Am I getting this right? F-250/350SRW, 99-up, 8x170mm, 125.10mm bore. F-350DRW, 99-04, 8x170mm, 125.1mm bore/ 05-up, 8x200mm, 5.6" bore? F-450/550, 99-07, 8x225mm, 170.1mm bore/ 08-up, 10x225mm, 170.1 bore F-450 pickup, 08-10, 10x225, 170.1mm bore/ 11-12, 8x200, 5.6" bore? I read that the new 2011-12 F-450 pickups have the same diffs now as the 350s, so I'm assuming they have the same bolt pattern as well? And do the Cab and Chassis models retain the same larger diffs with the 10x225mm pattern? Any info or corrections would be appreciated.
1) i dont think the bolt pattern changed in 05, but the backspacing/offset did
2) i was under the impression that all chassis cab models had 10 lug wheels, but this may not be true.
3) the f450 pickup had 10 lug wheels for a few years, but then was downgraded to 8 lug wheels, and a 170mm bolt pattern.
to summarize, i dont know where you get the 8x200 bolt pattern, but i dont think that it was ever used on a superduty pickup
Ya, my old 2000 F-550 has an 8x225mm pattern. I just read that the 2011-12 450 pickups have the F350 diffs in an effort to save weight. The 8x200 pattern I got from Rickson wheels and think they are a good source, but I have yet to confirm if this is correct. sorry for the way those #s came out, I had them charted and thats the way it came out when I posted it. The concern is, im looking for a new 450 work truck and want to transfer my AF 22.5 wheels over to the new truck. but want to make sure they will bolt on. The other patterns are just for personal reference as I have had conversations with a few different people about Super Duty bolt patterns and want to have it sorted once and for all.
