1. The MICHELIN® Radial Tire Advantage

2. Michelin: Inventor of Radial Tires
Michelin developed the first radial tire in 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

4. 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

5. 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

6. Radial Tires Make Machines More Profitable Increased productivity

Increased tire life
Better machine protection
Improved fuel efficiency
Lower Usage Costs

7. Radial Advantages Over a Conventional Bias Tire

8. 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

9. 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.

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.

11. 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.

12. 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%.

13. 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.

14. 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.
