I have a set of aluminum 16.5 x 10 wheels with 33x12.50 mudders on them. I am looking for a set of factory 17" FX4 wheels for my 98 F150 4x4. I do not like the old tear drop style 4x4 wheels but I love the FX4 wheels. I do alot of hunting out of my truck and the wheels I currently have now just sling too much mud and are too ruff on my truck for hunting. If anyone knows where I may be able to find any factory wheels please help.

 

I know the factory wheels were 16" or 17", not 16.5", so you would have to replace tires too. I would try ebay to see if you can find wheels. They will be 16" or 17" x 7" wide with a 5x135 pattern. Your vehicle has 12mm lugs. You may want to look for 97 - 99 wheels as they were made for that size lug. After that the lugs were 14mm so the lug holes are bigger. My understanding is that the later wheels will work as the wheels are hubcentric, but that is not for sure as I have never tried it.
As far as 7" wide wheels, I don't know if that is wide enough for the width of tire you currently have.
Good luck on your search

 

I may add some FX4 wheels to my 99 Expedition. I am thinking 12mm Lightning lugnuts may work. I am waiting for pictures of both lug nuts.
