don't take my word for it but they "should" be 73mm wheel bore and you need a 54.1 for the inner diam. , just go to discount tire they have em... just ask em to let you try it on first they are like 5 bucks... they sell the plastic ones made by gorilla... kinda cheap but they do the job... some people like the aluminum or polycarbonate ones... but to me i think they all work just fine

centerbore size can vary depending on the manufacturer, although many companies use a 73.1 centerbore, howver some are different. it should be marked on the wheel box, but usually is not stamped on the wheel itself, what brand of wheel are they?
