Features: 1. Dynamically monitor the tire pressure of 4 wheels at the same time to prevent tire blowouts, improve fuel efficiency, extend tire life and ensure driving safety. 2. It is designed as a direct tire pressure monitoring system by installing pressure and temperature sensors on the tires and displaying the real-time data on the mobile phone (for Android for IOS) via Bluetooth connection . 3. While driving, tire pressure and temperature are displayed in real time, and an alarm is issued when the statistics are abnormal. Support for Android and iOS, Bluetooth 5.0 or above is required. 4. The 4 sensors adopt waterproof, anti-corrosion and anti-theft technologies, perfectly suitable for rainy weather and suitable for outdoor use. 5. Using top chip, high sensitivity and high stability, high pressure and temperature measurement accuracy. Battery life is 3-5 years and is easy to replace. 6. It can help you save up to 11 cents on fuel per gallon when inflated properly. And you can maintain the car tires yourself, without having to go to the car dealership.

Install the sensors on the corresponding tires according to the sensor markings until the installation on each sensor is completed. Note: If the sensor data cannot be obtained, please reinstall the sensor (install it slowly so that the air pressure is in full contact with the sensor) How to use: 1. Remove the valve cover from the tire and install the anti-theft screw; 2. Install the external sensor on the tire valve in order; 3. Hold the sensor and tighten the anti-theft screw. (Each sensor has a unique identification code. Please make sure the sensor is installed on the corresponding tire valve). Package List: 4 x Tire Pressure Sensors 4 x Screws 1 x Wrench 1 x Manual Note: 1. Supports mobile phones with Bluetooth 5.0 or above. DO NOT support cellphones with Bluetooth below 5.0. 2. Presentation of products by mobile phone. While driving, be careful when checking tire pressure and temperature on your cell phone. If the tire pressure accelerates or increases continuously, please stop the car and check if there is a problem with the tire.3. This product can read tire pressure and temperature, but it cannot avoid a sudden accident caused by the tire. It is important to use high quality tires. A slight tire leak causes tire pressure to decrease over time, this is normal. It has nothing to do with the installation of this product.4. Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering.< /div>
