The MICHELIN® Radial Tire Advantage

Michelin: Inventor of Radial Tires Michelin developed the first radial tire in 1946. The radial went on to revolutionize the tire industry! In 1958, Michelin developed the first radial earthmover tire Développée par Michelin en 1946, la technologie radiale a révolutionné l’industrie du pneumatique et a donc rapidement été appliquée à tous les types de pneus Dès 1958, Michelin a, le premier adapté la technique radiale aux pneumatiques pour engins de Génie Civil Aujourd’hui, elle est unanimement reconnue et le pneu radial est indispensable à toute recherche d ’économie et de productivité sur les chantiers Pourquoi depuis 1950 le pneu radial s ’est-il imposé dans la quasi totalité des transports terrestres ? Il est le seul ayant réalisé l ’alliance au plus haut niveau de la charge, de la vitesse et de l ’endurance C ’est la solution économique par excellence

Radial Tires’ Independent Sidewall-Tread Band Design Conventional Bias Tire Design Radial Tire Design The tire is composed of several angled ply layers that all overlap Known as “monoblock” construction The crown is stabilized by a belt layer, comprised of several ply layers The tire is made from one, single radial layer of steel cables Sidewalls and tread bands work independently

Radial Tire Performance Comparison Conventional Bias Tire Radial Tire Impact of tire-ground contact: Severe tire deformation Excess wear on all parts of the tire Excess heat Ground friction Greater motion resistance The sidewalls and tread band work independently. The tread band is not affected by the bending sidewalls. During usage, all bending is transmitted to the tread band due to overlapped angled plies. Surface deformation reduction despite ground contact means: Surface deformation due to ground contact results in: Reduced ground friction Minimal heat Minimal motion resistance

Radial Tires Make Machines More Profitable Increased productivity Higher speed capacity Heavier load transportation Better damage resistance Increased productivity Greater Profitability Maximized operator comfort Better machine handling Robust steel casing Reliable Operations Increased tire life Better machine protection Improved fuel efficiency Lower Usage Costs

Radial Advantages Over a Conventional Bias Tire

Exceptional Load Capacity The load capacity for a conventional bias tire for any given dimension depends on its ply rating. Load Capacity Radial tires can support a higher load capacity than bias tires with the same dimensions. +2.65 metric tons MICHELIN Maximum load per tire (Metric ton = 1.1 tons) Example: 23.5 R25 Michelin Radials can transport up to 5 metric tons (5.5 tons) more per machine if the load is within manufacturers guidelines

Radial Traction Advantage A tire’s traction capability is incredibly important as it directly impacts the load capacity The greater the traction, the more efficient the loader A radial tire’s footprint and Michelin’s unique tread design for loaders limit the tire’s slippage during loading, and increases its overall traction. Charge pneu: 24000 kg Pression pneu: 5.5 b (radial), 4.0 b (bias) More PRODUCTIVITY with Michelin radial tires!

More Material in Every Bucket Measured Results (loading tests in V) MICHELIN® XHA™ 2 Average over 12 cycles Bias + 30% Productivity Gap 0.218 Working time (Hours) 0.243 97.2 / 106.9 Production (Metric Tons / Tons) 83.5 / 91.85 446 / 491 RESULT (Metric Tons per hour / Tons per hour) 344 / 378 Greater work capacity + Greater traction ___________________________ = More material in every bucket With a MICHELIN® radial tire, the average amount of material transported is 30% greater than that of a machine using bias tires1. In a quarry of 100,000 Metric Tons / 110,000 Tons per year, that’s 30,000 Metric Tons / 33,000 Tons more material extracted. (1) Results obtained by the MICHELIN® XHA™ 2 tire (23.5 R 25) compared to conventional tires. The tests were run by CEMA in May 2010.

Proven Fuel Efficiency The less energy wasted by the tire, the greater the machine productivity! With a MICHELIN® radial tire, you save an average of 6% of fuel per ton loaded, and up to 11% in load & carry conditions1. Measured Results (loading tests in V) MICHELIN® XHA™ 2 Average over 12 cycles Bias - 6% of Fuel Consumed (l/t) 3.906 liters / 1.032 gallons Consumption 3.592 liters / .949 gallons 97.2 metric tons / 106.9 tons Production 83.5 metric tons / 91.9 tons 0.0402 liters per m. ton / .0096 gallons per ton RESULT 0.0430 liters per m. ton / .0103 gallons per ton Results: (Average values) Use less fuel to move material for greater PROFITS! (1) Results obtained using a MICHELIN® XHA™ 2 tire (23.5 R 25) compared to conventional tires. Tests run at CEMA in May 2010.

Even Wear for a Maximized Lifespan Even ground contact results in consistent wear on the tread band. Combined with a premium rubber compound, MICHELIN® radial tires have a longer life by 50% to 100%. White marks on the tread band Distortion of bias tires wears away the marks more quickly Michelin Radial Bias Michelin Radial Bias 300 meters After 3290 meters Use one set of radials instead of two sets or more of bias! *Evaluation based on Michelin tests in Almeria : 4-bar axle - 8950kgs Position AVG MICHELIN® XHA™ 2 (23.5 R 25 / 23.5-25 L3 20PR)

A Comfortable Ride The flexibility of a radial tire’s sidewalls significantly increases the driving comfort of the machines. Michelin’s innovative tread design allows for even greater comfort. The MICHELIN® XHA™ 2 tire’s asymmetrical tread design reduces machine vibrations below a physically perceivable level. Sensitivity threshold Vibration Levels Michelin Patented Load weight per tire * Measurement of a tire 20,5-25 at a constant speed Comfortable operators make for productive operations!

Stronger Puncture Resistance Steel Radial casing plies and metal reinforcing belts offer greater resistance to tire damage and punctures in the tread and sidewall than fabric ply bias tires. The higher pressure required for bias tires make them less flexible to absorb impacts meaning they puncture more readily. 23.5 – 25 BIAS Air from the punctured tire stirs up dust. Punctured device. More uptime for more productivity!
