tire question

[fatmike]

I blew out a rear tire (ran over a screw, tire lost air on the highway and it tore up). No damage to the car otherwise.

The remaining three tires are pretty new (within 5K-7K miles), so I will keep the remaining tires and just buy a replacement.

Now my questions:
- Should I rotate the other rear?
- Replace the side that flatted and leave the other rear alone?
- On a 986S, does one side of the car get more wear in the rear due to the power train?

Thanks.
