Review on Xotic Tech Tire Stem Valve Caps Wheel Valve Covers Car Dustproof Tires Cap Leak-Proof Air Protection Screw-On Easy-Grip Use For All Cars SUVs Bike Motorcycles Trucks (Gun Grey Grenade Bomb) - 4PCS by Erik Wesley

I really like their design and I think they are the coolest things in the world and they don't change color like my red ones. The first 6 months with them everything was fine. Here it is a year later and the dealer absolutely CANNOT remove them without breaking my valve stems. So there is no way to add or bleed air. So I'm at the tire shop now, taking them off and possibly swapping out the valve stems and/or sensors. Repair over $100. Do not spend money on it because in a year you will be spending a lot more. So upset that this happened. Don't let yourself be in this position! Avoid these things. Just because they're cute doesn't mean they should be carried in the car!
