I was going to put some all season tires on my 15 4S. I see the Cinturato as a pick on tire rack but when I tried to purchase them from another online store, they sent me an email saying these are not speed rated for my car.

I am confused as tire rack has them as OEM tires. Any opinions on this? Thanks.

 

Yes, you can use them. I used to have them on my previous car. They are good, not great tires in my opinion. They worked just fine.

 

V rated tires are the "fastest" you can get in an "All-Season" tire. (149mph)
You have to go to a summer tire to get the Y rating (186mph).

I have the 20" P7's on my Panamera 4S and have been happy with them.

Regards,

Chuck
