Rolled my 992 out of the garage this morning and headed out the driveway. Not more than 200 feet traveled and I see the TPMS warning saying -32 PSI lost left rear tire. I immediately stop and reverse back to my garage and by the time I get there the tire is hissing like mad and dead flat 30 seconds after I was out of the car. Easy to see the problem, a metal shard in the sidewall. But how? I had just washed the car the night before and know from cleaning the wheels that there was nothing in the tires, they were fine.
The loss was instant after backing out, which means it had to happen inside my garage when I backed out, but how? I have a Race Deck floor that I keep clean all the time, the garage is squared away? Half the day I had this problem working in my mind and then came to the conclusion that it was a random metal shard from one of my garage projects done who knows when that was probably laying around under a toolbox or shelf unit somewhere. I blew pollen out of the garage floor recently and must have disturbed this piece of metal shard and blow it around where it landed at the base of the tire, pretty much invisible against the black Race Deck floor. When I backed out, the shard penetrated the tire. So it was the leaf blower that did it, I'm pretty sure.
Tire Rack Replacement $ 416 with tax, my mobile tire guy will be here Thursday morning to pop it on for $ 75, and then I'll be good to roll again. What a shame though, just 860 miles on the tire and it's done.
That's a bummer. Sorry for your annoyance.
At least, it's just one. With only 860 miles, you won't have to do any shaving, because the circumference should be pretty much the same.
I once lost 4 Michelin Pilot Sport tires at once, with about 1200 miles on them -- the last set of tires I ever bought without road hazard protection.
Yes, bummer. I was at the range today and noticed a gouge in my 8 iron. Strange as I don't remember hitting anything. New clubs. Should this be a separate thread?
Not unusual at all. First time at golf? It may take quite a few swings before you actually hit the ball.
Happened to me twice in one week with my 991 a few years ago. I didn’t have the tire insurance then but I bought it for this new one, so you know I’ll never have a problem with my tires on the 992...:-)
That really sucks, but better it happened at home than on a twisty road going fast. When they fix it ask for the shard and try to figure out where it came from.
I made a "How to Fix Your Flat Tire" presentation. I cut one of our tires apart to make a more portable demonstration piece. (see the attached)
As you can see, the sidewalls on these tires are extremely thin. This goes a long way towards explaining the apparent sidewall fragility of our tires.
FWIW, you can not safely patch the sidewall of any tire.

I, too, have had a piece of metal in the sidewall on a virtually-new Michelin on a Porsche. I picked mine up while getting off the freeway, however, and luckily only needed to drive a mile to Discount on the flat tire to get it fixed.
... and this is why you buy the wheel and tire plan for these high performance cars. No questions asked, tire (or wheel if you damage that) replaced and you're on your way.

True that you can’t safely patch a sidewall, but I’ve plugged them as a temporary fix just to get me home or to the tire shop. I carry a plug kit and compressor in all my cars. I once plugged a hole in my sidewall on the road about 50 miles from home. I activated the tire pressure indicator on my dash and carefully drove to the dealer with one eye on the pressure. I didn’t lose a pound. Perhaps that isn’t a recommended practice, but I did it for science. 😏

My exact experience X 2 inside of a month, PIA and expensive.
860 miles? Now you have to buy 4 new tires or run the risk of having varying levels of tread/traction.
OCD costs money.
That OCD needs treatment . That cut-up tire was mine after a drill bit got in at 1000 miles - I donated it for "science." I replaced it with a new one (only the damaged tire) and the car drives just fine. The differential treadwear after 1000 miles is trivial.
