       performance and mileage. With this new product line, we wanted to bridge the gap between sustainability and reality
in daily operations.”
Efficient and long-lasting performance
As a new standard tyre fitment for new trucks, the range covers a variety of haulage applications while supporting manufacturers in further lowering
emissions levels of new heavy-duty-vehicles by 2%, on average, in comparison with a C-label tyre for fuel efficiency.
Maciej Szymanski, marketing director Commercial Business Unit Europe at Goodyear, notes: “A reduction of 2% in CO2 emissions translates into a saving of about 1 tonne CO2 and 400 litres of fuel per truck, per year.
“If a 100-vehicle fleet switches from a C-label to a fuel-efficient B-label tyre like Fuelmax Endurance, this would represent a potential saving of 100 tonnes of CO2 emissions and 40,000 litres of fuel, per year. You can imagine the potential when we start multiplying the numbers of vehicles and fleets.”
Key development focus areas
Goodyear says its engineers focused on bridging three conflicting areas of the development spectrum to secure fuel efficiency and low emissions versus 1. mileage, 2. traction and 3. versatility.
The development of the new product line is based around demonstrated Goodyear technologies, with customised innovations for the steer and drive axle positions added to boost fuel efficiency capabilities to a wider range of routes, while safeguarding traction, grip and mileage trough a robust, versatile design.
The Fuelmax S Endurance steer tyre combines Goodyear’s proven IntelliMax Rib Technology in a 5- or 6-rib design.
The stiffeners in the shoulder grooves connect when the tyre rolls, increasing the robustness of the tyre and limiting wear in more demanding off-motorway journeys, where stop-start driving, curb stone impact, increased turning and manoeuvring and more braking put additional demand
on tyres.
The increased tread depth on selected
steer sizes results in more wearable rubber, providing better grip later in the service life. An innovative low energy-loss tread compound offsets heat generation caused by load forces on the steer position. Several steer tyres also feature an optimised sidewall compound, further contributing to lower emissions and fuel efficiency as it
decreases flexion and deformation of the sidewall in off-motorway operations.
In addition to the tread compound for use on the drive axle, the drive tyre benefits from a dedicated curing process to further optimise rolling resistance. The directional tread design includes a high number of deep sipes, deep centre grooves and more biting edges to improve traction and evacuate water more effectively.
Both steer and drive tyres feature the 3PMSF certification and are equipped with RFID, enabling connected tyre management.
Circular economy commitment
The new Fuelmax Endurance range is also compatible with Goodyear’s Retreading program. The drive tyre will be available as a premium TreadMax moldcure retread, adding extra mileage while providing the same features and benefits as the new innovative tread and reducing tyre costs up to 30%.
In combination with Goodyear’s smart tyre monitoring solutions – including Goodyear TPMS, Drive-Over-Reader and DrivePoint – the service life and fuel efficiency can be significantly enhanced.
