75 delta88 royale- wheel sizes

shaunr · February 9th, 2007, 09:09 AM

I need to know what size wheels I need for my car. I previously postes a thread about my situation with some 20" rims. They don't fit, but I need to know what the bolt pattern is and what the centerhole diameter is also. I want to put some 20" or 22" rims on it. But I want to buy the right ones. People at the stores act like they don't know anything about my car. I know someone here can help me. Thanks in advance.

You probably need a 5x5 bolt pattern

I believe my 1977 Delta 88 has a 5 bolt on 4 3/4 inch pattern, but I know the earlier years had the 5 on 5 pattern. I'm not sure what year that changed. There should be a raised circle in the center of your axle, inside the wheel studs. For the standard hub cap style steel wheels and early bolt on centercaps the center fits over that, so you could measure that. For the later snap on center wheels I don't think they have anything that fits tight against that axle center but just use the wheel studs to align the wheel.
