Michelin nose and main tires are fully approved by Embraer on the 190 and 195 family of aircraft.
Tires are undergoing approval at Embraer for the 170 and 175 family; − formal approval is expected to be received 2Q 2010.
The main tires employ NZG technology for:− Superior LPT performance thus reducing operational costs.− Lower tire weight leading to operational fuel savings.− More robust design which provides increased FOD resistance.
Main tires are designed to be retreadable − (From 2Q 2009 for ERJ190 - Kansas City)

Weight saving with Michelin radial tires versus bias:• Ship set weight saving on Embraer 190: 54.6 Kg / 120.1 lb [2*(12.0-10.9)+4*(71.8-
58.7)]
• Ship set weight saving on Embraer 170: 26.6 Kg / 58.5 lb [2*(11.4-10.9)+4*(42.4-36.0)]
Mixing Restrictions:• Embraer does not authorise mixing of radial and bias tires on the same bogie.• Radial tires may be fitted as a pair to one bogie, and bias as a pair, to the other.

• ERJ190: the radial main tire has twicetwice the LPT performance of the bias. This leads to fewer wheel changes and much reduced maintenance costs.
• Actual performance data, over 12 months in 2008, from a major US regional operator supports the above estimates on ERJ190.
Main: 655655 average LPT
Nose: 277 average LPT
