Lug Pattern?

[boggs187]

Is the new 2008 f-250 lug pattern the same as a 2002 f-250? Thanks

[bockhold]

i wouldnt think a lug pattern would change at all

[bockhold]

now what i think would change might be the torque

The lug pattern is the same.... the backspacing is different.... the new one runs either a 5" or 5.5" backspace where as the old one was 4-4.5" backspace.... but most aftermarket wheels will be interchangable...

Just FYI, the older 8-lug Fords are 8x6.5 and the 99+ are 8x170mm. They changed to a metric bolt pattern, but 99-08 should be the same as far as bolt patterns go.

Then there's the 10-lug for the big boys, but I don't remember the specs on those.

coul ya possibly put the 08 rims on the 99-07 trucks. i dont understand backspacing

As mentioned 99-08 SRW SDs have a 8x170mm bolt pattern.

99-04 450/550s had 8x225mm

05-08 F-350 DRW has 8x200mm
05-08 F-450/550 have 10x225mm


99-02 used 14mmx2.0 studs
03+ used 14mmx1.5 studs
(size is the same....thread pitch is different).



You can bolt 05-08 wheels on a 99-04, but they will sit under the truck and most likely the tires will contact the leaf springs while turning unless you use wheel spacers to account for the increased back space on the 05-08 wheels.
With the wheel spacers they will look normal under the truck and you won't have any issues turning.

I almost posted that info Dan but saw that he only has a SRW so I figured it didn't matter.... but I didn't know the thread pitch was different.....

Backspacing is also referred to as offset. It is how much of the width of the tire and rim is behind where the wheel meets the face of the rotor and how much is outside of that. Remember old chrome "reverses"? The tire and rim stuck out from under the rear fenders. They were reverse or negative offset wheels. I think 2005 is when they started putting wheels with some positive offset on the superduties.

[DCSpecial]

Back Spacing and Offset are two different terms and two different ways of measuring a wheel.
But ultimately they tell you the same thing, and with one you can determine the other if you know the width of the wheel.
