Well I know they rebalanced them. I'm just not sure if they remembered which tire came from which spot. I'll ask them this fall. Thanks!!

Do they want you to replace both rear tires or just the damaged one?

They didn't recommend one or the other. just asked if i wanted to do one or both. I was hoping they would offer to split the cost and each do one...but no such luck. I told them just to replace the one for right now. I was just so irritated at the time...probably should have just done both. The tires only have 9k on them.

Do you live in a war zone? Looks like a bullet hole.

Well, by 911 standards, that's a ton of miles. And looking closely at your pic in post #1, I see other nearby cuts in the thread, so you probably did run over something.

After you get back up & running again, and the vibration is cleared up, pay very close attention upon aggressive accelerations. If anything wonky is going on, it's because the new tire is 9-10/32's and the old tire is significantly below that differential threshold.

Anyone else first think that looks like a plug ejected itself...?. The threads pulled the way they are, the deformed rubber to one side only -- wouldn't you think this was a plug job that failed? Wobbling feel could have been the plug partially out. I mean, they do fail, right?

No. This is way bigger than could be plugged plus the hole looks almost like it was cut into the tire with a hole punch!. Plug holes are very ragged. Just accept it that you had some bad luck and ran over something like a bolt with a washer under the head just as you left the dealer. Next day it came out. I try to avoid running over anything like you, but last fall I picked up a 3 inch long wheel weight in a rear tire. It made a huge hole but the tire didn't go flat for a couple of hours. Stuff happens.

My thoughts exactly. I once ran over a 1/4" thick by 3" long lag bolt and it made a hole that looked exactly like that. It looked similar to the attached pic.

9k is a TON of miles for the rears. You don’t mention the model (unless I missed something) but if it’s 991.1S then you have PTV (or it could have been optioned on a base) and if you do, in my experience, rear differentials ride very poorly with mismatched tires (or ones with significant treadwear differences). Food for thought...

As suggested you should replace the 9000 mile tire so you have a new set on the rear , buy it from TR and save yourself a few dollars ( have it shipped to one of TR installers and have it road forced balance both of them
