I had a right rear flat today. Don't know why yet.
But when you get a flat on a performance car, do you need to replace both rear tires? Only have 5260 miles on the car.

I looked at the tire when I got it off. Couldn't see any punctures, but two spots on the inside sidewall were worn through.

Anyone know of tire interference problems as it is going flat?

 

Example... ( As you gave no history or reason..For your rear tire..)

I had a rear tire with a slow leak.. the tire presure droped to 22 to 25 Lb's..

The tire was broken down to repair the slow leak..
The inner side wall and the tread had rubbed a V grove, nearly to the out side wall.. Glad I never took the car to speed on that tire..

Low pressure and high camber can destroy a tire from the inside.
