The world-leading tire pressure monitoring system.
A smarter software for future cars
75% of failing tires are caused by or slow leakage, and tire problems are the third most common reason for passenger vehicle breakdowns. With every 0.2 bar the tire is underinflated, fuel consumption increases 1.5% and the life span of a tire decreases 15%. Approximately 20% of all passenger cars have tires which are underinflated by up to 40%.
TPI by NIRA is a software solution which determines the tire inflation pressure from the wheel speed signals. That means it does not require any in-wheel pressure sensors and RF components. Which, of course, makes it very cost-effective. Thanks to its AUTOSAR compliant interface, TPI can also be quickly and easily integrated with various systems running on different hardware. Moreover, it fulfills all current TPMS legislations worldwide, including ECE-R64 and FMVSS138.

Tire Pressure Indicator by NIRA
- The number one iTPMS on the market – over 100 million units in production
- Complies to all TPMS legislations worldwide with only two variants – one for R141 and one for FMVSS138/GB26149- 2017 Cat.II.
- Autosar-compliant, easy to integrate - default in ESC, in other ECUs possible
- Many reference ESC series integrations with Bosch, ZF and Conti
- No hardware – minimum complexity throughout the whole chain from development to dealership/workshop
Tire Pressure Indicator UX
TPI is capable of detecting pressure drops in one, two, three, or even up to all four tires, and it can also isolate which tires, exactly, are underinflated. The system is robust against surface changes, load variations and driving styles, and it automatically adjusts to different types of tires.
With the introduction of TPI UX we are offering enhanced detection performance and improved graphical interface for increased safety and performance. By utilizing the percentage display, drivers are always well-informed, resulting in fuel savings and increased tire lifespan.
