14 | Overdrive | July 2019 During its Movin' On Summit last month in Montreal, Michelin introduced a nonpneumatic tire, the Uptis, which it co-developed with General Motors. The Uptis tire is the second concept tire to debut at the annual summit and follows the 2017 unveiling of the company's Vision tire. Like the Vision, Uptis meets Michelin's four primary attributes of innovation in that it is airless, 3D-printed, fully sustainable and connected via sensors. The Uptis looks more like a production-ready tire than the Vision. Michelin expects the Uptis to enter production by 2024, said Eric Vinesse, executive vice president of research and develop- ment. Michelin and GM expect to test the Uptis prototype, beginning with passenger cars such as the Chevrolet Bolt EV. Vinesse said Uptis features improvements in architecture and com- posite materials that enable the tire to bear the car's weight at road speeds. Its structure is enabled by new high-technology materials, re-engineered rubber components and a new-generation resin for reinforcement that Vinesse said took more than 10 years to develop. Vinesse said these innovations can save about 200 million tires worldwide from being scrapped prematurely as a result of punc- tures, damage from road hazards or improper air pressure that causes uneven wear. — Jason Cannon Michelin debuts new high-tech airless tire The National Highway Traffic Safety Administration estimates that when 2018 driving fatality numbers are finalized this year, fatalities in acci- dents involving at least one large truck will see a 3% increase over 2017. A preliminary report from NHTSA released last month indi- cates there was a 1% decrease in traf- fic fatalities across the United States in 2018, even with a 0.4% (12.2 bil- lion miles) increase in vehicle miles traveled. If NHTSA's estimates hold true, 2018 will be the second consec- utive year to see a decrease in traffic fatalities following two years of large increases in 2015 and 2016. While NHTSA's preliminary data shows truck-involved fatalities increased by 3%, it doesn't detail the number of those fatalities. Last year's data showed a 9% increase in truck- involved fatalities from 2016 to 2017. The agency's preliminary data esti- mates that 36,750 people were killed in traffic crashes in 2018. Pedestrian and pedalcyclist fatalities increased by 4% and 10%, respectively. According to this year's data, most regions across the country saw a decrease in traffic fatalities, with the largest percentage decrease being seen in the upper Midwest, which saw a 5% year-over-year decrease. New England saw the largest year- over-year increase, at 4%. — Matt Cole Estimated truck-involved fatalities higher in 2018 Michelin expects to begin production of the airless Uptis by 2024. MORE THAN 4,000 Kenworth and Peterbilt trucks are included in a recall prompted by a potential mirror issue that was announced by the National Highway Traffic Safety Administration. The recall from Paccar includes approximately 4,051 model year 2020 trucks: Peterbilt models 520 and 579 and Kenworth models T680, T880 and W990. RJR TRANSPORTATION, a California-based 60-truck fleet, was granted a waiver to allow its drivers to increase their 100 air-mile short-haul radius to 150 air miles. Most of its trucks operate within 100 air miles of its head- quarters, meeting an exemption standard for electronic logging devices. Because five drivers who maintain logs occasionally exceed 100 air miles, the company would have to deploy ELDs fleetwide to allow its drivers to switch trucks. DAIMLER TRUCKS NORTH AMERICA recalled about 740 trucks of various makes and models due to the vehicles potentially having insufficient service brake air reservoir capacity.
