Centerline Aluminum wheels. I believe they are 15x10. I've never had the tires off (more on that later) the check the width. They are 6 lug. I don't know the back spacing, but I can measure if you like. Not very shiney, but I don't think they ever were. Had them on my K5, didn't have any clearance issues. They are being sold with the tires on them. 2 are good, one is pretty bald and the other is really bald/has a big hole in it (why I stopped using them). I tried taking the bad tire off...it's on there realy good. I assume it's been on there for a while. I've owned them for 4 years and have never had them off. I can only guess if the other 3 are the same way. They come with center caps (two open/two closed) and maybe the chrome lug nuts...if I can find them all. I'd like $200 for all four, but I'm a little flexible on this. I'd prefer not to ship the tires/wheels, but if you like, I'll try getting the tires off so the wheels could be shipped. I can get more pics too.
