Michelin Proprietary IBERIA “Near Zero Growth” Radial Tyres Application on A October 2002

Michelin Proprietary “NZG” TECHNOLOGY What is NZG ?? Our R&D Efforts have developed a new Reinforcing Material :  Higher Modulus than Nylon (Growth limited to less than 3%)  Modulus stable with temperature (Maintains geometry at high temperature)

Michelin Proprietary Elongation (%) Force NEW CORD NYLON CORD Working Point when Tyre Inflated at nominal pressure “NZG” Casing and Belt Plies are made of high tensile cords “NZG” TECHNOLOGY

Michelin Proprietary “NZG” TECHNOLOGY Bias Radial nylon Radial NZG Bias/ Radial/ NZG Radial Construction

Michelin Proprietary “NZG” TECHNOLOGY Inflation + 8 % diameter Centrifugal force + 4% diameter Centrifugal force + 2% diameter Inflation + 6 % diameter Centrifugal force + 1 % diameter Inflation + 2 % diameter Tyre growing : Bias / Radial/ NZG Radial

Michelin Proprietary “NZG” TECHNOLOGY Non inflated tyre : Nylon vs NZG Comparison For a given inflated diameter, because NZG grows less, its non-inflated diameter is larger

Michelin Proprietary Tyre weight can be adjusted to optimize performance. NZG tyre is up to 15 % lighter than equivalent Michelin radial nylon tyre. While often keeping a deep skid for optimum landings per tread. Lower moment of inertia produces less wear at touch down. “NZG” TECHNOLOGY

Michelin Proprietary “NZG” TECHNOLOGY NZG design features  NZG structure grows less than nylon. (non inflated tyre size 5 cm larger than equivalent nylon tyre )  Squared and balanced footprint  Ability to resist FOD / tyre survivability.

Michelin Proprietary. NZG structure  Reduced Elongation. Better resistance to abrasion for optimum landings per tread and reduced maintenance. Better resistance to tear and cuts for a reduction of early removals and increased average landings per tread. Better tread and sidewall resistance to ozone attack & aging. “NZG” TECHNOLOGY
