New intercity bus tyres from Continental
Continental has introduced a new range of tyres for intercity buses. It says the Conti CoachRegio offers “reliable and safe touring between cities and villages under variable speed conditions, excellent handling and high mileage on hilly and winding regional roads.”
The Conti CoachRegio line includes an all-axle fitment tyre as well as a dedicated drive axle tyre. The new design fulfils the needs of fleet customers who operate in short distance travel and intercity transportation in general as well as those who operate tourism buses, tour buses, school buses or workers shuttles.
Available sizes include the Conti CoachRegio HA3 all-axle fitment and Conti Coach Regio HD3 drive tyre in 295/80 R 22.5. The latter will also be available from the fourth quarter of this year as the ContiRe CoachRegio HD3 mould cure retread.
Both currently available sizes wear the 3PMSF marking and have a ‘C’ label rating for fuel efficiency and a ‘B’ rating for wet grip. The rolling noise values are 71 dB for the HA3 and 73 dB for the HD3 (both one soundwave).
“With this new tyre line, we overcame the technological challenge of developing a tyre using a balanced compound to increase safety and mileage that also features low rolling resistance performance for regional bus applications. With the Conti CoachRegio, we introduce efficient tyres that save fuel, last longer and offer better handling as well as comfort without compromising on the most important requirement–safety,” comments Lutz Stäbner, head of product management for Continental truck and bus tyres in Europe, the Middle East, and Africa.
The balanced compound for traction and mileage provides an innovative combination of rubber polymer and strengthening filler materials. A special, functionalised rubber and a new type of carbon black ensure high mileage with an excellent rolling resistance while at the same time offering superior wet handling and good dry grip.
When it comes to pattern design, the Conti CoachRegio HA3 has full-depth siping technology for good wet and winter performance, with straight grooves in the outer ribs for structural stability as well as zig-zag inner grooves for optimal performance against stone retention. These characteristics result in better cornering stability and quiet rolling, ensuring high comfort for the passengers. The Conti CoachRegio HD3 also features a new tie-bar shoulder design that increases robustness and minimizes damage from kerb impact, while the full-depth 3D sipes enhance water displacement and thus guarantee improved wet performance, traction and safety.
