14mmx1.5 is the correct size. Go with Mcgard spline drive lug nuts as they are the most narrow lug nut available and the supplied socket slides over the outside of the lug nut keeping you from contacting your wheels with a socket or lug wrench and scratching them. They will sit inside the wheel and not be exposed you have a choice of black or chrome with these and they are relatively cheap maybe 25 bucks a set and provide a bit of security for your wheels as they can not be taken off with a conventional socket or lug wrench.
