OnTrack External Tyre Valve Cap TPMS Sensors (Pack of 4)
Take complete control of your tyre performance with the OnTrack External Tyre Valve Cap TPMS Sensors, developed specifically for track day enthusiasts, racers and performance drivers who demand instant access to critical tyre data. Featuring ultra-fast refresh rates, Bluetooth Low Energy (BLE) connectivity and seamless integration with the OnTrack App, this advanced Tyre Pressure Monitoring System (TPMS) delivers accurate, real-time tyre pressure and temperature readings to help you maximise grip, consistency and safety on every drive.
Unlike conventional TPMS systems designed primarily for road use, the OnTrack system has been engineered with motorsport in mind. The lightweight external sensors install in minutes by simply replacing your existing valve caps, making them the ideal solution for drivers who want professional-level tyre monitoring without removing the tyres or wheels.
Whether you're fine-tuning tyre pressures between sessions, chasing faster lap times or simply protecting your tyres during spirited road driving, the OnTrack External TPMS System provides the live data needed to make informed setup decisions.
Designed for Fast, Simple Installation
The OnTrack External TPMS Sensors fit directly onto your existing tyre valves, replacing the standard valve caps with compact wireless pressure and temperature sensors.
Installation takes just a few minutes with no tyre removal, specialist tools or wheel disassembly required. This makes them perfect for enthusiasts looking for a portable monitoring solution that can easily be transferred between compatible vehicles.
Despite their compact size, each sensor has been engineered for the demanding conditions of motorsport and performance driving, providing dependable operation even during extended track sessions.
Real-Time Tyre Pressure & Temperature Monitoring
Every sensor continuously measures tyre pressure and internal operating temperature before transmitting the information directly to the OnTrack App via Bluetooth Low Energy (BLE).
This allows drivers and engineers to monitor each tyre
individually throughout every session and quickly identify:
- Pressure increases as tyres reach operating temperature
- Pressure loss caused by punctures or valve leaks
- Uneven tyre temperatures
- Pressure variations caused by changing track conditions
- Tyres operating outside their optimum pressure range
Having live data available allows quicker adjustments in the paddock while helping maintain maximum grip, predictable handling and consistent lap times.
Lightning-Fast Refresh Rates
Unlike many conventional TPMS systems, the OnTrack system has been engineered to provide exceptionally fast refresh rates, delivering near real-time updates throughout your session.
Rather than relying on outdated pressure readings, drivers receive continuously updated information, allowing tyre pressures to be optimised as conditions change throughout the day.
Whether you're chasing a personal best or competing in endurance events, every PSI matters.
Bluetooth Low Energy Connectivity
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.
Built for Track Days and Motorsport
Correct tyre pressures have a significant impact on grip, braking performance, steering precision and tyre wear.
The OnTrack External TPMS System provides the information needed to optimise tyre pressures before, during and after every session, helping drivers achieve greater consistency while reducing unnecessary tyre wear.
Ideal for:
- Track day enthusiasts
- Motorsport competitors
- Racing professionals
- Performance car owners
- Driver coaching
- Time attack
- Sprint events Hill climbs
The OnTrack External 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. 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 and advanced motorsport-focused monitoring features directly from their smartphone.

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.
