Loved the ones i put on my old Sonata, just forget what they were(p7 cintaturo comes to mind..), I know the car had ~80k on the time, and they had an 60-80k mi tread life. realistically the guy who bought they car should still have them on unless he had a puncture.
put set of P4 four seasons on my neon last fall. and so far they've handled everything mother nature has thrown at me. (one of the reviews on discount tire's site for them, from a guy in MI, who put a set on his Neon,said they handled the MI winter like they were on rails. he never felt the need to swap out for winter tires.)
My folks just replaced the OE P6 Four Seasons on mom's '09 Taurus, with another set of the same tires. new tires have almost no noise, the old set (about 5-10k beyond the tread life warranty) had a good bit of road noise, and did a slight hydroplane in monsoon downpour conditions, but never left the road way.
