I bought some used 17" OEM vibe wheels but the seller could not find the lugnuts so I need to purchase some lugnuts and wheel locks. But first I need to know what type of Lug nut that this wheel takes. The seating surface on the wheel is flat so I do not think the wheel uses radius or cone seat. I think it is a mag or shank style seat. But I want to make sure before I go out and buy anything. Could someone please post a picture of an original equipment lug nut used on the OEM 17" wheel? The dealership did not have any in stock or a picture of what they look like and when I took it to Belle Tire - the guy said it looked like a mag or shank style seat but he referred me to the dealership just to be sure. Please help. I am also going to post this over at Matrixowners.com as well.Ed
