Goodyear launches new bus tyre

Goodyear has launched a new tyre aimed at bus fleets. The UrbanMax MCA HL+ has been designed to help fleet operators maximise efficiency while preparing for the gradual electrification and automation of the industry, according to the tyre maker.

“Bus operators are under increasing pressure to meet environmental targets while adapting to changing trends in urban mobility,” said Goodyear’s commercial marketing director for Europe, Maciej Szymanski. “Our aim is to support bus fleet managers in lowering the carbon footprint by driving energy efficiency with low-emission tires as well as smart tyre monitoring systems.”

The latest MCA HL+ is based on the design of Goodyear’s previous UrbanMax MCA, but features updates to reduce energy consumption and to support the additional weight of electric vehicle batteries.

Furthermore, to reduce CO2 and noise emissions, the tyre maker has introduced a new tread compound that also features an optimised rib layout to ensure even contact pressure distribution, shoulder robustness and stress reduction. The low hysteresis tread helps to reduce heat build-up and provides high levels of traction in poor weather.

Released as an all-position tyre, the UrbanMax MCA HL+ has a high-load structure enabling an eight-ton axle load capacity – a requirement for modern hybrid and electric buses.

Goodyear’s incorporated Interlaced Strip Technology ensures less deformation in the tyre’s carcass and creates uniform pressure distribution.

Flexomatic sipes in the centre ribs are supported by block edge siping to improve braking. Additionally, the Flexomatic sipes close when rolling so that the tread blocks interlock, making the tread stiffer and more robust.

“The UrbanMax MCA is known for its high mileage potential, traction and all-weather grip performance, which are required in demanding urban environments,” said Szymanski. “The new UrbanMax MCA HL+ size offers lower rolling resistance to enhance energy and fuel efficiency as well as an increased load capacity, further supporting range extension for electric buses.”

With buses often coming into contact with curbs, potholes and speed humps in urban areas, Goodyear says it designed the tyre with a reinforced sidewall to minimise vehicle downtime. Wear indicators also give a visual representation of how much of the protective layer remains; the tyre can then be reversed to extend service life.

The UrbanMax MCA HL+ benefits from the 3PMSF sidewall marking, representing its capability on snow and ice. Integrated RFID tags enable tyre identification and connectivity with tyre management and tracking systems and the full range is also compatible with Goodyear’s retreading program.
