I have a 1966 beetle with 5 lug hole 15 inch steel wheels. My question is this; how do I determine what size hub caps it uses? The reason I ask is have found hub caps from various places all claiming that they'll fit the wheel, but the measurements they have given me ranges from 9 inches to 10 inches. So I take my trusty tape measure out to the car, and try to figure out the size, that's when i get lost. I havent a clue from what point to what point i should measure because there are 3 "tabs" around the wheel that if one was to draw a line from one to another would form a triangle. Obviously the hub cap fits between them, however I can't figure out how to get an accurate measurement. Need some help here. Please keep it simple because if it goes much beyond basic math I get start getting lost.
Thank You, patrick
