• Energy Efficient. Integrated lightweight plastic and aluminum seamless structure design, to achieve the industry's lowest energy consumption at the same time, to ensure that all four wheels independent and accurate tire pressure monitoring and timely response.
• Extend Tire Life. Relying on the new generation of NTM88 chip technology, it can monitor the tire pressure in real time, know the tire status, and provide sensitive feedback and timely response for safe driving, which is not possible with other chips.
• Powerful Battery Life. The Maxel or Panasonic CR2050 battery used in the A-Premium's Tire Pressure Monitoring System Sensor can last at least 5 years with its high and low temperature resistance and low energy consumption, and outperforms other similar products in terms of battery life.
• Multiple Test Endorsements. A-Premium is salt spray and pressure tested to meet the stringent SAE J2657 standards, minimizing the frequency of follow-up maintenance in its class.
• Compatible with a Wide Range of Usage Scenarios. A-Premium's Tire Pressure Monitoring System Sensor is not only compatible with temperatures ranging from -40 degrees to 120 degrees, but also has excellent sealing properties, making it the strongest waterproof and dustproof product of its kind.

What a TPMS Does for Your Vehicle

A TPMS monitors air pressure in each tire and alerts drivers when one or more tires become significantly underinflated.

By maintaining properly inflated tires, it helps improve fuel economy, braking stability, and overall tire health, while reducing risks such as excess heat buildup and uneven wear. Modern tire pressure monitoring systems comply with TREAD Act requirements and provide real-time safety alerts during driving.

Direct vs. Indirect TPMS Technology

Direct TPMS uses individual pressure monitoring sensors inside each wheel to deliver accurate air-pressure data and fast low-pressure warnings.

Indirect TPMS relies on wheel speed sensors to estimate pressure changes through rotational differences. While both detect underinflation, direct TPMS offers more precise data, quicker response, and fewer false alerts during tire rotation or cold-weather changes.

Key Indicators of Low Tire Pressure or System Malfunction

The tire pressure light on the dashboard activates when underinflation is detected in one or more tires.

Cold temperatures, air leaks, corrosion, or low sensor battery can trigger warnings. A flashing TPMS light often indicates a system malfunction, meaning the vehicle can no longer measure tire pressure reliably. Prompt action helps avoid reduced fuel economy and compromised handling.

When to Replace or Service TPMS Sensors

Most TPMS sensors last 5–7 years before battery performance declines.

Inconsistent readings, repeated alerts, or a persistent malfunction light are common signs that pressure sensors need replacement or service. Proper maintenance ensures accurate data, stable signal transmission, and continued compliance with vehicle manufacturer standards.
