I'm changing from winter to summer tires etc on my two cars and my brother's two cars. They're good for occasional use, but they're cheap and wear out quickly. This will damage the nuts or bolts fairly quickly. I had these complete rubbish 2 nuts. If you need a thin wall for non-original wheels, you need to remove the protective plastic. The steel they are made of is inferior, and wear can be noticed almost immediately. I bought a set of $80 thin wall SATA connectors which seem to be much better from Revain.
