Tyres for electric buses need to support a higher overall vehicle weight due to the heavy electric battery and stand instant torque delivery, according to Continental which has now launched a dedicated product to meet this sector, the Conti Urban HA3 315/60 R22.5.
These all-axle tires feature enhanced grip and a load carrying capacity of eight tonnes per axle, 0.5 tonnes more than the standard for this tyre size, according to the company.
The Conti Urban HA3’s increased load index is due to its robust casing featuring high wire density and thickness. It also has a sturdy, durable tread with a high proportion of natural rubber, which increases resistance to cuts, cracks, chipping, chunking, and abrasion, and should mean a long service life and utilisation of the tyre’s full mileage potential.
A special urban bus tyre contour layout adds to endurance and even wear, while the wide tread width ensures cornering stability and handling for maximum safety in urban traffic. High-density interlocking sipes provide optimum grip and lane holding, even in extremely wet conditions, throughout the service life. The sipes are also staggered in order to reduce noise for increased ride comfort. And reinforced sidewalls ensure that the Conti Urban HA3 reliably withstands frequent kerb contact.
“The new Conti Urban HA3 optimised for electric buses brings to fruition the valuable experience we’ve gathered from our recent collaboration with commercial vehicle manufacturers and municipal bus companies,” says Lutz Stäbner, head of product management for Continental truck and bus tires in Europe, Middle East, and Africa.
