Rim size

[bassbelly]

i have 08 f350 can i run 16.5 rims on it. found military tires for cheap and want them.

As far as I know they should physically fit but it may be hard to find 16.5's that fit your bolt pattern without re-centering the wheel.

[bassbelly]

didnt even think about that. thanks for the reply

X2 on finding a wheel in your bolt pattern. I don't think they will fit anyhow, I'm a Ford tech and the 17" wheels that come on the 08' trucks seen to be real close to the caliper. I work night so I'll look tonight to see how close they are.

If the rims are military as well, they will be 8 x 6.5. Your truck is 8x170mm

Won't fit

I've seen some 8x170mm wheels that are 16.5 x 10 or 12 on ebay and craigslist, mostly welds, I would test fit one before buying however. I know the backspaceing changed between the earlier and later superdutys, this may help, then again it may not. Keep in mind if you do go to a 16.5 wheel there are fewer and fewer tires available for them, it would suck to buy wheels to fit a cheap tire and then not like the tire and be stuck with very few options for other tires.

i have seen a 08 with 17s and 38s - i couldnt fit my fingers between the caliper and the wheel - a steel wheel may fit, but and aluminum may not

As far as I know there is no 16.5 that has enough backspace to clear the callipers. As far as all of the swaps I've done only one American Racing Wheel, Walker Evens, and Robby Gordon 17s even clear with an extreme offset. Your outher issue is that Ford created a serious problem with the 08s by changing the offset center point again and adding rato to the steering box. Now we are starting to see death wable with as small as 35s with dual stabalizers. And we blown up three gear boxes between 2 trucks, twice on the one with 37s and one on the one with 40s. Be carefull.
