HomeFeatures ExplainedTyre Pressure Monitoring System Tpms Feature Explained

Published : 18 June 2026

Read Time : 5 min

A Tyre Pressure Monitoring System (TPMS) monitors tyre pressure and alerts drivers about pressure loss. In this article, we explain how TPMS works, its types, benefits, drawbacks, repair and replacement costs, and whether aftermarket TPMS is worth installing.

Tyre Pressure Monitoring System (TPMS)

What Is A Tyre Pressure Monitoring System?

A Tyre Pressure Monitoring System (TPMS) is an electronic system that monitors the air pressure inside a vehicle’s tyres in real-time. It alerts the driver when tyre pressure drops below a critical level, preventing potential hazards associated with underinflated tyres.

How Does A Tyre Pressure Monitoring System Work?

TPMS utilises sensors, either directly or indirectly, to measure tyre pressure.

  • Direct TPMS: Sensors are mounted inside each tyre, directly measuring pressure and temperature. These sensors transmit data to the vehicle’s onboard computer, which displays the readings on the dashboard.
  • Indirect TPMS: This system uses the vehicle’s Anti-lock Braking System (ABS) sensors to monitor tyre rotation speed. A decrease in tyre pressure alters the tyre’s rolling radius, which the ABS sensors detect. The system then alerts the driver.

What Are The Different Types Of Tyre Pressure Monitoring Systems?

  • TPMS with Display: These systems provide real-time tyre pressure readings for each individual tyre on the vehicle’s dashboard display. They often include temperature readings and allow for more precise monitoring.
  • TPMS with Warning Only: These systems simply trigger a warning light on the dashboard when tyre pressure falls below a pre-set threshold. They don’t provide specific pressure readings.

TPMS

What Are The Pros And Cons Of Tyre Pressure Monitoring Systems?

TPMS pros or advantages:

  • Enhanced Safety: Prevents accidents caused by underinflated tyres.
  • Improved Fuel Efficiency: Properly inflated tyres reduce rolling resistance, improving fuel economy.
  • Increased Tyre Lifespan: Prevents premature tyre wear.
  • Real-time Monitoring: Provides instant alerts to pressure changes.

TPMS cons or disadvantages:

  • Sensor Malfunction: Sensors can fail, requiring replacement.
  • Cost: Direct TPMS systems can be expensive to repair or replace.
  • Battery Life: Direct TPMS sensors have limited battery life.

How Expensive Is It To Repair Or Replace A Tyre Pressure Monitoring System?

The cost of repair or replacement varies depending on the type of TPMS and the vehicle. Direct TPMS sensor replacement can range from Rs. 2,000 to Rs. 5,000 per sensor, plus labor costs. Indirect TPMS repairs are typically less expensive, as they rely on existing ABS components.

Can A Tyre Pressure Monitoring System Be Fixed From The Aftermarket?

Yes, both direct and indirect TPMS systems can be installed or repaired through aftermarket services. However, it’s crucial to choose reputable installers and high-quality components.

Smart TPMS Feature

How Much Does An Aftermarket TPMS Cost?

Aftermarket TPMS systems can range from Rs. 5,000 to Rs. 15,000, depending on the type and features. Installation costs are additional.

How Easy Or Complex Is It To Install An Aftermarket TPMS?

Direct TPMS installation requires mounting sensors inside the tyres, which can be complex and requires specialized equipment. Indirect TPMS installation is generally simpler, as it involves connecting to the vehicle’s ABS system.

What Affordable Cars In India Get TPMS?

Many affordable cars in India now offer TPMS, especially in higher variants. Examples include models from Maruti Suzuki, Hyundai, Tata, and Kia. The availability of TPMS is steadily increasing across various segments.

Some of the most budget-friendly models offering TPMS include:

  • Renault Kwid
  • Tata Tiago
  • Citroen C3
  • Hyundai Exter
  • Nissan Magnite
  • Renault Triber
  • Maruti Dzire

TPMS Feature Detection

Verdict - Should I Get A Tyre Pressure Monitoring System?

Yes, a TPMS is a valuable safety feature as it helps drivers monitor tyre pressure and respond to pressure loss early. Whether it is factory-installed or fitted as an aftermarket accessory, TPMS can improve safety, tyre life and fuel efficiency. If your car does not offer TPMS, an aftermarket system is worth considering. You can also learn how to read tyre markings to better understand tyre size, load rating and speed rating before replacing your car’s tyres.

FAQs

What Is A Tyre Pressure Monitoring System (TPMS)?

A Tyre Pressure Monitoring System (TPMS) is a safety feature that monitors the air pressure in a car’s tyres. It alerts the driver when 1 or more tyres lose pressure. Some TPMS setups also show the exact tyre pressure for each tyre. TPMS helps drivers maintain the correct tyre pressure, which can improve safety, handling, fuel efficiency and tyre life.

Is TPMS Mandatory In Cars In India?

TPMS is not mandatory for all passenger cars in India. However, several carmakers offer it in higher variants, and some cars get it as standard. TPMS is a useful safety feature, but it should not replace regular manual tyre pressure checks.

What Is The Difference Between Direct TPMS And Indirect TPMS?

Direct TPMS uses pressure sensors mounted inside or on the tyre valves to measure tyre pressure. It is more accurate and can show the pressure of individual tyres. Indirect TPMS does not use dedicated pressure sensors. It uses wheel-speed data from the ABS or electronic stability control system to detect pressure loss. Indirect TPMS is usually cheaper, but it is less accurate and may need recalibration after filling air or changing tyres.

Can You Install Aftermarket TPMS In Any Car?

You can install aftermarket TPMS in most cars with tubeless tyres. Aftermarket kits usually come with external valve-mounted sensors or internal sensors fitted inside the wheels. External sensors are easier to install, but they are more exposed to damage or theft. Internal sensors offer a cleaner fitment, but they require tyre removal during installation.

How Accurate Is A Tyre Pressure Monitoring System?

Direct TPMS is generally more accurate because it measures tyre pressure using dedicated sensors. Indirect TPMS is less accurate because it estimates pressure loss using wheel-speed data. Even with TPMS, drivers should manually check tyre pressure regularly, especially before long highway trips.

What Happens If The TPMS Warning Light Comes On?

If the TPMS warning light comes on, 1 or more tyres may have low pressure. Stop safely and check the tyre pressure with a gauge. Inflate the tyres as per the manufacturer’s recommended pressure. If the warning stays on even after correcting the pressure, there could be a puncture, air leak, valve issue or TPMS sensor fault.
