Review on 🔒 Set of 20 Chrome Plated Brass Tire Valve Stem Caps with N2 Nitrogen Sign Logo - Dustproof Valve Covers for Car Auto Tires by Andrew Mclemore

They allow you to keep the valve stem caps visible to the footman who wants to AIR your tires that you have nitrogen. If he/she knows what N2. Wears a hoop with a slight touch of class. Good for carving where they don't come loose every 100 miles. I've built two trucks (4 each) and my scooter and I have eight left for another car or for a friend using N2. Worth the extra dollars and if one gets stolen you have a spare.
