Monitor Tire Caps (4pcs)

I tend to not check my psi a lot and this really keep it in check for me. It does the job for me so i don't see why i wouldn't give it a 5 stars.

What an innovative idea. These valve stem caps lets you know when you are low on air. They turn red, so it's visual. Great idea, if you have an oder model car that does not let you know through your dashboard that you need air. I gave them to my son for his truck and immediately after putting them on, you can tell he needed air in a couple of tires.

These stem caps work great for providing a quick glace and knowing that your tires aren't low on pressure. I use them on my motorcycle where tires are essential to life and death. I also check pressure before going for a ride and these make it easy to see whether I'm in the safe zone or not. These saved me once already when I came out to my bike and saw the low-pressure indicator. I checked the tire and found a nail through the tread. If I hadn't checked this, I may have had a significant accident due to tire failure.

I bought these for my trailer as no one ever seems to check the air in the tires on it. These were very easy to install as they just screw on just like a regular cap. I really like how the different colors show you whether you need air or not. I would highly recommend these especially if you have a teenager starting to drive or a vehicle you may not use often.

My car has more sensors than it knows what to do with, including tire pressure. I'm usually dealing with a new tire sensor alarming every few weeks and when checking the pressure all is well again. I think it may be related to weather fluctuations so decided to try these as a solution. Really happy I did as the readings are accurate and it's very easy to see if there is an actual issue or not. Quick install, and peace of mind restored.
