Two of them leak air slowly, sometimes. I'm pretty sure it has to do with having a ton of mud/grit in the valve stems/beads.
They all have about the same tread depth left. Maybe a litttle less tread, but they're all pretty close. They're still on the truck so I couldn't take a picture of them all together.
I'm pretty sure they fit a chevy 6 lug. It should be a 6 on 5.5 pattern.
As for trades, I could use a set of 8 on 6.5 wheels and tires for my new axles but that's about it.
