Picked up a screw in my left rear this weekend. Can't be plugged because the puncture is right where the tread and sidewall meet.

These are PZeros with about 5k miles of tread wear.

Think I can get away with just replacing one tire here?

Possibly. I'd suggest measure the current tread depth and compare to new. most tires for these cars are about 10/32. If your good tire has say 8/32, should be ok to replace just the punctured tire.

Thanks for the input.

What's the danger if the difference in circumference is "too great"? Won't the rear diff account for this? Or will the traction control and ABS be all jacked up?

I wouldn't expect a few /32nds difference in diameter to have an effect on ABS/PSM/TC. The bigger concern I would have is difference in grip mainly in wet conditions. Still PSM should help. I had a similar situation with a set of sport cup 2s. Had 2 track days and a few hundred road miles and picked up a screw. I replaced the punctured tire and had no problems.

Thanks for the background.

My remaining tire is at 7/32s, and the PZeros come with 10/32. Decided to have TireRack shave the new one to 7/32. Was only $30 to have them do it, and will avoid the cost of another tire or having to worry about any issues. Going to have the local dealership mount and balance it. ($60) Realize that's a little more than average, but I don't want PepBoys marking up my wheel.

Thanks again.

That's what I wanted to suggest : tire rack and shaving. Looks like you don't need this forum at all :)

I had that done many years ago. It worked.

In a matter of a couple of months I ended up with three screws in three different tires on my RS5 with PZeros. At the time had about 5k on the tires. Replaced a single tire each time. No issues.
