Michelin XAS 180HR15 Tire The XAS is a high quality Michelin radial for many popular European applications requiring a 13-15 inch radial tire and authentic styling. These radial tires feature Michelin's XAS tread pattern and an H speed rating. From its launch in 1965, the Michelin XAS remained the reference tire until the end of the seventies. The first tire with an asymmetrical tread pattern, the inside and outside of Michelin XAS tires work differently to give the car a good balance. Michelin made progress by differentiating the many elements that form the tire, leading to the creation of the XAS. The XAS was constructed taking into account the different kinds of work done by the shoulders, sidewalls and different parts of the crown, depending on whether they are on the inside or outside relative to the car. Just like a person's foot is asymmetrical, the inside and outside of a tire work differently to give the car good balance and sure handling. This major advance allows the XAS tire to give remarkable stability, exceptional road holding ability and exceptional levels of grip in all conditions. The first production tire designed to run at 210km/h, (131mph), its exceptional performance led to the XAS being used in racing in Formula France in 1968, circuit racing, rallies and hill climbs. H Speed Rating H Speed Rated: Up to 130 mph (210 km/h). Often required OE for higher performance trim level classic automobiles. Michelin XAS tire Stability & road holding when cornering.
