4 PCS Car Tire Tyre Pressure Monitor Valve Stem Caps 3 Colors Air Valve Caps Warning Safety Case Cover Sensor Indicator Car Tyre Valve Dust Caps for Cars Motorcycle Bikes

Fantastic very smart item 👌

Only had a month is so and indicates a wrong pressure already, the photo above shows red but tyre pressure is 34 Psi ! They fit well and easy to read which saves checking the pressure especially if you have run flat tyres like I have. But maybe these are just cheap ones hence the price. My other tyre was quite low 22psi but the indicator was still green ! Avoid these cheap rubbish

Presumably it was fine but it was bought as a “stocking filler” for a friend who has trouble knowing if her tyres need pumping up so I have no personal experience of using them.

Good idea but can’t tell if they work correctly

Had get my tyre valves replaced £40Not worth the agro

Didn't expect them to work but they do. One of my tyres tends to go down slowly and they really help me, as soon as it starts to show yellow I pump it up. The tyre looks ok to me but the pressure has dropped.

I've had better ones from Temu. 3 of the set were reasonably OK but the 4th one leaked and caused the tyre to deflate slowly. It's a good job that I have TPMS otherwise I could have either trashed the tyre and/ wheel (total bill would have been £700) or i might have lost grip and had a shunt. When I came to remove them I found that 2 of the 3 had virtually welded themselves onto the valve stems and had to use grips to get them off!AVOID LIKE THE PLAGUE.

Bought these tyre dust caps for their chrome appeal and possible psi inflation use. Value for money, after inflating tyres to correct pressure and screwing on to each tyre valve they immediately turn green indicating correct pressure. This means each time I start the vehicle just a cursory glance at wheel valves showing green reassures me of correct tyre pressure! Magic 🎩 Obviously turning yellow or red represents tyre deflation.
