At long last, I've found my tire: an ultra high performance all-season tire that optimizes the performance of Audi's Quattro AWD on trips to the mountains, without numbing the car's handling and steering response on the dry roads that dominate daily driving here in LA. I've only had the Michelins a couple weeks, but immediately took them on a 1,000 mile road trip from Los Angeles to Lake Tahoe where we encountered a wide variety of weather and roads: highways, 2-lanes, dry, wet, snowy, and what the local papers called the storm-of-the-decade. The tires performed terrifically. Prior to these, I had tried a pair of Continental ExtremeContact DWS06, but hated how they severely neutered the vehicle's sporty qualities; I quickly went back to the factory-spec'd Bridgestone Potenza Max Performance Summer tires and unwisely used them (with fingers crossed) every time I drove up to Mammoth to ski. Oh, and one more surprising bonus was how smooth and quiet the Michelins are -- they truly transformed my car's ride. They may be stiffer and less comfortable than other all-season tires, but if you're coming from a summer tire, they should feel like butter. Highly recommended.
