You are buying all nine Hubcaps pictured. The 4 on the top row fit the 14" 5 lug alloy wheels seen in pics #2 and #3 which was used on some early to mid 1980s BMW 524, 528e,533i and 535i models. The back measures 2 3/4" clips to clip and the front face measures a little over 3". The four on the next row are smaller and those were 5013 inch alloy wheels but I'm not sure what year model and the one on the bottom your guess is as good as mine. Any questions just ask. Your purchase is a legally binding contract so please read the entire description before purchasing. I will be happy to answer any questions you have but I will not accept any cancellations under any conditions.
