Need to buy a new trailer wheel for my 6 lug trailer. Are all 6 lug the same bolt pattern? I know there are different 5 lug options. But only see 6x5.5 option for 6 lug.

I just went out and measured mine, just to reconfirm; as that's all I have ever seen.
6 x 5.5

Do you have a picture of the wheel you need? I have a new aluminum 6 lug wheel, still in the box. I ordered a wheel that was sent wrong; and I just stuck it on the shelf a couple years ago; been there ever since. I THINK it looks like this:

I don't need anything that special. It's just going to be a spare I will keep in the truck. I figure having 2 spares is better then 1...

I have these...

You have a couple choices. You can opt for the same steel wheel so if you do ever put it on the trailer, you can leave it there for a matching set.
OR if you want my aluminum wheel, you will have a lighter spare to swing in and out of the truck each time. I'll get a picture of it tonight, as I need to put it in the Swap Shop anyhow.

What ya want for it?

I'm out, and sorry to slow you down.

4 years ago, I peered in the box and realized it was the wrong design wheel they shipped. I was headed out on a trip, and ignored it; stuck it on the shelf figuring I'd keep it for an emergency.

I just pulled it completely out of the box for the first time and realized that etrailer.com shipped me an 8-LUG wheel when I ordered a 6. It even says 6-lug on the box.

Ok no big deal.
