2 What is accelerating the adoption of New Technologies? New Technology - TiresWhat is accelerating the adoption of New Technologies?Fuel CostsFreight EfficienciesEnvironmental ConcernsRegulatory & Legislative LandscapeFuel has increased ____ fold over 2010For every $1 spent on tires, $15 spent on fuelDo more with less, haul more freight with fewer trucks, drivers, miles driven; increased adoption of telematics, routing s/wPressures on the industry to meet more stringent yet beneficial regulations ranging from CSA, to fuel mileage, to emissions, to braking distances to EOBRs/HOS
6 Super Single vs NGWBS New Generation Traditional Wide Base Single They say a picture is worth a thousand words– On the left the 425/65R22.5…………..speed rated 65 mph; on-off road compounding, high RR– On the right the 445/50R22.5…………speed rated 75 mph; multi application (LH, Reg, On-Off, Urban), lower RRIf the old wide base was a work boot; the new X One® tire is more like a sneaker.New GenerationWide Base Single445/50R22.5Traditional“Super Single”425/65R22.5

8 What Benefits does the NGWBS provide? Cost ReductionImproved fuel efficiency, approximately 4% - 10%Freight EfficienciesGreater payload, savings of 175 – 200 lbs / axleFewer trucks on the roadEase of maintenanceReduced Carbon FootprintBetter fuel mileage (lower Rolling Resistance)…..…….fewer Greenhouse Gas emissions…resulting in a more competitive Transport Industry!
10 Where Does Your Fuel Go? Aerodynamic Drag Mechanical Losses At 60 mph, aerodynamic drag consumes approximately 40% of the fuel.Aerodynamic DragMechanical losses consume approximately 25% of the fuel.Mechanical LossesRolling resistance accounts for approximately 35% of the fuel consumed.Rolling ResistanceAerodynamic drag is the natural resistance of the air being pushed by the truck.Aerodynamic drag is a function of the vehicle frontal square footage, the aerodynamic shape of its leading edge and the square of its speed.At 60 mph, aerodynamic drag consumes approximately 40% of the fuel.Mechanical losses are related to the engine’s ability to convert part of the fuel energy, the friction associated with the various drive train components and the various accessories being run.Mechanical losses consume approximately 25% of the fuel.Rolling resistance is related to the heat generated by the tire’s sidewalls and tread design as they flex and squirm.This natural characteristic of rubber to generate heat while flexing is called hysteresis.Rolling resistance accounts for approximately 35% of the fuel consumed.Hysteresis is the natural characteristic of rubber to release only part of the energy that it consumes to deform.The best way to show this is with a rubber band. If you test the temperature of a rubber band by putting up against your lip and then stretch it couple of times, and then check the temperature again, you will notice that it got warm. It retained energy.The tread design of a tire does the same thing as it compresses and releases.
11 What does a Department of Energy (DOE) Study show? Improvements in Fuel Economy with Various Combinations of Tires on Class 8 Tractor TrailersBenefit using onlywide singles9.2% => approx $1.1m fuel savings for a Fleet of 175 power units($6,539 per tractor)Benefit vsduals onlyThe NGWBS tire has only two sidewalls flexing instead of four.The NGWBS tire uses advanced technology compounds.The NGWBS tire can reduce the truck rolling resistance by more than 12% compared to our most fuel efficient dual.Fact #537: September 22, 2008NGWBS on Class 8 Tractor Trailers Improves Fuel Economy by 9.2%Oak Ridge Lab; 750,000 real-world miles; 1 year test

20 INDUSTRY NEWS Legislative Changes Energy Independence & Security Act 2007CARB impactClean Air Act2010 Presidential directive for Fuel Efficiency & GHG standardsGovernment Regulations & EnvironmentThe Environmental Protection Agency and DOT’s National Highway Traffic Safety Administration (NHTSA) have published their formal fuel efficiency and emission standards for heavy duty trucks on the Federal Register.Comments must be received before or on January 31, 2011.The EPA’s greenhouse gas emissions under the Clean Air Act begin in model year 2014.The NHTSA’s fuel consumption standards under the Energy Independence and Security Act of 2007 would be voluntary for model years 2014 and 2105 and become mandatory in model year 2016 for most regulatory categories.Comments must be identified by Docket ID No. NHTSA–2010–0079 and/or EPA–HQ–OAR–2010–0162, by one of the following methods:• Follow the on-line instructions for submitting comments.•• Fax: NHTSA: (202) 493–2251; EPA:(202) 566–9744.• Mail: NHTSA: Docket Management Facility, M–30, U.S. Department of Transportation, West Building, Ground Floor, Rm.

This accounts for what type of work the truck is doing and not just engine fuel efficiency. Improvements to be met through Engines, Tires, Aerodynamics and Idling , saves 500 million barrels of oil and 250 millionmetric tons of GHG emissions.NHTSA = mpg; EPA = emissionsPayback 2-4 years depending on usage. Vocational and OTR power units but not trailers at this time.

26 What About Effect on the Roads? 100200300400500600700800900100013579Tread No.Contact Pressure (kPa)X One TireDual Tire1Dual Tire2This slide illustrates the ground contact pressure exerted by an X One versus dual LP22.5. Note that the contact pressure at the center is essentially equal and that it is in fact much more equally distributed across the X Ones when compared with duals. The image does not suggest pavement rutting from the X ones as does the duals.The lower pressure in the shoulder area of the dual tires equates to a loss of grip at the tread edges (shoulders) relative to the X One. The more balanced distribution of the X One translates into traction and handling improvements as a function of ground contactThe literature on pavement damage is exhaustive in scope and very often contradictory in its findings, driven largely by inconsistencies in methodologies and data collection. Most of the existing data comparing wide base singles to duals refers to the older traditional wide base or “super single” tires commonly found on the front axles of vocational vehicles in the US. Study on the new generation of wide base singles is relatively new and very limited.Source: Dr. Al-Qadi / VaTech Transportation Institute
27 Regulatory Environment - Pavement Tire Contact StresseskPa signifies kilopascals, i.e. thousands of pascals.1 kPa = 1000 PaPascals are the unit of pressure (atmospheric pressure for instance) equivalent to one newton per square meter.Anytime you see a k in the context of metric it means 10^3 or Pa = pascals or N / m^2, (force / area), a unit of stress or pressure (they mean the same thing, stress is used when referring to solids, pressure is used when referring to fluids). So 1 kPa = 1000 Pa = 1000 n / m^2Read more:Actual Tire ImprintsContact Stress between the Tire and Pavement SurfaceMeasurements indicate comparable levelsof contact stresses between NGWBS and duals.Slide to be used only with written permission of Michelin Americas Research CompanySource: Florida DOT
