Hanover, April 23, 2015. The German premium tyre manufacturer Continental is expanding its range of passenger tyres with the Conti Urban HA3. The new 19.5-inch tyre has been especially developed for use on medium-sized city buses. The newly developed rubber compound of the Conti Urban HA3 265/70 R19.5 guarantees a particularly long service life even in challenging inner-city stop-start traffic conditions with regular braking and accelerating. In addition, the reinforced sidewalls make the tyre resistant to frequent contact with curb stones which cannot be avoided in public transport operations.
The new Conti Urban HA3 265/70 R19.5 for use in medium-sized city buses guarantees a long service life and optimal driving safety all year round.
The new Conti Urban HA3 265/70 R19.5 guarantees superb handling and excellent grip—ensuring the comfort and safety of passengers. The increased rubber ratio in the new compound strengthens the tyre sidewalls, forming a particularly robust tyre contour together with the steel cord casing. This contour is very forgiving in frequent contact with curb stones at bus stops.
The sipes, which reach the base of the grooves in the tread, also ensure optimal lane tracking over the entire service life of the premium tyre—even in wet conditions.
And it's not only the rubber compound for the tread that has been recently adjusted—the tread design with its high wear volume, "plus volume pattern", is also a new feature. Together they increase the service life of the Conti Urban HA3 by up to 20% when compared with conventional regional tyres.
The Conti HA3 19.5 can be used on all axles. Regrooving indicators to mark regrooving depth are integrated into the tread. Regrooving gives tyres a longer service life with a lower rolling resistance—directly impacting the cost-effectiveness of the fleet. Like all Generation 3 bus tyres, the casing of the Conti Urban HA3 R 265/70 R19.5 can also be retreaded, giving it a second tyre life; a direct competitive advantage for urban bus companies under pressure to reduce costs.
The Conti Urban HA3 265/70 R19.5 is labelled with the M+S symbol, which makes it usable all year-round in many European regions.
