I ended up buying these for 720. Tires for were 9/32nds and rims pretty good. Gave too much trust to this guy, and just went through it quickly. Took it home to find out that there was a hairline crack on the inside of the rim.
Took the pictures and immediately texted him. He said he was unaware of it and I asked him if we can go 50/50 split to repair/re-weld the rim (my fault for not looking thoroughly). He said he'll think about it over the weekend. Message him this week a few times, no more response.
Grow the fck up, you're not a kid anymore. Take some responsibility, I wouldn't think that I would be scammed on the forums. I was willing to go 50/50 with him. Moral of the story, carefully check your purchases, trust no one.
