MY MICHELINS

The experience of my first two installed Michelin Pilot AS 4's on my vehicle prompted the second purchase of the other two to complete the set. I replaced my tires with these on my vehicle because of the Michelin tradition for tires along with the performance and quietness they bring.

Best all-season tire for performance cars

Very durable tire with great handling and responsiveness in all weather. I have put these tires on multiple vehicles that I have owned (Toyota Camry, BMW X6, Audi A6, Lexus GS300) over the years and they've exceeded the 45K warranty every time. They have excellent traction especially is wet weather conditions greatly minimizing hydroplaning instances.

Fantastic all-around tire

Excellent tire. The compound is sticky and aggressive while still offering good traction in cold weather. The tires appear to be well made with a very still XL-rated sidewall. Handling is extremely precise and predictable with perfectly controlled behavior when approaching the limits of cornering grip. The tires are very comfortable and pretty quiet for a performance A/S tire. While I cannot comment on tread life or highway stability just yet, no doubt those will meet expectations as well.
