MICHELIN PROPOSES A NEW A319/A320/A321 NLG TYRE 30x8.8R15 - P/N M08202 - NZG Design

30x8.8R15 P/N M08201 / P/N M08202 COMPARISON M08201 M08202 Max tyre weight 22 kg 20 kg Avg tyre weight 21 kg 19.1 kg Number of grooves 4 4 Tread skid depth 0.33 in 0.35 in Tread performance Base 100 120 Retreadability Unchanged M08202 has been designed to be mixable with current M08201

Why NZG ? Provide the Airlines benefit from a reduced maintenance cost due to increased LPT performance. Provide the Airframers benefit from the latest radial tyre technology . Introduce more reliable products for the aircraft industry.

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) Adhesion to rubber maintained up to high temperatures Resist to cyclic fatigue

Working Point when Tyre Inflated at nominal pressure “NZG” TECHNOLOGY 5 10 15 20 Elongation (%) Force NEW CORD NYLON CORD Working Point when Tyre Inflated at nominal pressure “NZG” Casing and Belt Plies are made of much higher modulus cords

“NZG” TECHNOLOGY The reduced elongation provides : Better resistance to abrasion for optimum landings per tread 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 Reduced elongation : Before inflation the NZG tyre is larger than the current tyre. Initial M08201 New M08202 40 mm (1.6 in)

“NZG” TECHNOLOGY But, when inflated and loaded, nylon and NZG tyres have similar outside diameter, and, particularly, identical loaded radius and rolling radius

“NZG” TECHNOLOGY Moreover, tyre footprints are similar New M08202 Initial M08201 New M08202

“NZG” TECHNOLOGY Reduced elongation : The normal initial 12 H stretch period can be reduced to 1 hour (the 24 H pressure check remains)

“NZG” TECHNOLOGY” Our current experience : Fully certified on Concorde Fully certified on Falcon 2000 & 20/50 (MLG) Fully certified on F16 Block 40 Certification in progress on Falcon 900 (MLG) Certification in progress on A340-600 (MLG) Certification in progress Falcon 2000EX (MLG) Certification in progress Cessna Sovereign(MLG) Certification in progress Citation X (MLG) Selected on A380 Selected on Falcon F7X
