2. Check and be certain the approved lug nuts are correct for the application.

LUG NUTS: It is critical that the lug nut matches the thread diameter, pitch and seat, otherwise the installation will be improper, and may result in damage to your wheels and could cause a dangerous condition. The three basic types of lug nuts are: conical seat (60 degrees taper "acorn" and "bulge"), mag or shank style, and spherical or ball seat. Thread diameter refers to the diameter of the stud measured across the shank at the outer edges of the threads. Thread-pitch means either the number of threads per inch or if metric, the distance in millimeters between threads. The Seat means the area on the wheel where the lug nut will clamp down.

It looks like buldge is a type of conical.
