Review on Enhanced Tire Balancing with TyreBeads - Filtered Valve Core - 4 Pack by Eric Glup

rubbish. I should have listened to the reviews I read before I bought it. After a week or so they lose air until one day you realize your tires are flat. Don't buy them. Just use regular valves and be careful when deflating your tires to make sure the beads don't get stuck in them. Those spring loaded ones are junk
