I just discovered that my right rear tire has gone flat, mostly due to a piece of an exploded tire that I ran over on the freeway. I was wondering should I just replace that one tire or should I replace all four of the Potenzas? My current tires have about 5400 miles with most of those miles accumulating on the freeway. I rarely push my car to its potential, so the car is more of a grocery getter than anything. Thanks for any help.

It depends how worn your rears are. But you don't need to replace all four, just replace both rears if you have to.

First I'd find out why the tire was flat. If it's a puncture in the tread, just have it patched.

As for buyingg new OE tires--good luck! there aren't any, and likely won't be any available for at least 6 weeks.
