Do I need new lug nuts for my aftermarket 20 inch wheel or can I use the stick lug nuts? Thanks

I think, what you actually have to check how the holes are shaped on your new rim. Conical bolt heads must not be used in spherical holes and vice versa. If the bolt heads fit you can use the old ones.

This is a critical matter - using the wrong nuts could ruin the wheels at best, cause loss of a wheel at worst. If you are not absolutely clear on the difference in ball and cone nuts, you need to check with a good tire/wheel shop.
