Not enough information. How new/old is the truck, assuming Ford but what model, number of lugs, is it hub piloted or stud piloted. Older truck will be measured in inches, newer truck will be metric. And if you have a Dayton style demountable mounting (the way you asked the question makes that possible) the spoked wheel has a 20" diameter. Stu

Just regular semi wheel center whole like you would find on any modern semi on the interstate peterbuilt ect
I guess you would say bud type not Dayton's

I am trying to see if the 6 lug wheel pattern on my f600 truck is smaller than a semi center whole to adapt them to 22.5 semi wheels for my pickup conversion

Thanks

The bore varies on those wheels.

You can get a 6 lug on 8 3/4" bolt circle 22.5" wheel from Accuride, part number 28157. Page 19 here, will take some time to load. You can scroll through their catalog to see the various bore sizes, some under 8 3/4". I would be wary and highly skeptical of any redrill, especially any redrill too close to the bore. IMO it would look like dog ^&* too.

These wheels are floating around used as well. Some military trucks as well as Ford and IH walk-in van chassis used them as well.

Depending on your fender sizes, 19.5s might work for you as well.

Your F-600 has a 6 x 8.75" bolt circle. Depending on whether it is stud piloted or hub piloted the wheel center bores will be 6 15/16" or 6 1/4" respectively. Like said the big trucks are not uniformly alike. A common pattern is 10 lug x 11.25" bolt circle. Center bore on a stud piloted wheel is 8 23/32", or on hub piloted is 8 21/32". There is also a 10 lug x 8.75" bolt circle that has a 6.5" center bore. I'll save you the metric examples. I too think you're barking up the wrong tree. Stu

Thanks for the info guys

I don't think I explained it right I am going to machine wheel adaptor plates so the six lug will bolt on to the plate then there will be the 10 lugs on the outside to mount the 22.5 semi wheel

What I wanted to make sure of that my six pattern would through the center that way my adapters wouldn't put the wheels out to far and I can hide the six bolt pattern behind the center cap

At least this is my plan but open for ideas

Again thanks
