Review on 🚗 Smart Car Tire Pressure Monitoring System - 6 Alarm Modes for Universal Vehicles - Wireless Solar & USB Charge - 4 External Cap Sensors Included - Real-Time Pressure & Temperature Alerts by Darin Marshall

I bought this to check the air pressure in my RV. It never read the right pressure (30psi deviation), but it did register something, so I figured if I had a runaway, I'd know something was up. Today I had a bearing failure on the way home and this system never warned me that I had lost a tyre. I had one person flash their headlights to tell me I had a missing tire. I have an F250 and my trailer isn't that big so I never felt it on our bumpy roads. After I was about 8 miles from him he said my air pressure had dropped. I would not recommend this item. I would return it but I only have 3 sensors because one of them was lost along with my tire in a swamp on Highway 90 in Louisiana.
