Lug Patterns

[MustangDiesel]

Does anyone know if a 99 SuperDuty F-250 has the 8 on 61/2 or 8 on 170mm lug pattern.

I believe it is the 8 on 170mm. The older trucks use the 8 on 61/2 pattern.

I was hopin they were 61/2 so I could mount a set of aluminum wheels on my gooseneck but if they are 170s I wont be able to.
