Summer cracking below 20*
Has anyone ever experienced their Summer Performance tire having their tread crack in twenty and below Fahrenheit temps.
Anyone have Michelin Pilot Super Sport tires crack in cold weather? |

I can tell you this is a problem specifically for the N Rated Porsche tires as I've had to claim MANY sets for warranty purposes. As per Pirelli and Michelin (only brands I see this with) it does not effect the performance or safety of the tire and is merely cosmetic.

Never gets to 20 where I live so I'll never know.

You mean you're running them at those temps or just sitting in the garage? I'm no chemical engineer but I know the compounds used are not meant to perform well at low temps, get hard and brittle, etc.
