through 10/28, buy four Michelins and get $70 off (pretty standard deal)--but pay with your Costco VISA card and get another $60 off, for a total of $130 off four tires.
The $70 off is generally available from any tire store. The additional $60 off covers Costco's installation and disposal fees. So the net is $151.49 per tire, installed.
I run both AS3+ from Nov to April, and the PS4s for the summer months. As great as the AS3+ tires run, the PS4Ss gives the car that extra kick and the handling feels even better. I just switched over to the AS last week, and even with a Hunter road force balancing and 4 wheel alignment, feels like a downgrade. Its not a significant difference, but the feel is definitely noticeable. Can't wait until April
Well of course the summers will feel better but for those who don't want to mess around with having 2 sets of wheels/tires the AS3+ is one of (if not) the best all arounders out there.
Good to know that they really aren't that far off from the 4S's though!
