How tires got this way?
Hey guys any idea why these tires look this way?
Is this from hard track riding. or driving these summer only tires in the cold?
Michelin Super Sport. These are the front tires..
Thanks for any input..

I would say track. Have you done an event recently?

That’s not track damage. Track related wear shows up as discoloration (blue tinged) from heat generated, or clumpy look from the hot tread picking up existing clag and spent rubber on the track surface.
That look to me like sun damage, from being stored outside under the sun. Over time the rubber hardens and cracks from UV exposure.
This was on my new GS. Car was parked outside for nearly 2 years at the dealership:
The car car sat in the same spot for months and months (I know because I went by a few times to look and the car never moved), and this is the side where it faces the sun for an extended time (east) where by afternoon the car would be under shades. The tires on the opposite side has some cracking but not as bad.
When I bought the car I told them I wasn’t going to drive the car off the lot (for that matter, PAY for it) unless they put brand new tires on it.

here is my tire after a track day...
completely different now that I am home to compare....
so like the Hack said, this is from age/sun, not driving in cold or track time.

When we bought my wifes car the dealer replaced the P-zero's because they were cracking. The car sat on the lot over a very cold winter. The tires looked just like yours.
