Quick Pressure Tire Pressure Monitoring Valve Caps Sensor Gauge - Advanced Detection System, 26 PSI Sensing Air Alert Indicator for Cars, Trailers, Bikes - Chrome-Plated, Pack of 4

Excellent product which makes it easy to see the correct tire pressure.

I got these on my 25 Cougar. No issues or complaints. You can really see the green indicator from an appreciable distance and they do not leak. I’ve got 2 months on my installation and haven’t lost the slightest pressure. They seem very durable and well made. Look nice too. A bit pricey but with a caveat, it’s a better price as compared to a TPMS.

I now can check my tire pressure with a look awesome and easy to know if I have to drag out the air compressor. simple install will save me from buying tires due to low pressure issues.. great product that fit right. quailty and value all in one.

As advertised..

Work great

First install, 4 out of 4 leak. All installed by hand on travel trailer. I would not recommend. I have used many by a different manufacturer, but that part is currently not available in PSI I need, so I tried this manufacturer. They all leak around the plastic clear part that shows the red or green for pressure level. See pictures for what to look for. I applied dawn soap in water mixture spray bottle that I test propane lines with, then left them for about 30 minutes. Only 3 pics because I wiped off bubbles on 4th tire cap before I took a picture of that one. I am glad I tested these, as the tires would be flat if I hadn't. The leak can not be heard, and as you can see by the tiny bubbles the leak is very slow. I am guessing the tires would be dangerous to drive low in a day, and probably flat in 2 to 5 days.

Great quality. Have had over a year now and very satisfied. I would buy again. With that said they are pricey. But these are a real step up from the China junk out there.

I have been using these pressure monitors on my car for over 3 months now, and I am amazed at how well they work! As these are rated for 40 psi, I keep the tires inflated to 43 psi and now I can check pressure on each tire simply by looking for a green indicator. Excellent. Few things I noted... After hand tightening a monitor to the valve stem of each tire, you really must drive your vehicle for like 10 miles first in order to "prime" them before you'll get an accurate reading. So, keep this in mind should you ever need to remove the monitors for any reason, like when it's time to change your tires. After a monitor has been showing all green for a while, if ever it begins to show just a little red, then that is an indication to check the tire's pressure immediately using a good quality pressure gauge. To save the most gas (in this case by reducing friction with the road) you'll want to inflate most tires as close as possible to "max press" (maximum pressure) rating stamped on the sidewall. I had a buddy in college who was a real cheapo and always kept his tires inflated to max press with nothing bad happening. But that still makes me nervous, so I try to stay 5 psi under the maximum rated pressure. Chris
