High Precision Tire pressure gauge with Tire probe Pyrometer


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

Measure and saves the temperatures in three different characteristic points of the tire


Thanks to the high accuracy needle tire probe, you can measure and save the tire temperatures of the tread.

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.

Technical Features
CAR and BIKE setup

By the MENU' you can set BIKE or CAR vehicle type - 2 Wheels or 4 Wheels.


By activating this function the pressure gauge HIPREMA 4 save automatically the HOT tire pressures without pressing any buttons.

  • BAR and PSI for tire pressure gauge
  • CELSIUS and FAHRENHEIT for air temperature
PRESSURE gauge accuracy : 0.1%
  • Maximum error at 5 BAR : +/- 0,005 BAR -- ( 0.072 PSI )
  • Maximum error at 1 BAR : +/- 0,001 BAR -- ( 0.014 PSI )
  • Tire pressure gauge HPM4 does not require calibration. The internal microprocessor automatically performs the procedure in order to reach a reliable measure at 100%.
