WHEEL END CHALLENGES An APD cruiser is parked next to a set of double wheels that police said were separated from a semitrailer truck and struck a pedestrian on Interstate 40 near Coors on Monday. The pedestrian died. (Greg Sorber/Journal) A set of dual tires separated from the trailer of a semi truck and struck and killed a pedestrian on Interstate 40 near Albuquerque, N.M., according to local media. Police said a mechanical failure caused the set of dual tires, along with the wheels, to separate from the trailer while the truck was traveling westbound. The pedestrian was traveling east on the shoulder and was struck by the tires. Police are still investigating the accident. ALBUQUERQUE NEWS January 2016 6
DO YOU SEE THE MESSAGES? Worn tyres are messengers They accurately record the maintenance & operational philosophies 7
INDICATIONS TYRES PROVIDE • Overload / under inflation destroys tyres • Dragging brakes; increase tyre pressures • Bearings; 5 psi pressure difference between duals reduces bearing life by 10% (BPW) • Axle camber is identified by tyre pressures • Alignment; axles & trailers 8

WHEEL END CHALLENGES The top breakdown reason for transport businesses operating in New South Wales is the battery, a new study by roadside assistance specialist NRMA Business Motoring has found. According to the study, conducted in collaboration with Prime Mover magazine, transmission problems also rank high as a breakdown cause, while substantial engine work is much less common. “Wheel and tyre issues are a key breakdown cause, followed by electrical faults and defects of the diesel fuel system,” said Matthew Beattie, What’s your Head of NRMA Business Motoring. downtime from tyres? 10

TYRE PERFORMANCE INFO The S.2 Tire and Wheel Study Group of the American Trucking Associations’ Technology and Maintenance Council (TMC) surveyed 435 fleets 21 respondents, 50% line haul operations, 41% regional 29% pickup & delivery. The average number of trailers in the responding fleets was 2,093, indicating some large fleets responded Average tyre mileage to take-off by position: # Steer position: 117,000 miles => 188,000 kms Drive position: 236,000 miles => 379,000 kms Trailer position: 123,000 miles = > 198,000 kms # http://www.moderntiredealer.com/article/312350/how ‐ do ‐ fleets ‐ manage ‐ tires

TYRE PRESSURE MONITORING SYSTEMS (TPMS) mandated in USA from 2008 European Union 2012 Korea & Taiwan 2013 China 2014 TPMS is recognised as a legitimate road safety tool but it is also a great tool for tyre management Real time tyre pressures will increase vehicle safety & economic returns for a commercial fleet. 17
