We've put 50k miles on these tires and are due for a new set. I'm guessing we could've put up to 5 or potentially 10k more, but I wasn't that great at rotating them, so 2 of the tires are at the wear bar and my wife just recently trashed one of the 2 good ones (not yet at the wear bar) driving on a flat. There sure seems to be a lot of nails in the neighborhoods she drives through.
Anyway, I've been very happy with these tires and will most likely buy another set unless I can find and convince myself to buy a value set of tires with great ratings & reviews. Paying $800 total (installed/out the door cost) just seems like a lot of money these days. It'll be tough to go another route though because these tires do instill confidence in wet & light snow weather. And our (actually her) 2005 Acura TL drives well with them.
