Managing racing tires is a complex job.

Good race teams know what the ideal tire temperature is. Pretty much the same can also be said for the tire pressure. Small increases or decreases of tire degrees have a considerable impact on the CAR or BIKE balance.

Racing tires have a very narrow operating window. Operating below this windows doesn’t produce the same levels of mechanical grip or performance, while being above it can cause performance to drop and increase tire wear

What is your best tire temperatures ?  And at which pressure ?
To understand this two most important things on your vehicle setup you need an accurately tire pressure gauge and tire pyrometer.

We have designed an instruments that joint tire pressure gauge and tire pyrometer. You can measure and save all your tire parameters.


Digital tire pressure gauge and tire pyrometer


Thanks to the high accuracy needle tire probe, you can measure and save the tire compound temperature in the three different characteristic points.

Pressure and Temperature of the racing tires

Useful when you want to understand the effect of the CAMBER and CASTER in cars and also the temperatures in the different lean angles of the bikes.

Pressure and temperature effects on bike tire

It is possible to evaluate the dynamic setup of the vehicle through the evaluation of temperatures in the different points of the tires.

Saving tire pressures in the pressure gauge MODE

Measure and save the COLD and HOT tire pressures in the PRESSURE mode. The display shows the pressures difference, the TIME - DATE and AIR temperature for each session.


Tire Pyrometer MODE

  • 12 Points of tire temperature
  • AIR temperature
  • TRACK temperature

Saving tire temperatures in the Pyrometer MODE

By pressing MODE button it is possible to switch to TEMPERATURE MODE. Measure and save AIR and TRACK temperatures and 12 points of tire temperature ( ex. EXTERNAL - INTERMEDIATE - INTERNAL ) for each sets.


After taking tire pressures and temperatures, you can see the values that were recorded.
