Flat Rims Used on Coined Hubs?

Hi All,

I picked up a set of 16" dually rims for my 1977 Ford Brougham RV to replace the 16.5 wheels. I didn't notice it but the 16" rims that I bought used are "flat" and the 16.5s on the RV are "coined." The hub diameter and the lugs line up just fine. Will the flat rims work on the coined hubs? I hope so because it was hard enough to find these at a decent price.

Any help greatly appreciated!

They might work if the hub diameters are a mate.
If they are not, you are lost.
This is because your wheels were "lug centered" and all flat wheels are "hub centered".
The other problem is that you will have to get the correct lug nuts and tighten the bejesus out of them.

People have "coned" 4 of the 8 flat lug holes with a taper reamer of the right angle to allow for the 4 coned holes to use tapered lug nuts to center the wheel and 4 of the flat style to be used for the remaining 4.It requires 2 different sized lug wrenches,but gets the job done safely.
