Michelin Latitude Sport 3 – 255/45R20 (101W) AO GRNX is a high-performance summer tire specifically developed for premium SUVs and crossovers, such as the Porsche Macan and Audi models, as it is marked with Audi Original Equipment (AO). Featuring Michelin’s Green X® technology, it promotes fuel efficiency and environmental friendliness. The tire’s advanced asymmetric tread design offers an increased void ratio, which enhances wet traction. Variable thickness sipes reduce tread block movement, improving rolling resistance and contributing to better fuel economy. Internally, it is constructed with two high-tensile steel belts reinforced by aramid and nylon hybrid filaments to provide high-speed stability and a comfortable ride. Certain sizes, including this one, come equipped with Michelin Acoustic Technology, which incorporates a sound-absorbing foam layer on the inner liner to reduce cabin noise. However, being a summer tire, it is not suitable for use in near-freezing temperatures, snow, or icy conditions.
