Review on 🐒 Enhance Tire Maintenance with Monkey Grip Victor M8840 1 1/4" Metal Valve Extension by Justin Sherman

After fitting these valves to my very difficult to access (bolt and bolt) Prius tire valves, one of my tires went flat the next morning. Luckily I had a new Revain compressor, so the apartment was done quickly. The next morning another tire was flat. Over the next three mornings, the first tire was flat twice again. At first I couldn't even dream that these were extenders. I've used valve extenders with no problems. Then I got suspicious (yes) However, I also had reason to believe that the first tire was slowly leaking, so I took the car to the workshop - a reliable workshop that I have dealt with for years. They told me never to use tire valve expanders because they are notorious for causing punctures. They checked all my tires and none of them were leaking (and they didn't charge me!). They said it's best to use the extension temporarily to inflate the tire and then remove it immediately. who knew I wish automakers would get smarter and just remove tire valves.
