Introducing safe, reliable, wireless and continuous tyre pressure monitoring
For a steer axle with a 12,000-lb. rating, commonly-accepted pressure is 110 psi, and most drivers assume 85 psi is okay. But for every 10% of underinflation, you’re looking at a 1% reduction in fuel economy. Multiply that by the miles you travel in a year and you can expect:

Underinflation or improper psi might seem like an insignificant problem, but spread across a modern fleet, it can yield some surprising challenges.
- 30% loss in tread life for tyres underinflated by 20%
- 40% loss in tread life for tyres underinflated by 30%.
But that’s just the beginning . . .
In the past, truckers have tried to get in the habit of getting out of their rigs throughout the day to check a calibrated gauge on each tyre’s value stem.
That approach can cost time and money—especially if it isn’t part of a routine for all drivers in a fleet.
Then there’s the concept of establishing each tyre’s “ideal pressure.” Even if that was possible (e.g. 110 psi on a 12,000-lb front axle), you still need to:
- Set drive and trailer tyre pressure within a broader allowable range
- Prevent overcompensating for temperature changes
- Prevent overcompensating for gross-vehicle-weight changes
- Manage hazardous road conditions
As a result, many fleets determine recommended tyre pressure based on worst vehicle load. Unfortunately, because loads vary by wheel position, fleets often try to solve the problem through complicated load/inflation tables.
Bottom line: fleets will continue to lose tyres—and profits—due to:
- Negligence and apathy
- Under-inflated tyres
- Mechanical problems
- Improper tyre selection
With the SKF Tyre Pressure Monitoring System:
- Drivers monitor tyre pressure accurately and continuously to improve fleet safety and efficiency.
- Tyre pressure data, sent wirelessly from external wheel modules, works with each vehicle’s internal communication network to give drivers real-time tyre pressures.
The results help drivers:
- Eliminate tyre-related accident risks
- Minimize unplanned vehicle downtime
- Cut fuel consumption and operating costs
How rigs and fleets benefit:
- Reduce the risk of blowouts and unplanned downtime
- Improve tyre life and lowers total cost of ownership
- Improve fuel economy and safety
- Reduce CO2 emissions
External wheel modules mount on each wheel rim to transmit tyre pressure and temperature data:
- Wirelessly
- Accurately
- Continuously
Electronic control unit receives tyre condition data, while the exclusive, SKF algorithm:
- Uses pressure and temperature data for calculations
- Provides reliable information to the driver

The braking system is one of the most critical components of a vehicle and has a direct impact on safety. Among the various elements within this system, brake pads are crucial. They ensure that the vehicle stops safely and effectively, making the choice of high-quality pads essential. With more than a century of experience, SKF excels in the development of OE and Aftermarket solutions, including brake rotors with integrated bearings, and offers nearly 900 different brake pad sets for different applications.

We are used to driving our cars with the only concern being when we we need to schedule regular maintenance, but there are some dangerous issues we can avert from happening just by being aware of some not-so-subtle symptoms.

The wheel bearings on your car can last a lifetime or may not last very long. It all depends on several aspects that we will discuss below. Before talking about replacing wheel bearing, let’s take a quick look at what can cause it to fail.

It is not necessary to replace both at the same time, however, it is highly recommended due to a high risk of engine damage. All parts of the synchronous drive have the same mileage and wear. If one of the parts is not replaced and loaded again by the timing belt adjustment, this can lead to a failure after a short time. Also, this could save money in the long run as the mechanic only has to do the work to get to the synchronous drive once.

The timing system is a crucial part of the four-stroke internal combustion engine. Its components drive the synchronized rotation of the camshaft(s), ensuring the engine’s inlet and outlet valves open and close at the proper times. This means that if any of the timing components fail, the car will no longer operate properly, which can cause costly damage to the engine.

Driveshafts transfer engine torque from the gearbox to the wheel hub at a constant rate, without friction variations or play in cars equipped with an independent suspension system. Driveshafts need to bear stress without creating additional inertia dur to their weight.

When checking a water pump, you might be confused by the coloured spot on the water pump reservoir. This tinted spot is often associated with coolant leakage; however, it is necessary to make sure that this is not a natural leak. There are several ways to check if the leak is natural. If you're a mechanic, the easiest way is to use a pressure tester like the Cooling System Test & Refill Kit MV4525 from Mityvac. The new patented technology combines simultaneous testing and monitoring of pressure, vacuum, and temperature, providing real-time data that goes far beyond the capabilities of a simple pressure tester.
