Contents Market trends Regulatory developments Specifying the right tyres on new vehicles Improving winter mobility in the UK Tyre Management Q & A
Market trends Truck: 295/80 R22.5 giving ground to 315/70 R22.5 Replacement: 295/80 has lost 6 points to 31% since 2010 OE: 315/70 R22.5 now represents 77%. Change driven by Euro VI Trailer - replacement tyre market: 385/65 remains pre-eminent, with 55% share 215/75 R17.5 has gained 7 points to 17% since 2010
Regulatory developments Tyre technical regulations are defined by UNECE in Geneva so limited Brexit impact is expected Current: Roll-out of UNECE reg 117 raising minimum performance levels of truck tyres offered on the market from May 2019 Implementation of VECTO fuel efficiency calculator Future (post 2020): Expect continuing trend towards lower noise & rolling resistance but not before 2023 Strong case for TPMS but need a robust solution to the interoperability issue
VECTO: Vehicle Energy Consumption calculation TOol Reliable independent fuel consumption forecasts based on the vehicle option specification and intended application No scope for test manipulation Reliable comparative data Better decision-making Will highlight the importance of matching the tyre to the vehicle application Legislative proposals are currently under discussion Target implementation date of 2018 will probably slip VECTO will provide truck buyers with reliable independent fuel consumption forecasts based on the vehicle option specification and intended application Urban, regional, long haul, construction, municipal utility Data from VECTO will highlight the importance of matching the tyre to the vehicle application – accepting the vehicle manufacturer’s default tyre fitment could cost you dear
Improving winter mobility in the UK Getting the most out of “ordinary” tyres Tread depth: at least 3 – 5 mm Inflation: optimised for the load carried Brake balance: not too much on the tractor Seek tailored expert advice for best performance Extra performance from tyres with the Alpine symbol Principally on the drive axle In extreme conditions with ice and snow
Tyre Management Don’t improvise – have a robust management system to ensure: Tyres in service are appropriate to the vehicle and operating conditions Tyres are regularly and closely examined for damage and wear Mechanisms are in in place to address any identified issues Staff are properly trained and empowered – tyre technicians, vehicle fitters, drivers
Legal minimum tread depth
Irregular tread wear Tyres often wear more on one shoulder than the other Causes can be road-related or vehicle-related Turning the tyre on the rim can extend tyre life and provide cost savings A tyre should be turned on the rim early enough to equalise the wear A difference greater than 3mm from one shoulder to the other should instigate a turn on rim
Wheel alignment Poor alignment will affect: Tyre wear Vehicle handling Fuel economy
Correct inflation Inflation influences Performance Safety Tyre life Ride and handling An error in pressure of 20% will reduce tyre life by up to 25% One tyre underinflated by 25% may contribute to an increase in fuel consumption of 3% Fix the cause of pressure loss – don’t just re-inflate
Training Having competent staff is a statutory requirement Drivers Vehicle maintenance staff Tyre technicians – in-house or external Training, accreditation and relevant experience Tyre management isn’t “obvious” – investment in training will pay back handsomely Courses are available from technical colleges, tyre manufacturers and others
