4Pcs 32-to-35 PSI Car Tire Pressure Monitor Valve Stem Caps

great product

Makes life easier

It turns out that by design, the 32 psi caps won't plainly indicate low (red) pressure until it reaches 24 psi and that's too low for my application. I'm now more concerned about the chance and consequences of one of these leaking so I'm sending them back.

I bought these to put on my classic mustang . I also have them on my daily driver . So far so good since I can’t afford to have the sensors replaced on all my tires

Easy to install and easy to monitor.

As soon as I received this item I should have known better than to put them on the car. All you need to know is that the instructions say that if the car gets wet or goes through the car wash they should be removed. To me this doesn't really seem like a reasonable request but I still gave them a try. Fast forward to only two months later and after checking the pressure of the tires I realized that the color indicators themselves didn't change color despite one of the tires being very low in pressure and even worse is that all four ended up being corroded to the valve stem which required pliers to remove. On top of that one was so corroded that it broke the valve stem itself so now I need to take it into the shop to be fixed. Never again....

I bought these in Dec 2020. They’ve been ok, they just don’t agree with my low tire sensors in my van. I frequently get the low tire light alert on my dashboard (usually when the temperature outside drops dramatically) and all the stems still show green indicators so I’m never sure which tire is low. And if anything hits the end of the cap and you don’t notice it’s broken in any way, you’re going to end up with a 100% flat tire. (Lessons learned from having my teen shovel snow from around the car.) Still rated it three stars because up until the end got damaged they seemed to hold air in fine, the indicator just isn’t as accurate as my low tire sensors are.

Excellent

I was hesitant about using these but they have been great at giving advance notice of tyre pressure going down. Well worth purchasing.

Muy compacto y específico Llegó en buena condicion y en tiempo Funciona perfectamente y se logra ver a buena distancia, perfecto para mí bicicleta y motocicleta 👌

I noticed that my front right tire is under inflated but the indicator is still showing green. Imagine my surprise when I checked the pressure showing 18psi, when all the others are at 36psi. This is a dangerous tool that gives a false sense of security.

Lo instale en las llantas de mi automóvil y ya no me preocupo por saber si traigo poco aire en las llantas ya que esto me lo indica cada vez que paso por una gasolinera.

Excelente
