That's one of those statements that sounds good in theory on the internet or tire shop looking to sell tires but I'm not aware of any real world evidence that actually matters enough to provide even a slight measurable increase in risk.

I'd patch this and wouldn't even worry tracking on it. Even if somehow the patch fails which I have yet to see in my life that puncture is likely a 'takes a day+ to lose full pressure in the tire puncture' if it's even through the tire. Long before there is a problem you're going to see a TPMS warning.

Even if by some miracle it deflated instantly I am not sure what you think is going to happen to cause an accident?

If patched properly, there's no problem at all. The "correct" patch is called a "Compound Patch."

Patch. You don’t get points for spending more to accomplish the goal.

Ahhh...the tire patch thread, kind of like an oil thread. Do what makes YOU comfortable.

On my 992, I replace
On my Ford Ranger pickup truck, I repair.

Why? Well the truck is Go-To-Home-Depot and rarely exceeds 60 mph or any heat put into the tires. The 992 is different and I feel more confident in running the car hard with no repairs in the tires.

Some tire makers reduce the speed rating on the tire if repaired. Check on the Tire Rack Website to see if the brand you are running does. Heat is the enemy of all tire repairs, so if you are doing agressive track days, how would you feel if you have a blowout on the repaired tire and crashed because of it? At the end of the day its what you are comfortable with. Me? My $ 160,000 car is not worth getting balled up for $ 400. You may feel differently.

I've had several tires plugged over the years with zero problems. That screw is nowhere near the sidewall.

I would patch. Never had a problem patching in similar scenarios. If you have tire/wheel coverage from the dealer, pretty sure the dealer would patch it also (not replace).

Dealers do not patch, there is too much liability.

One of the reasons to get the whee/tire insurance direct from your Porsche dealership.

By “liability,” do you actually mean “profit?”

This has only a little to do with the OP’s post, but still relevant to the overall discussion.

One consideration on patch versus replacement is whether the tire has suffered any side wall damage, such as driving on a flat or a very low pressure tire. Low air pressure that causes bumps to compress and squash the sidewall into the tire rim is not good.

Our BMW SUV suffered a puncture like the OP’s, but it was a long nail and it came out and we lost all air on our RFT (Run Flat Tire). We drove on the flat carefully to avoid any bumps, maybe 10 miles, slowly. Our tire repair shop inspected the tire, off the rim, carefully, and decided that patching was 100% ok.

Now, many tire shops and tire manufacturers will tell you to replace that tire, and when there is no information (no way to know exactly how I drove), and they cannot afford the time to investigate because a $45 tire repair will simply not pay the bills, then replacement is a more risk-free option.

I've seen this PDF before and if the manufacturers (Goodyear, Pirelli, Michelin) state that you can patch a tire, then I'd be okay with this. Following the rest of the guidelines of course.

In was impressed when I seen them fill the void with the plug and then snip the end of the plug off. And also that that they rebalance each tire during rotation.
