If, like me, you change your wheels and tires a few times a year, you need quality, durable nuts. Yes, aluminum nuts are good - they're lightweight and they don't rust. However, after putting them on and taking them off several times, they tend to tear or the threads begin to fray. A quality set of Gorilla Steel Nuts is a great option. Threads will be strong and durable. They look good and the knurled ends prevent the strands from twisting when you start to work. Be careful with rim cleaners as they can stain the paintwork.
