Minuet

The attached washers on my lug nuts rattle when I hit bumps in the road. I’m using the stock lug nuts that came with my SC300 on my Lsportline aftermarket rims. I torque the lugs to 76 foot-pounds. The lugs have a cone shaped snout and the wheels have a cone shaped receptor. Should I get washer-less cone shaped lugs? If so where do I get them?

Please advise.

Thanks
