CUCV wheels on a K20? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**leddzepp** · 02-04-2022, 01:44 AM

Everyone raves about using 6 lug 15x8 CUCV steelies on K10’s and K5 Blazers to run wider tires. Anybody using 16x8.5 CUCV steelies on an 8 lug K20? They seem to be more plentiful and a whole lot cheaper than their 6 lug cousins.

I've never seen any 16-8.5 cucv wheels before...pics or where to buy.???
Every one of the several hundred that I've bought had the 16x6 wheel

I've seen it done. Not sure what was required, if anything. The are inset, backspace wise, compared to what is normally used. They also have run-flat thingies inside that I believe can be a PIA. I also "think" guys remove those. All hear-say from some time ago with no personal experience. Cool idea for sure. Beasty looking things they are!

EDIT: Oh wait, you said CUCV, not HUMVEE. K30 CUCV wheels are just factory 8-luggers. Eezee peezee. They are the same width as stock, though.

Here are HUMVEE wheels on a CUCV

Guess I'm really out of the loop. I have only seen 16.5 CUCV 8 lug wheels

**leddzepp** · 02-04-2022, 04:13 PM

You’re not out of the loop, the seller is

He just sent me pics and I can tell they are regular 6” wide or so. He claims they are stamped 16x8.5 but I doubt they are

If these wheels were 8.5” wide they would be snatched up and scarce like the 6 luggers.

I have two set of those 16" wheels.

**Joesjunk** · 02-04-2022, 06:02 PM

These wheels are stamped 16 x 6.5. Tell the guy to put his glasses on lol

I bought a set of 5 tires for my 72 burb from a hummer. We unbolted the 2 piece wheels and found 3 of the 37x16.5 tires had run flats in them. Tire shop said to chain them to a tree and to your truck and hope for the best... I thought outside the box and got a porta-power and stretched the run flats inside the tire and was able to work them out. It was not fun.

Glad you cleared this up. I was hoping there was an easy source for 16 x 8.5 wheels.

That tire shop never had any 63 or 91 series maintenance kids working there I see. Get a good CGU-1B and a tire iron and those radial rubber inserts are super fun to change. Been there, done that...

Also people looking at CUCV rims, be advised the Blazers were 6 Bolt and the trucks were 8. CUCV's were being phased out for Active Duty in the early 90's. I got to drive them on the Autobahn and it was fun. When I left that unit most all were replaced by HMMWV's except the contact trucks. Took a while for the Army to get replacements on that model.
