Bridgestone Launches New Fuel Saving Bus Tyre

The new flagship tyre in the city bus segment comes with decreased rolling resistance and extended mileage to reduce fuel consumption

Bridgestone launched its new flagship tyre in the city bus segment, the Bridgestone U-AP 002. According to the tyre maker, the U-AP 002 is successor to the U-AP 001 and has been designed to lower fuel consumption and exhaust emissions in congested urban areas thanks to decreased rolling resistance. Plus, by increasing tyre life through enhanced durability, the result is a tyre enabling a reduced total cost of ownership.

Bridgestone says, the U-AP 002 comes with a B-grade in rolling resistance, to reduce fuel consumption and exhaust emissions. The new flagship tyre also offers 9 per cent longer tyre life to ensure excellent mileage1; the tyre’s thick sidewall protection and strong casing enable high robustness and multiple tyre lives thanks to retreading. These features combine to result in a long-lasting tyre that reduces total cost of ownership per kilometre.

The new tyre comes with a 200kg higher load capacity – a key electric bus requirement – and is suitable for eight tonne steer axles. As well as CO2 emissions, the Bridgestone U-AP 002 is engineered to decrease urban noise pollution, reducing output by 2dB in PBN from its predecessor. The new flagship tyre also provides safety and peace of mind year-round as it’s fully winter ready, with 3PMSF and M+S markings, said the company in a release.

The tyre’s new closed pattern design and sipe geometry ensure better performance for urban environments: the closed pattern design supports city driving while travelling at a higher torque; the new sipe geometry protects the tyre from side forces during operation. These features combine to give the U-AP 002 high protection against irregular wear, reduced noise levels, lower rolling resistance and prolonged wear life, it further added.

The new flagship tyre was also developed with an improved rubber compound, created with premium materials; the high silica in the cap compounds improves rolling resistance, wear life and wet grip. The Bridgestone U-AP 002 also benefits from new drainage technology, which contains a central water channel to improve drainage and help the tyre attain excellent grip in wet conditions.

Developed in Bridgestone’s European Research and Development Centre in Rome and produced in Europe, the Bridgestone U-AP 002 has been tested in seven countries by Bridgestone’s fleet customers across internal combustion, hybrid and electric powertrains and is available in its master size, 275/70 R22.5, from 1 April 2021, says the tyre maker.

Three further sizes – 245/70 R19.5, 215/75 R17.5 and 315/60 R22.5 – will be available later in the year, with 265/70 R19.5 launching in 2022. The pre-cured tread U-AP 002 master size will follow and be launched in 275/70 R22.5 at the end of 2021, supporting Bridgestone’s ‘Total Tyre Care’ approach.

According to the company, all the U-AP 002 tyres in 22.5-inch variants will be equipped with electronic tyre tagging system RFID. RFID enables tyres to be tracked throughout their entire lifecycle, which brings various benefits, including improving both safety levels and tyre recycling rates.
