We have two 1989 F-450 & 1992 Super Duty with the 16" Wheels 10 lugs.

Can we get 19.5" wheels with that bolt pattern? What year did these trucks change over to the metric bolt pattern?

Have been looking it seems like they are available on the newer style 450 & 550. Would a larger 22.5" wheel also available?

Just wanted to check out the options before purchasing 6 new tires.
With the larger tires & wheel we would improve the fuel economy ect..

We appreciate your feedback.

Ty,
