Our Michelin Pilot Sport 4s finally were at about 2/32nds and had to be retired at 32k of usage, so at least they met the warranty lifetime of 30k! My wife is about to start a new job where there may be more 'weather' to deal with so we opted for the Michelin Pilot Sport All Season 4s to replace them with. The tire is excellent, great ride quality and the grip is darn good!
These tires have a 50% upgrade in warranty to 45K so that's a benefit as well for longevity. Only 54K on our 2016 FoST and loving it!
Here's a review from Tire Rack on performance All-Season tires
Overall, we stuck with the 245/40R18 size for a little width gain from the stock 235 size. We've been really pleased with them so far!
