Digital Tire Pressure and Temperature Gauge – The main features

In the world of motorsport, where every second counts, every detail of the vehicle must be perfect. Improper setup can cost several seconds on the track, making the difference between first and fifth place. One of the most important aspects is tire pressure. Tire pressure sets a balance between rolling speed, traction, and corner speed. Low pressure allows having a good traction, while high tire pressure provides high rolling speed but a low feeling in the corner. This is where digital tire pressure gauge joins in.

Therefore, it is important to use an accurate digital tire pressure and temperature gauge. Accuracy is one of the main features that the tire pressure gauge must have to ensure a correct pressure measurement. For example, in the motorcycle categories, where we are the technical partner of many teams involved in the World Superbike and Moto GP Championship, measuring an incorrect tire pressure can compromise performance on the track and also put the rider in an unsuitable setup. One of the main features of our Digital Tire Pressure Gauges HPM4 is the ability of the instrument to automatically perform the calibration at each start; if the parameters are not correct, the gauge automatically stops the measurement to avoid giving a wrong pressure measurement.

The tire pressure is an indication of how the tire is working on the track, while the temperature measured at the three characteristic points of the tread (external, intermediate, and internal) tells us its footprint on the asphalt. Having an accurate digital tire gauge for measuring tire pressure and temperature allows you to quickly make measurements when the vehicle returns to the pits after the race or test session.

Tire pressure is typically measured in pounds per square inch (PSI) or BAR. PSI is the most common standard to measure air pressure in motorsport, while BAR is used especially in Europe. One PSI is approximately 0.0068 BAR.

All HiPreMa 4 Digital tire pressure gauges can be switched between PSI and BAR, depending on how you prefer to measure your tire pressure. Digital tire pressure gauges are the most used instruments in motorsport, as they allow for accurate tire pressure measurement.

Things to keep in mind when choosing a quality digital tire pressure gauge

– Digital tire pressure gauge range

One of the most important features of pressure gauges is the pressure range. In tire pressure gauges, a very wide range does not affect accuracy.

In motorsport, tire pressure ranges from a minimum pressure of 0.5 BAR, for example in go-karts, to a tire pressure of about 2/2.5 BAR for some types of tires, such as rain compounds. It is better to use a digital tire pressure gauge with a wide range of pressure; for example, when the tires are mounted on the rims, it is possible to have very high pressures. A tire pressure gauge with a very low measuring range could be damaged if subjected to a pressure outside the maximum pressure range.

– Digital tire pressure gauge resolution

The resolution of tire pressure measurement is the minimum pressure variation that the pressure gauge can measure. This is a very important feature when deciding to purchase an accurate tire pressure gauge. The higher the resolution, the more accurate the measurement will be. Prisma Electronics digital tire pressure gauges HiPreMa 4 have a measurement resolution of 0.01 BAR and 0.1 PSI.

– Digital tire pressure gauge accuracy

The main feature of a digital tire gauge is to be as accurate as possible. All Prisma Electronics digital tire pressure gauges offer an accuracy of measurement of 0.1% over the complete pressure range 0-5 BAR (0-72 PSI). Additionally, all Prisma Electronics pressure gauges do not require calibration; you can always be sure to use an accurate instrument.

All models include a backlight display, date and time showed on the display and saved for each session, air temperature and the possibility to save COLD and HOT tire pressures and their difference in order to have immediately an evaluation of the balance of the vehicle.

– Digital tire pressure gauge durability and reliability

It is important to choose a tire pressure gauge that is durable and reliable, as it will be subjected to rough conditions on the track and in the pits. All Prisma Electronics digital tire pressure gauge guarantee high durability and reliability.

– Ease of use

A digital tire pressure gauge should be easy to use, with clear and concise instructions and a user-friendly interface. It should also have features such as a backlight display and the ability to save tire pressures for easy reference: just like our devices.

– Tire compound temperature measurement

In addition to tire pressure, one of the most important parameters for understanding and optimizing tire performance is their operating temperature. It is important that the tire compound temperature is within the correct values in order to optimize the mechanical grip and keep tire wear under control. By measuring the compound temperature at the three different points of the tread (internal, intermediate, and external), it is possible to have an idea of the tire’s footprint on the asphalt.

– Tire compound temperature range

The temperature of racing tires has a very narrow window of use. Deviating from these ideal values by just 5°C can compromise the performance of the tire compound. It can be said that a tire temperature gauge must be optimized for a range of values ranging from +70°C to +120°C.

– How to measure tire compound temperature

It is possible to measure the tread temperature of a tire using two types of temperature gauges: non-contact temperature measurement and contact temperature measurement.

– Non-contact Temperature measurement

This category includes infrared pyrometers, where the temperature is measured at a certain distance from the object to be measured.

– Contact Temperature measurement

This category includes tire pyrometers with needle probes, where the temperature is measured by the contact between the instrument and the object to be measured.

– Air and track temperature measurement

Two temperatures play an important role in motorsport: air temperature and track temperature. While they are connected, they are not the same. For example, on a sunny day, both air and track temperatures will rise. As soon as cloud cover arrives, the air temperature will drop immediately, but the track will retain the heat over a longer period of time and cool down slowly.

Variations in temperature impact many parts of the car or bike, but the biggest influence is usually on the tires. The track temperature impacts how hot the tires will run, which will in turn impact the grip level and the degradation rate. For this reason, all the temperature gauges of the HPM4 product line have the ability to measure and store the air and asphalt temperature for each session.
