I had these tires installed on a 2001 ACURA EL in size 195/65R15 as a replacement for Michelin Primacy MXV4. Premier A/S are a replacement for a very proven and exceptional Primacy MXV4 which I installed on my vehicle in April of 2010. Tire installer actually informed me that there is no reason to replace the MXV4 since they had 70% tread remaining; but I informed him that based on age of the tire (7.5 years and 70,000 km) that I wanted them replaced. He could not believe the shape that MXV4's were in. I am a fan of michelin product. In fact, all my tires have been michelin and I just installed DEFENDER LTX M/S on my 2014 Lexus RX350.
