I just bought some wheels and tires of someone on facebook marketplace. He said they are gm wheels but doesnt know from what truck they originally came from. The back has no part number just says "136c 0 18x9j and made in italy." If someone can help because im trying to find the center caps for them.

 

Doesn't look factory to me.

 

I thought these were common. I swear they are called 6 shooter, or revolver wheels. I don't think they are chevy though. Same bolt pattern, but id be looking at canyon/colorado, titan, FJ cruiser. What else is there? Just looks like an import design to me.

Are those tires Pirelli zero 285/60/r18. Doesn't sound like a stock size to me, but maybe try searching for those, and you might get lucky.

Whats the ET/offset? That will help narrow it down. A big offset should be an import wheel.

 

The et is 0 unless he missed it somewhere, I wanna say I've seen them on forza but I haven't played that game in a while and my Xbox doesn't work anymore.
