Tyre Pressure Monitor
External Tyre Valve Cap TPMS Sensors (Pack of 4)
Monitor your tyre pressures and temperatures with confidence using the OnTrack External Tyre Valve Cap TPMS Sensors. Originally developed for track days, motorsport and high-performance driving, these lightweight Bluetooth® sensors are equally at home on the road, allowing everyday drivers to monitor tyre pressures and temperatures in real time to improve reliability, safety, tyre life and overall driving confidence.
Replacing your existing valve caps, the external sensors install in minutes with no tyre removal or specialist tools required. Once paired with the free OnTrack App, they provide fast, accurate, real-time pressure and temperature readings for all four tyres, helping you identify pressure loss, uneven temperatures and changing tyre conditions before they become a problem.
Unlike many conventional TPMS systems, OnTrack delivers ultra-fast refresh rates via Bluetooth Low Energy (BLE), allowing you to monitor tyre performance live whether you're chasing lap times on circuit, enjoying a spirited weekend drive or simply keeping your Porsche's tyres at their optimum pressure during everyday use.

The OnTrack External TPMS Sensors communicate wirelessly using Bluetooth Low Energy (BLE) technology, providing fast, reliable communication with the dedicated OnTrack App while maintaining excellent battery efficiency.
The intuitive app allows users to:
- View live tyre pressures
- Monitor tyre temperatures
- Display all four tyres simultaneously
- Set custom pressure alerts
- Set temperature warnings
- Monitor tyre performance throughout every driving session
The free app is currently available for iOS, with Android compatibility coming late Summer 2026.
OnTrack Internal TPMS Sensors (Pack of 4)
Take complete control of your tyre performance with the OnTrack Internal TPMS Sensors, developed specifically for track day enthusiasts, racers and high-performance driving. Engineered to deliver exceptionally fast refresh rates and highly accurate tyre pressure and temperature monitoring, these internal wireless sensors provide the real-time data needed to maximise grip, consistency and driver confidence on every lap.
Unlike conventional TPMS systems designed primarily for road use, the OnTrack system has been developed with motorsport at its core. Every sensor continuously communicates with the OnTrack App, allowing drivers and engineers to monitor tyre pressures and temperatures live, helping identify critical changes before they affect handling or lap times.
Whether you're fine-tuning tyre pressures during a track day, analysing performance between sessions or competing in motorsport, the OnTrack Internal TPMS System delivers the speed, accuracy and reliability needed to make informed setup decisions.
Developed for Track Performance
Correct tyre pressures are one of the biggest contributors to vehicle performance. Even small pressure changes can dramatically affect grip levels, steering response, braking performance and tyre wear.
The OnTrack Internal TPMS Sensors provide near real-time updates, allowing you to monitor each tyre individually throughout every driving session. This enables quicker adjustments in the paddock and helps maintain optimum tyre operating conditions for maximum performance.
Unlike slower factory TPMS systems, the OnTrack sensors have been engineered for rapid data transmission, ensuring you always have the latest tyre information available when it matters most.
The OnTrack Internal TPMS Sensors are designed primarily for vehicles without a factory-fitted TPMS system.
They can also be installed on vehicles equipped with an original factory TPMS; however, the tyre pressure and temperature data will be displayed exclusively through the OnTrack App. The sensor readings will not integrate with or display on the vehicle's original TPMS display or instrument cluster.
This allows owners of factory-equipped vehicles to benefit from the OnTrack system's fast refresh rates, real-time pressure and temperature monitoring, and advanced track-focused features via their smartphone.
Real-Time Tyre Pressure & Temperature Monitoring
Using advanced wireless sensor technology, each internal sensor continuously measures both tyre pressure and internal tyre temperature before transmitting the information directly to the OnTrack App.
Live monitoring allows drivers to quickly identify:
- Pressure increases as tyres reach operating temperature
- Pressure loss from punctures or valve leaks
- Uneven temperature distribution across the vehicle
- Changes caused by driving style or track conditions
- Tyres operating outside their ideal pressure window
Having this information readily available allows faster setup adjustments, improving consistency throughout the day while helping maximise tyre life and overall performance.
Lightning Fast Refresh Rates
The OnTrack TPMS system has been designed to provide exceptionally fast refresh rates, giving drivers and engineers near-instant feedback throughout each session.
Rapid updates mean you're no longer relying on outdated tyre data between laps. Instead, you receive continuous information that helps optimise tyre pressures for changing track conditions, ambient temperatures and driving style.
Whether you're chasing your fastest lap or preparing for endurance events, every second counts—and so does every PSI.
Designed for Motorsport
Every component has been engineered to withstand the demanding environment of circuit driving.
The internal wireless sensors are protected inside the wheel, shielding them from damage while delivering accurate measurements under high-speed cornering, heavy braking and elevated tyre temperatures.
Ideal for:
- Circuit racing
- Track days
- Time attack events
- Hill climbs
- Sprint events
- Driver coaching
- Performance road cars
Seamless App Integration
The OnTrack TPMS system works seamlessly with the dedicated OnTrack App, providing an intuitive dashboard for live tyre monitoring.
The app allows users to:
- View live tyre pressures
- Monitor tyre temperatures
- Track all four tyres simultaneously
- Receive customisable pressure and temperature alerts
- Quickly identify developing issues before they affect performance
- Analyse tyre behaviour throughout each driving session
The free app is currently available for iOS, with Android compatibility scheduled for late Summer 2026.
Improve Performance and Safety
Correct tyre pressures are critical for achieving predictable handling and consistent lap times.
Running pressures too low can cause excessive sidewall movement, increased temperatures and accelerated tyre wear. Excessively high pressures reduce the tyre's contact patch, compromising grip and braking performance.
With live tyre monitoring, drivers can quickly make informed
adjustments, improving:
- Cornering grip Steering precision
- Braking stability
- Tyre longevity
- Lap time consistency
- Overall vehicle balance
The system also enhances safety by providing immediate warnings if abnormal pressure loss or excessive tyre temperatures are detected.
Package Contents
Each kit includes:
- 4 x OnTrack Internal Wireless Tyre Pressure & Temperature Sensors
- Free OnTrack App Download (iOS Compatible)
- Android App Coming Late Summer 2026
