TIRE GUYWant to know about valve covers?


tire valve4 tiny little plastic caps which  cost of less than one dollar provide you with insurance that you can control your car in just about every situation you can normally expect to encounter. 

These tiny little pieces of black plastic (circled in red on the right) which cover your tire's valves are frequently lost and never replaced.  What many people don't realize is the without a cover, the valve is easily contaminated with dirt, sand, mud, water, oil, grease, and many other substances which miight be found on or near a road's surface.

If any contaminant enters the valve mechanism and is present when you add air, or test the air pressure, it could cause the valve to malfunction resulting in an air leak.  If you're lucky it would be a fast leak which you would possibly notice almost immediately, but, more than likely it might produce a very slow leak that will leave you without sufficient air pressure at a critical moment -- possibly when you are far from air or a service shop.

Keep your valves safe, check and replace your valve covers  whenever you notice one missing.  Since they're so small and inexpensive, we'd like to encourage you to keep a couple of spares in your glove compartment at all times.

Novel Solutions
