Product Overview This tire pressure monitoring valve cap is a practical automotive safety accessory designed to help drivers easily monitor tire pressure status. It features a 3-color eye alert system that provides real-time pressure feedback, supporting safer driving and extending tire life. Suitable for most standard valve stems, it fits cars, motorcycles, and bicycles, making it a versatile safety solution for various vehicles.

Core Advantages
3-Color Visual Alert System: Green for normal pressure, yellow for a 10% pressure drop, and red for a 25% pressure drop, allowing instant identification of tire pressure anomalies without tools.
Enhanced Driving Safety: Effectively prevents tire wear, blowouts, and poor handling caused by under-inflation, maintaining optimal tire pressure for safer driving and better vehicle control.
Wide Compatibility: Calibrated for 36 PSI (2.4 Bar), it fits most cars, motorcycles, and bicycles with standard valve stems, offering broad usability.
Durable & Reliable: Constructed from chrome-plated metal and PC material, it is wear-resistant and built to withstand daily use, ensuring long-term stable performance.
Easy to Use & Maintain: Simple installation and operation, with clear visual feedback; easy to remove during car washes or maintenance to preserve accuracy.

How to Use
Installation: Remove the original valve cap, screw the monitoring cap clockwise onto the tire valve until tight, ensuring a secure fit. Pressure Reading: Check the color of the eye indicator:
Green: Tire pressure is normal.
Yellow: Pressure has dropped by about 10%, recommended to inflate to the standard value.
Red: Pressure has dropped by about 25%, inflate immediately to avoid safety risks.
Maintenance Note: Remove the cap before entering an automatic car wash or during garage service, and keep the black washer properly stored to maintain measurement accuracy.
