The probe is low thermal mass which won’t act as a heat sink to skew your readings (unlike metal bodied probes).

 

Quick response: After insertion it typically takes 2 seconds for the probe to reach 90% of the final temperature, 3 seconds for 95% and 4 seconds + for the temperature response to level out.

The gauge even shows Up or Down arrows if the temperature is changing. 

These will disappear when stable.

Adjustable depth: There is a screw adjuster and locking nut so that the tyre can be probed at a consistent depth. 

A depth of between 3 and 5mm is recommended. 

The probe can be adjusted up to 15mm which will puncture most tyres. 

To avoid punctures the needle should obviously not be inserted too deep and the probe should be inserted into the tyre blocks only and not the grooves/voids or sides. 

Take care with very worn tyres.

Avoid heat sources: Temperature accuracy will be affected if e.g. the gauge or probe are heated (or cooled). 

So, do not leave the gauge and probe near sources of heat or where large thermal gradients may be expected e.g. in direct sunlight, on top of engine, near heaters or fans etc.

Car setup, tyre pressures, track conditions and driving style will all affect the bulk tyre temperatures.

It does not make sense to compare readings from different car or tyre types or different probe depths.
