect the larger wheel will play in alignment. Assuming it was alignment with the stock 18's vs a general setup that should be the same for every trim model. The more I think about this stuff the more questions I have. Annoying.

 

I have 22 inch harley from a 08 that I installed on a 05 Lariat. I would like you to measure the circumference of both 18 and 22 with the tires installed ,and if they are identical then why would the speedo change.
