Plain old steelies
 

I've read several threads about stock steelies. I picked up a pair off of craigs list and I'm trying to identify. They are 15x6 (I think - hard to measure with tire on). Center bore is 3.5", lugs 6 on 5.5". But there are no manufacturer marks anywhere on them (K-H or other). Are these just some aftermarket trailer rims? Or could they be OEM. Any help is appreciated.

those appear to be pre-1970 OEM C/K10 wheels. Key ID feature is 3 cap retention nubs (vice 4) - these will not likely fit over disk brake calipers for awareness.

I think you are right about them being trailer wheels. The factory wheels don't have those raised areas between the lug nut holes. The earlier factory wheels with three hub cap nubs don't fit over disc brake calipers, but these non-GM wheels might. One company making wide steelies uses three nub centers that work with disc brakes. I believe the ceneters they use are for trailers

Here is a GM disc brake 6-lug wheel

Post up a picture of the back side of the wheel, please.

The front looks very similar to the stock, drum brake wheels I pulled off my 63 when I went to discs

Re: Plain old steelies
 

I have 2 sets of wheels and a spare that look just like what CJ847 posted with the raised parts around the lug nuts.

Both sets came from 1968 model trucks. One of which was very original, so I can't imagine they were changed out.

I have a set of 6 lug disc brake wheels(and a spare) like Special-K posted that do not have the raised areas.

I think you have original 3 nub wheels.

Here are a couple pics of the original wheels from 1970 C10. They have three nubs and the raised areas between the lug holes. These wheels will not fit over disc brakes.

Chris, your post rung a bell for me, I meant to state '70 and earlier' (vice pre-70) in post #2. Thank you!

I learned something new. Excellent.

Remove the tire and you will find the manufacturer stampings which are required for all wheels.

Re: Plain old steelies
 

Haven't had a chance to remove a tire. Will report back if/when I do.

While we are documenting, I was curious how some 15" will work with disc brakes and other won't. A quick look at the back shows the difference. Hope it shows up in pics.

15" DB wheel (1982 c10) the one with 5 lugs.

15" non DB (assumed to be 1970 or earlier)

As you can see the db maintains approx 13.5" dia all the way to the center. The non disc dia is reduced within an inch of the bead.

Re: Plain old steelies
 

Yup, the wheels you picked up are the typical, stock drum brake wheels found on most early c10s. You can make them fit over disc brakes by running a spacer, but if you're staying with drums, you're all good to run those

Re: Plain old steelies
 

Yep, once you get the tires off it's easy to see the different shapes of the wheel barrels.

First pic is a drums only wheel. Second pic is a disc brake compatible wheel.
