I have an 05 regular cab STX, with the 17" x 7.5, I believe the offset is +44mm but I'm not sure. Will 20x10" wheels with an offset of +44mm fit the truck. Any info would be of great help as I really don't know much 'bout offset or backspacing. Here's the link of the wheels I'm looking at

That has 7.125" of backspacing. I think that will give you trouble. Stock is 5.5". You want as close to that as possible. I am sure Wandell will be around to confirm or deny that.

 

It says on the site that they fit 4x4's only. I'm not sure what the difference is with 4x2's.

 

I found a ford racing parts catalog and it lists this wheel as having a 6.295" backspacing and being 20x9" and not 20x10". will these fit??

 

Yes.

 

Thanks Wandell, you're the man...
