Review on Valve-Loc Tire Valve Caps (10-Pack): Universal Stem Covers for Cars, SUVs, Bikes, Trucks, Motorcycles - Heavy-Duty, Airtight Seal, Hexagon Design by Adam Krueger

The tire pressure sensor on the dash came on and as you might expect I decided to check my tires for pressure and to fill air through as needed. Only thing that didn't come off were the nice shiny valve caps I bought. I couldn't take them off with my fingers. I couldn't get them off with pliers. I could not remove them after spraying penetrating oil and anti-rust solvent on the threads and using two pair of pliers on the valve cover and valve stem. and sensor and reinstall them. I figured if I paid $260 I'd at least try it first, so I broke the dremel up, put a cutting wheel on it, and cut one off. A few nicks on the valve stem threads, but it came off. Do you see the white dirt on the valve stem threads and on the cap threads? This is corrosion that has blocked the valve caps on the valve threads. They didn't come out any other way than by cutting them off. DO NOT buy this junk.
