    I found some Ford steel dish 8 bolt rims in 8.75x16.5. I've heard that the center holes aren't quite the same between Ford and GM. I can't remember if the Ford rim will fit ok on the GM axle? Anyone? I'd like to run a 39.5/15-16.5 Swamper TSL on these rims.

    Thanks

    Ford wheels will fit GM. GM has the smallest center-holes on their 8-lug wheels.

    I believe he is correct. The bolt pattern and lug size are the same (although I think Ford used longer studs, so your lug nuts may bottom out if they are not the "open" style or "deep" enough). At the pulls, we have had trouble when trying to swap tires from Chevy to Ford (but a 4" grinder and some time cured that /forums/images/graemlins/blush.gif and NOT recommended), but no problems Ford to Chevy assuming stock rims (aftermarket wheels usually have a center hole large enough to cover Ford, Chevy, and Dodge). I'm not sure about Dodge's center hole as we have not had to swap tires onto one or from one.

    The Dodge is at least as big - or possibly bigger - than the Ford.

    Just remember that anything from a Ford installed on your Chevy could cause the overall value of your vehicle to drop dramatically. /forums/images/graemlins/eek.gif /forums/images/graemlins/rotfl.gif

    Ford, GM or Dodge 8 lug is the same bolt pattern, except the latest superduty Fords which have a unique size, and they don't have much support in the aftermarket yet for that size.

    Ford stock 8-luggers up to the '98 Super Dutys, have the largest center hole. Some of the Dodge's are the same & most, if not all GM's are smaller. I recieved a crash course when trying to find stock 16" wheels for my '78 F-250.
