I'm looking to finally upgrade and get bigger wheels and was doing some browsing a few minutes ago. I saw some 20" wheels with bore 5 x 139.7 but the website said they wouldn't fit my truck. Can someone remind me if that is so. I have a 1997 F150 Lariat (4wd).

 

They will not fit. Your pattern is 5x135.

 

Thank you. What about 6 x 135?

 

No you have 5 lugs, not 6.

 

Right.
