1 New Technologies - Tires - Paul Johnston Michelin North America Greenville, SC

2 New Technology - Tires What is accelerating the adoption of New Technologies? –Fuel Costs –Freight Efficiencies –Environmental Concerns –Regulatory & Legislative Landscape

3 New Generation Wide Base Single (NGWBS)

4 It is tire replacing duals

5 Moving from 18 10 Wheels on the Ground 18 wheels 10 wheels

6 Traditional “Super Single” 425/65R22.5 New Generation Wide Base Single 445/50R22.5 Super Single vs NGWBS

7 How do the footprints compare? NGWBS 445/50R22.5 Duals 275/80R22.5 Traditional “Super Single” 445/65R22.5

8 What Benefits does the NGWBS provide? Cost Reduction –Improved fuel efficiency, approximately 4% - 10% Freight Efficiencies –Greater payload, savings of 175 – 200 lbs / axle –Fewer trucks on the road –Ease of maintenance Reduced Carbon Footprint –Better fuel mileage (lower Rolling Resistance)….. …….fewer Greenhouse Gas emissions …resulting in a more competitive Transport Industry!

9 Fuel Savings

10 Where Does Your Fuel Go? Aerodynamic Drag Mechanical Losses Rolling Resistance At 60 mph, aerodynamic drag consumes approximately 40% of the fuel. Mechanical losses consume approximately 25% of the fuel. Rolling resistance accounts for approximately 35% of the fuel consumed.

11 What does a Department of Energy (DOE) Study show? Improvements in Fuel Economy with Various Combinations of Tires on Class 8 Tractor Trailers Benefit vs duals only Benefit using only wide singles Fact #537: September 22, 2008 NGWBS on Class 8 Tractor Trailers Improves Fuel Economy by 9.2% Oak Ridge Lab; 750,000 real-world miles; 1 year test 9.2% => approx $1.1m fuel savings for a Fleet of 175 power units ($6,539 per tractor)

12 Freight Efficiencies

13 How does the NGWBS Tire Allow for Greater Payload?

14 How the NGWBS Tire Saves 175+ lbs per Axle DUALSNGWBS (Aluminum Wheels)(Aluminum Wheels)Tire/Wheel x Qty.

15 Environmental Impact

16 How the New Generation Wide Base Tire Saves Oil Dual Tire 12 Gal Dual Tire 12 Gal Wide Base 15 Gal

17 SmartWay EPA Bulletin: Single Wide Tires

18 MICHELIN ® X One ® Tires Since its introduction in 2000, MICHELIN ® X One ® tires have helped save –63 million gallons of fuel, and –639,000 metric tons of CO 2 emissions –the equivalent of removing 127,800 cars from the road

19 Regulatory & Legislative Environment

20 INDUSTRY NEWS Legislative Changes  Energy Independence & Security Act 2007  CARB impact  Clean Air Act  2010 Presidential directive for Fuel Efficiency & GHG standards

21 EPA / NHTSA Joint NPRM GHG Emissions & FE Standards Medium and Heavy-Duty Engines and Vehicles EPA GHG emissions standards –Implementation  MY 2014 NHTSA fuel efficiency standards –Implementation MY 2014  voluntary compliance with credits available. MY 2016  mandatory compliance to “average“. Metrics Vehicle ClassCO 2 Fuel Efficiency Class 2b Pickups, vans grams/milegallons/100-mile Class 3 – 8 Work, vocational, tractors grams/ton-milegallons/1,000 ton-mile

22 Each standard will be assigned a CO2 emission target Aerodynamic features with lower Cd 7 gCO 2 /ton-mile Low RR tires (lower drive and steer Crr) 5 gCO 2 /ton-mile Idle reduction timer (shuts down after 5 min) 5 gCO 2 /ton-mile Reduced weight (wide single tires) 3 gCO 2 /ton-mile New 2014 standard target = 80 gCO 2 /ton-mile EXAMPLE: Raised Roof Sleeper w/Trailer Note: Default engine to be used; Engine per OEM measured separately Figures are for illustration only source: Volvo Mack 2010 ATA Panel 2010 Baseline = 100 gCO2/ton-mile Below are the ONLY credit options to meet Standards : NGWBS impact

23 What does Industry want? …. uniformity & harmonization….

24 Industry Standards & Government Regulations U.S. States - NGWBS LCV Oversize/Overweight Permitted Operations Only (GVW > 36,364 kg / 80,000 lbs) US permit-issued operation (O/S, O/W, LCV) –“... each axle (non-steering) must have 4 tires...” South Dakota, New York, –“... two tires at each end of each axle...” Kansas, –“... minimum axle width...” California –Limitation of 500 lpi (pounds per inch tire width) Montana, Nevada, S.Dakota, Washington, Utah (500 lbs LCV) (Modified 6/13/11 – SL)

25 Industry Standards & Government Regulations U.S. States - NGWBS LCV Oversize/Overweight Permitted Operations Only (GVW > 36,364 kg / 80,000 lbs) DC Alaska Hawaii Forms of State restrictions CA - specific minimum axle width TX - 2 axle 35’ – 45’ bus LA - rear axles of waste disposal trucks (Modified 6/13/11 – SL)

28 Summary: Benefits provided by the NGWBS Cost Reduction Freight Efficiencies Reduced Carbon Footprint new generation wide base single Industry Position: new generation wide base single Net Positive Economic/Environmental Gain when balancing the pro’s v con’s

29 future of tire technology….. Today! …..the New Generation Wide Base Single tire is the future of tire technology….. Today!
