I'm sure others have posted on this, but I just discovered today that my tires are no longer available. In Dec 09 I replaced all 4 tires with Michelen Hydroedge Green X 185/65 R15. I got a bad puncture today and need to replace the tire. I'm now stuck in that, I can't replace with like. I can't move up a size without changing at least two tires. Even if I went to the A/S they are on backorder to January. They have done this to me in the past with my minivan tires changing the Primacy line after I had bought them. So I'm done with them, I think I'll order some Pirelli all-seasons to get me to the Spring.
I am done with them long time ago after they over priced the tires and them tempt people with $70 discount coupons. No doubt they are very good tires.
May I suggest you look at the Continental Contiprocontact with Ecoplus? Luscious Garage now uses them as well. Until the Yokohama Bluearth tires are released the Contiprocontact is my favorite choice.
