Congrats on the Tradewinds purchase and hope you really enjoy it. As far as the lug nut covers I'm not sure about your particular one's but ours had a special wrench that was destroyed when I had new tires installed. I just purchased a socket of the size needed and use it as a replacement for the wrench.
