Take a closer look at the 4 reasons to use TPMS on a truck.
.
In this article, we will consider the four main advantages of using pressure sensors on trucks.
1
Safety
According to statistics, 56 out of 300 accidents on the highway occur due to a tire rupture. Thus, the cause of accidents in 19% of cases is improper tire operation.
Accidents caused by a ruptured tire are regularly included in traffic accident reports. On February 27, 2022, a burst truck tire led to a fatal accident on the M-4 Don highway. The driver lost control and the truck drove into the oncoming lane after the tire burst. This is, of course, a fatal example. More often there is a situation when the unsatisfactory condition of the tire indirectly leads to an accident: it makes the car less stable, increases its braking distance.
Monitoring and timely response to changes in tires thanks to the tire pressure monitoring system will help to avoid adverse situations during truck movement, increase safety, as well as avoid downtime of the fleet.

Reduced fuel consumption
An analysis of the effect of tire pressure on rolling resistance and, as a result, on fuel consumption showed that a decrease in tire pressure always leads to an increase in fuel consumption. For example, reducing the pressure in truck tires by 0.05 MPa increases fuel consumption by 5%.
If you take into account the mileage that runs over the year, you can significantly save on fuel by using a tire pressure monitoring system.
3
Extended tire and tread life
Improper tire pressure causes the tire to deform, which in turn leads to uneven tread wear and premature tire wear. Low pressure deforms the tires from the inside in such a way that contact with the road surface occurs only on the outer surface of the wheel. High tire pressure causes the tires to touch the surface only in their middle part. If there is improper contact with the ground, the tire heats up and deforms.
Improper tire pressure can not only lead to uneven tire wear, but also damage the tire carcass and make it impossible to retread. The results of scientific research show that when operating vehicles with low tire pressure, the tire life is reduced by 30%, and according to some estimates even by 50%. Equipping trucks with a tire pressure monitoring system helps transportation companies reduce tire repair and replacement costs.

Saving drivers' time
If the truck is not equipped with an automatic tire pressure monitoring system, then drivers have to regularly check the pressure manually using a pressure gauge. Checking all the wheels on a truck, consisting of 10-18 units, requires considerable time from the driver, entails fatigue. However, the accuracy of the pressure gauge readings is lower than that of the electronic system. The same point can include the time and financial costs of replacing a wheel or calling a repair team in case of a breakdown on the way.
After installing the tire pressure monitoring system, travel time will be reduced, transportation safety will increase and, as a result, the company will profit by it.
Tire pressure sensors reduce fuel and tire repair/replacement costs. Drivers get less tired, and there is a benefit in travel time. All these advantages and the ease of installation of the PressurePro tire pressure monitoring system (sensors are screwed onto the nipple of the wheel in the form of caps) will make your business in the field of cargo transportation more profitable.

What is the point?
One night we met with representatives of the very famous network food company which agreed to provide its transport for the experiment on the City Ring Road. We decided to do our measurements at night in order to avoid traffic jams.
Two MAN TGS 4x2 trucks with the same three-axle semi-trailers were used for the experiment.
Of course, we understood perfectly well that there are no vehicles with exactly the same fuel consumption. Moreover, our trucks were already 4 years old. It is quite a mature age for commercial vehicles that affects fuel consumption as well. But we were not going to compare the fuel consumption between vehicles, we just needed to find how the tire pressure affects it.
We checked and equalized the tire pressure to 8 bars (in cold state), fully refueled the trucks and set up GalileoSKY GPS trackers and PressurePro TPMS.
Both trucks are equipped with KAMA tires with 10% tread wear on the steering axle and around 50% on other wheels.
LET'S GO!
Drivers are ready to go as they got all the necessary instructions. 14 weighed and marked cans of diesel fuel are prepared to refuel the trucks upon return. Electronic scales with an accuracy of 5 grams will allow us to determine the volume of diesel in liters. The first stage is over, the MAN trucks are back.

The first stage is over, the MAN trucks are back. Both trucks covered 142 km with the average speed of 77 kmph but the fuel consumption was different.
The first one was refueled with 33.575 kg of fuel which is 39.5 liters, another one with 35.335 kg (41.57 liters). There is a definite difference.
The fuel consumption is 27.81 and 29.27 l/100 km, respectively.
We let the drivers to take some rest and the vehicles to cool down. Then we check the tire pressure again and make some adjustments.
We decrease the tire pressure only on 4 wheels out of 12 in the driving axle of the first truck down to 6 bar.
These 4 wheels are visually indistinguishable from the others, which are still pumped to 8 bar.
The tire pressure of the second truck remains the same.
Everything is ready for the second lap.
We expect that the fuel consumption of both trucks will change due to the road and weather conditions, driving style, etc. But for the first truck the change will be caused by the decreased tire pressure in the driving axle as well. Here are the results of the second stage.

The mileage and average speed remained the same. But the first truck, which showed the best economy in the first stage, became an outsider this time.
The first truck was refueled with 36.428 kg (42.85 liters) of fuel while the second took 35.875 kg (42.18 liters). So the fuel consumption in the first case increased to 30.18 l/100 km, and in the second case it almost did not change and amounted 29.7 l/100 km.
As a percentage, it looks like + 1.5% for measurement errors and + 8.5% for a decrease in the tire pressure.
As a percentage, it looks like + 1.5% for measurement errors and + 8.5% for a decrease in the tire pressure.
At first, 7% does not seem like a big figure.
But imagine an average transport company with 100 vehicles, covering 100,000 km a year (it is not a big distance for commercial trucks). Taking into account the fact that trucks are heavy loaded and roads are often much worse than the Ring Roads, the fuel consumption will be higher than it was in the experiment, for example, 35 l/100 km. Thus, each truck consumes about 35,000 liters of fuel per year . Multiply it by 100 trucks and increasing prices for fuel. And it does not include losses due to decreases of tire service life and transportation safety. Do you really think you are willing to pay such a price?
