Review on BWONE Waterproof Dustproof Corrosion Motorcycles Tires & Wheels by Cody Stroop

The caps are welded onto my valve stems and cannot be removed without breaking the valve stems. I had 2 flat tires in 2 weeks while waiting to get to the shop just because my tires needed air. Terrible purchase. I've been told it could be the material they're made of and the metal they're made of, a bad combination, but I'm not even sure what they're made of.
