- New siping technology for improved grip and traction performance over entire lifetime to ensure safety for passengers
- Comfort, grip and curve stability on dry and wet roads
- Robustness and stiffness to prevent kerb impact damage at Drive axle tire
Hanover, January 8, 2020. Continental, the technology company and manufacturer of premium tires, has launched a new tire line for intercity buses, named Conti CoachRegio. The new tire line 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 tire as well as a dedicated drive axle tire. 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. The new tire is available as Conti CoachRegio HA3 295/80 R 22.5 for all axles and as Conti CoachRegio HD3 for the drive axle. The latter will also be available from Q4 2020 as ContiRe CoachRegio HD3, manufactured using Continental’s hot retreading solution, which provides multiple service lives thanks to durable and robust casing.
Due to its "Three-Peak Mountain Snowflake" marking (3PMSF), the Conti CoachRegio drives smoothly under all weather conditions in all seasons, whereas its durable and robust casing delivers a load capability of LI 154/149, currently the highest available for the drive axle in the coach and intercity segment. Regarding EU Label values, both tires are rated “C” for fuel efficiency and “B” for wet grip, with a rolling noise of 71 dB for the HA3 and 73 dB for HD3 (both with one soundwave).
“With this new tire line, we overcame the technological challenge of developing a tire 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 tires that save fuel, last longer and offer better handling as well as comfort without compromising on the most important requirement–safety” said Lutz Stäbner, Head of Product Management for Continental truck and bus tires 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, functionalized 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.
