I picked up a nice set of 18" rims for a great price cuz I was kinda getting tired of the ones I have on there. They came off of a Nissan Maxima. The bolt pattern is the same and but two of them have sort of an "inward tapered lip" where it slides over the hub, and they will not go on. The other two will bolt up ok, the have a normal taper and the wheels slide right on. They are TSW wheels, and that company sells alot of staggered wheel sets, is that what these are? Do I need spacers for the ones that wont go on? Based on the stamping on the inside of the rim, I cant seem to find the style on the TSW website to try and get more info. Any ideas?
