I purchase similar chrome valve stems for my Audi S4. I thought they looked great and were a nice upgrade from the simple black plastic that all tires have. What a mistake! About 6 months later, well into an Ohio winter, I needed to put air in my tire. I could not remove the metal cap. After time, it rusted and became stuck on my valve stem. I checked the other tires and two others were completely corroded and/or rusted in place. I could not get them off and could not grip the valve stem any harder or risk twisting it off. I tried everything over the next few days, including penetrating oils and heat. I could not get them off. Finally, I had to take the car into my local tire shop and have new valve stems put it. Cost me $100 in labor for 4 stems and 4 simple black plastic caps just so I could put some air in my tires. The Tire shop guys were grinning and said its a rookie mistake they see more than you'd think. Stay with the plastic!

These are a disaster. I live in Vermont, and they will destroy your valve stems in extreme weather. Maybe they work in Arizona, but if you live where there is severe winter weather get ready to have problems with these. I can only second the other one star review. Plastic from now on. My car is presently in the shop getting all four valve stems replaced because of these.
