Tire Temperature Monitoring – Is 1 Sensor Enough?

September 9, 2025 Off By RICHARD

This article deals with the logistics of 1 sensor tire temperature monitoring and how it compares to monitoring two/four tires at the same time.

Luxury

Getting temperature information from 2 or 4 sensors at the same time is obviously “nice” but in most cases, it’s also a luxury and possibly confusing.

Imagine

We arrive at our test session.

We have what we think is a good baseline geometry setup on the car but we think there is time to be had with a bit of optimisation.

We are using 4 tire temperature sensors and an in-car display for the driver showing the temps.

Issue 1

The driver has arguably got too much data to look at. Perhaps the driver can focus on the one tyre temp but in that case why have four sensors?

Issue 2

We are only going to make one adjustment to the car at a time. It’s nice to see data from all four sensors but the reality is we are only going to be adjusting one corner/axle at a time.

Make the changes, get the temp to where we want it and then start the process again for the other axle. We are not going to be making changes to the front axle and rear axle at the same time.

Key Wheel Temperature Monitoring

Ultimately our primary focus is on the wheel that takes the most stress (eg left wheel on clockwise circuits). This wheel is going to dictate the geometry on the other wheel (on symmetrical setups).
