Tyres provide their maximum level of grip when heated to within a certain temperature range. Finding out if your rubber is getting up to temperature, heating up evenly or over-heating due to lockups, mis-balanced brakes, tyre pressures or poor setup is therefore a massive advantage.
By using our infrared tyre temperature monitoring kit you can easily see how your tyres accumulate and dissipate heat during a lap, giving you a clear picture of what is happening.
The RACELOGIC Tyre Temperature Monitoring System (RLVBTTMS-M) consists of four 120° FOV tyre temperature sensors and a VBOX Touch display for the visual representation of the tyre temperature.
The display shows the whole surface temperature for all four tyres via 64 individual heat maps, as well as live temperature and maximum temperature values.
Each sensor can measure up to 16 temperature points on an object with surface temperatures ranging from -20° C to 300° C.
2022 British GT4 championship winners, Steller Motorsport, use the VBOX Tyre Temperature Monitoring Sensors to increase tyre longevity and boost performance. Talking to Max Daymond, Technical Director at Steller Motorsport, we find out how the team got on using the VBOX TTMS kit and their plans for next season's racing.
Tyre performance is critical when you consider that the only contact the car has with the ground is a few square centimetres of rubber. The difference between a good and bad tyre setup can be the difference between a podium place and finishing last – or indeed not finishing at all. The whole car configuration distills down to those four small contact areas.
Tyre temperature is the most crucial part of the equation as racing rubber is designed to give the highest grip over a certain temperature range. Therefore, to get the best performance, you have to keep them within this operating window.
The traditional way to monitor this is to take a reading from each tyre as the car comes into the pits. But temperature measured like this is an average of the entire session and whilst it gives a rough idea, it is not ideal and certainly does not show the whole picture.
The only other feedback available comes from the driver, who will impart information based on their seat-of-the-pants impression of the car’s performance whilst at the wheel; only some drivers are good at this, but it is always subjective.
Recognising the problem, Racelogic have introduced a product that gets past the difficulties of tyre setup and allows for precise measurement of temperatures, whilst the car is moving.
Infrared sensors, mounted in the proximity of each wheel, measure the temperature across the width of each tyre and the information is then recorded and displayed in real-time on the VBOX Touch display.
Alternatively, the sensors can be used with a VBOX Video HD2, where the information is recorded and overlaid on the video as a heat map. This makes it possible to understand exactly what is happening to the rubber, at all points of the circuit. As this information is available on the screen/ video, it is extremely easy to interpret and see precisely what is happening.
Until you have seen the data, it is difficult to appreciate how much information you can gain from watching what happens to the surface of the tyre as the various loads change during braking, cornering and acceleration.
Take brake bias for instance, this is traditionally adjusted by driver feel and takes a fair amount of experience and car sensitivity. With the fast reacting temperature maps displayed on the screen/ overlaid on the video, you can instantly see which tyres heat up first during the braking phase and tweak the front to rear balance to even them out.
As a driver, it is often difficult to work out if you have locked the tyres up, but by watching the heat maps, you can spot when it happens, and on which tyre. This gives really useful data for setting up the suspension as well as the brakes.
Yes, the tyre temperature sensors can also be used with the VBOX Video HD2. In this case the data can be recorded by the VBOX Video HD2 and the heat maps overlaid in real-time on the video.
As this information is available on the video, it is extremely easy to interpret and see exactly what is happening on the test track.
