Review on Senzeal 5X Long Spike Valve Caps: Aluminum Car Tire Valve Stem Caps with Colorful Bike Tire Caps by Dan Sturm

At first it looked pretty cool on my car and I liked it until one of these fell out easily the same day so I replaced it. Then I went to the car wash, the spike actually caught on something there and bent the tire causing the air to leak out and eventually deflate. I took my car to the nearest dealership and said I couldn't replace the stem so I had to buy all new tires. So. Don't take anything that protrudes far beyond the rim of your tire until it snags, in my opinion. Definitely not recommended. Just stick to the cap.
