Valve caps don’t hold in air, they protect the valve stems from weather and debris.

Don't forget to trim your nose hair....

I stand corrected.

No, valve stems can leak air very slowly if they are not tightened down properly. There is a rubber gasket in the stem that needs to be compressed to hold in air. Over time the stems can loosen and require being snugged down, typically only about 1/4/ to 1/2 turn. Sometimes the rubber gasket in very old valve stems can corrode and the valve stem needs to be replaced. A valve stem wrench can be purchased at any auto parts store, or in the automotive department of a box store, for less than $5. A package of replacement valve steams can be purchased on Amazon for under $10.

Correct me if I am wrong but the valve stem is a 1" to 2" piece of rubber and metal that is inserted into the rim from the inside of the tire. It's purpose is to allow the tire to be filled with air through the use of a valve within the stem. There is usually a valve stem cap that screws onto the outer end of the valve stem to keep dirt out of the valve. In newer vehicles the valve stem frequently contains the sensor for the tire pressure monitoring system (TPMS). In all cases that I am aware of, the valve stem is replaced from inside the rim meaning the tire must be at least partially removed from the rim itself. The hollow rubber/metal valve stems can be fairly inexpensive but I know those that contain the TPMS sensor cost more than $10 each.

Perhaps you are referring to the valve itself which is within the stem. Those can be removed and replaced. In all the years I have owned vehicles (cars, trucks, motorcycles, bicycles, lawn tractors, golf carts, wheelbarrows, boat trailers, etc) I have experienced a bad valve only one time. Maybe I've been luck and it happens more often than that. I have never needed a replacement valve (I had the entire stem replaced that one time) but it's good to know they are available.

Ok, my bad, poor semantics. I should have said valve stem CORE (pictured below with tool). Advice still stands, they can come loose and should periodically be checked. They tend to become loose when frequently inflating/deflating and when running tires at low pressure. I had problems with the stem cores loosening on my truck when oversanding on the beaches at Cape Cod several days in a row (the tires are deflated to 11 psi to drive on the beach and then filled back up to 36 psi when getting back on pavement). The cores frequently loosen on my ATV as well. The tires on an ATV run between 3.5 - 5 psi. I’ve never had a problem on cars, but I did need to replace one on a golf cart.

Terminology, ok, no problem. Understand now but still have not experienced that particular problem. Cheap and easy to check so why not?

Me thinks it the jam nut that hold the tire pressure sensor onto rim?

Use nitro not, the bottom line check tire pressure periodically and you won’t have wear or pressure problems. IMO periodically once month. But I’m willing to bet majority don’t do it and majority riding around with improperly tire pressure.

FYI. Costco has this little gizmo for those that don’t own an air compressor. Very convenient, as once you screw it onto the tire stem, it tells you the tire pressure, and you simply put in the desired air pressure and it automatically stops once you get there. Pretty small, and can be kept in a car or golf cart. $50 online or $40 in the store.

Get a Yantu small air compressor from Amazon. They work great. I keep one in each car.

Also handy for bike tires and multiple versions available on Amazon.

Hurricanes change the barometric pressure in the area.

Seriously? BTW, check your spelling in the title.

That's your pull from this thread? So helpful...
