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.

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

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.
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.

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

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.
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.
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.
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.
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.
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.
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.
