Driving your car on overinflated or deflated tire is not wise. Unfortunately, not all cars have a tire pressure monitoring system built -in. The FOBO Tire 2 Pressure Monitor can help. It is an iOS/Android connected system that monitors up to 116psi. It gives you heads up on fast & slow leaks and can even monitor your spare tire.
The FOBO Tire 2 comes with Bluetooth 5.0 sensors. It has an in-car unit but you can also use your iPhone or Apple Watch to monitor everything. You can find out more about it here.
