Following manufacturer’s indication on tyre pressure levels is a very critical and vital task to keep up with. The air pressure in tyres supports the entire weight of the bus, and this calls for a regular monitoring of the vehicle’s tyre pressure levels. This will help in maintaining the correct tyre pressure that will help in keeping you, persons on board and other road users safe. Correct tyre inflation improves the vehicle performance; cuts fuel costs and ensures that you are receiving the most lifespan out of your bus tyres. When considering tyre maintenance, the type of bus tyre used cannot be overlooked.
“The air inside a tyre carries the load of the vehicle. Underinflation causes damage to the side-wall of the tyre, increases heat build-up, and eventually a tyre failure,” says Lee Demis, Vice President of Business Development at Doran Manufacturing.
How Bus Tyre Pressure Affects Handling, Safety, and Fuel Consumption
Proper bus tyre pressure significantly improves vehicle handling, enhances passenger comfort and safety, strengthens braking performance, and greatly reduces fuel consumption. An incorrect inflation pressure level intensifies the fuel consumption, escalates the rolling resistance of tyres that could lead to an unfortunate incident. Furthermore, the quality and condition of the bus tyre directly influence overall operational efficiency.
“Proper tyre inflation pressure is critically important for safe operation of buses. Just recently, a bus crash in the United States injured 12 people when a tire blew out. The driver lost control of the vehicle, and the bus landed on its side,” says Demis. “Thankfully, everyone survived this incident,” he clarifies.
Additionally, according to Andre Gerken, General Manager at Celerity DRS GmbH, the correct tyre inflation has a huge impact on the road safety and operating costs of a vehicle. “Consider that the tyres are the only connection between the vehicle and the road. Therefore, a wrong tyre pressure can directly influence the handling and the brake performance of the vehicle. With a low tyre pressure more of the tyre surface contacts the road, which increase the drag and the result is a higher tyre wear and fuel consumption,” articulates Gerken. Notably, consistent care of each bus tyre is essential for optimum safety and cost control.

The Tyre Pressure Monitoring Systems (TPMS)
Drivers often overlook tyres, and this neglect can lead to fatal road accidents, property damage, and loss of life. However, tyre pressure monitoring systems (TPMS) significantly reduce these risks by detecting pressure and temperature issues early, helping prevent vehicle damage, accidents, and loss of life. Incorporating TPMS systems for every bus tyre can provide enhanced detection capability for safety.
“Tyre pressure monitoring systems can monitor both pressure and temperature, and alert drivers to underinflation and critical high temperatures before catastrophic tyre failures occur. Bus operators can improve the safety of their vehicles and improve the efficiency of their fleet by properly utilizing TPMS,” counsels Demis.
“With the help of a tyre inflation system, the correct pressure can be always ensured, while stationary or in transit,” adds Gerken.

Dual Tyres and the Hidden Risk of Underinflation
Conferring to Paul Webber, the General Manager of Mavtech, under inflation becomes an especially serious problem when the inside tyre of a set of duals begins losing pressure. In some cases, both tyres fail with very dangerous consequences. Webber further elaborates on the importance of proper bus tyre inflation and its impact on the vehicle safety and handling performance. Dual bus tyre sets can carry hidden risks when underinflated.
i. Better tyre mileage
Improper inflation accounts for 80% of re-tread separations, cuts, bruises, flats and blowouts. Under inflation of only 5 PSI reduces tyre life by a shocking 25%. To maximize longevity, each bus tyre must be properly inflated.
ii. Less down time
Tyre Pressure System virtually eliminates the need for costly road service calls and expensive down time. If a tyre is punctured, the tyre pressure system continues to inflate it while simultaneously alerting the driver to the issue. He’s then aware of the situation and can continue on to his destination or plan to stop for service. In particular, for bus tyre maintenance, this reduces downtime effectively.
iii. Better fuel economy
For every PSI of under inflation, your vehicle consumes 0.8% more fuel. Talk about giving your budget a boost! Having properly inflated bus tyre sets helps save on fuel expenses.
iv. Increased safety
Under inflated tyres is a major cause of truck and bus accidents on highways. Proper inflation is the most important requirement for maximum tyre safety. Correct tyre pressure provides proper sidewall flexing and safe operating temperature of the tyres. Keeping every bus tyre at the right pressure level increases highway safety.
Commercial vehicles, such as trailers, trucks, buses and coaches face constant operational challenges due to varying duties and frequent load changes throughout a typical day. Tyres play a critical role in ensuring smooth and reliable bus operation, and they cannot perform as designed when operators use incorrect air pressure. Both underinflated and overinflated bus tyres compromise safety and significantly increase operating costs. To avoid these risks, it’s important to routinely check every bus tyre for pressure accuracy.
As a core safety and performance component, operators must maintain correct tyre pressure at all times, whether the vehicle is parked or in motion. Proper inflation supports consistent performance regardless of load, speed, or road conditions. Most importantly, correct bus tyre pressure protects passengers, pedestrians, and other road users. Maintain the right tyre pressure at all times to ensure safety, efficiency, and reliability. In summary, focusing on bus tyre care is essential for performance and safety on the road.
