I tried these on two different cars and several tires leaked down over a couple of weeks. My first suspicion was these valve caps which turned out to be correct after I sprayed a mixture of soap and water on the caps. There was a very slow leak around the cap seals.

Sorry, but this product is a terrible idea because it permanently opens your valves. That's just asking for a leak to occur due to leaking seals, sun-cracked valve housing, etc.

The in-tire pressure system may be expensive but at least it doesn't cause a leak in your tires.

I was a little weary of buying these kind of pressure caps, particularly due to the bad experiences which other reviewers have discussed, but I bought a set to try them out anyway. I'm happy with them with over two months of driving with them on. I have checked the pressure with my normal gauge 3-4 times since they've been on, and it's always above 32 psi (as further indicated by the green marker in the cap). Overall, I would recommend trying these out - they really do reassure you that you are driving with the safe amount of air in the tires with just a glance (which is really nice when you obsessively check the pressure).
By the way, I only swapped one cap a week, in order to assess each cap and make sure that they weren't causing leaks (in addition to spraying soapy water on the valve stem and cap to see if air was leaking, before and after installation).

I had the same leakage problem as Micah on two different sets. In both situations only one of the four caps had significant leakage, but in both cases it was bad enough to drop 10 psi in a week.

These caps break very easily and once they're broken they will completely drain your tire(s) because they need to hold the valve open to read the pressure. Totally self-defeating product.

Well, I had high hopes for this product, but they have failed miserably. I read the other reviews and figured I would still take chance on them. I was wrong. I have had them installed for 2 months or so. All this time, they have shown full green. They are the 32 psi models and I run my tires at 34 psi. I decided over the weekend to remove them and check my pressure to see if they were actually working. The first tire I checked with my digital gauge had a pressure of 22.5 psi. And the green was showing full before I removed the valve cap. I took them all off and tossed them in the trash. I will stick to the old fashioned way from now on.

These valve caps (and others like them) will result in leakage that simultaneously create pressure problems while displaying visual false positives.

Tire Pressure caps are a great idea but are not as sensitive as factory Tire Pressure Monitoring Systems and will eventually cause avoidable problems (as described by other reviewers here).

In short Tire Pressure Caps, as currently designed and conceived, are NOT ready for prime time. Save your money and your piece of mind.

The manufacture is not indicated here, but the image displayed looks like the Legacy Mfg. Gas Saver Low Pressure Monitoring Valve Stem Caps I purchased at Wal-Mart. I did not purchase at Amazon, but potential purchasers should be alerted to the danger of these products. I installed these on Easter carefully following the package instructions for the 32 psi tires. I then drove approx. 30 minutes and my vehicle was parked for about an hour. When I returned to my vehicle 2 tires were flat. I had to spend Easter calling the Auto Club and waiting for emergency assistance to re-inflate the 2 tires. If I had not decided to go in the store, I would have been on the freeway with 2 deflating tires. This could have been a very dangerous situation. It is appalling that such a defective product can be sold to an unsuspecting public with the potential of endangering motorists and others. ABSOLUTELY DO NOT BUY THIS PRODUCT!!

I bought these for my 2007 matrix and had them on the car for about 2 months when I noticed one of the clear plastic caps was missing. It appears to have broken off the rest of the part and exposed the colored gauge. For the price it wouldn't buy these again.

These caps are used as replacements for your vehicle's valve caps, and act as individual tire gauges. Simply remove the old caps, inflate your tires to the recommended psi, install the Tire Pressure Valve Caps and you're ready to go.

Of course, you should continue to regularly inspect your tires, but when you don't have the time, it's nice to be able to just glance at the caps and know the status of the pressure in each tire.

When the caps are green, the pressure is ok. When the color is changing from green to red, you know that the tire(s) require your attention. When the color is red, the tire is under-inflated. It's as simple as that.

I believe that the caps come in both 32 and 36 psi, so be aware of this if/when you order. If you normally inflate your tires to 32, it wouldn't be prudent to get the 36 psi caps because the valve would always stay in the red region -- even though the tire is properly inflated. With that in mind, if the recommended pressure for your tires is below 32 psi -- 28, for example -- neither of these products would do you much good.

I think the valves are handy and have been using them for 4-5 months without problem. I did notice that, after inflating the tire and then reinstalling the cap, I did hear the sound of air escaping. However, if you use one hand to hold the tire's stem while tightening the cap with the other, the airflow stops. I tried tightening the cap with one hand, but felt that this method put unnecessary strain on the stem.

We bought tire pressure caps for the whole family. My teenage daughter can now keep an eye on her tires easily without us worrying about her. Love them!
