Plugged tire - now patch?
So I picked up a nail a while ago. I didn't know until I noticed the handling felt funny, so I checked my tire pressures and found on tire at 15 psi !
So I popped it off and did the classic plug from the outside with tarred string. Not too hard of a job but I did manage to scratch my fender make sure you use a ratchet extension or a sock around the bottom of your wrench!
I'm wondering if the plug will do, or if I need to now take it in to get a patch from the inside of the tire.
Normally I have good confidence in the plugs, but the car will see some autocross and general hard driving.
Leave the plug or take it in for a professional patch?
(the nail was in the tread, near the inside edge on a rear tire, in the grooves of the tread)

Waiting to hear what others think... but I don't think I would be comfortable with any sort of puncture repair on a high performance tire. Especially near the sidewall.

Some tire makers allow this (though I think a patch is preferred to a plug) and some don't.
For those that do the guideline are: 1) the hole has be in the tread section. Sidewall punctures, forget about it. 2) the hole can't be very big. 1/4" comes to mind. 3) the tire has to be in otherwise good condition. Not at the wear bars to be sure, but another issue is if the tire was driven underinflated for too long.
In the case of being driven too long underinflated the tire can shed some of its rubber inside its carcass/casing and the tire's ability to hold air can be compromised.
Generally, if the tire is dismounted and rubber dust comes out when the tire is removed from the wheel, the tire's toast.
Oh, if you replace one tire if the two tires differ by 15% in size (due to tread wear) Porsche requires the other tire be replaced as well.
Sincerely,
Macster.

Your z rated 155 plus tire just went down to 50mph. Chances are you may not have a problem in daily driving- but why take that chance? I would spring for a new tire right away.

If the tire has been plugged and patched with a mushroom plug, and not near the shoulder - I would drive as normal and just take a look at it once in awhile to make sure that there is no sign of corrosion of the steel tread due to water entry.
Usually with these, if you don't have a problem right away you won't.

The key there Damon is "near the shoulder".
I sure would not be comfortable using a tire plugged near the shoulder at track speeds.

I've never had to replug a tire after a repair.. Not sure I'd want to drive 100mph on a plugged tire but I usually don't anyway. As long as it's in the tread and not too close to the sidewall I'd be confident driving on it... Plus I added a spare tire to my arsenal.

Is this a rear or front tire? You have to live with a front for a long time, usually replacing the rears as a ratio of at least 2:1, sometimes 3:1. The longer you have to live with it the more tempted I would be to patch as well. It's an individual thing. Only you know how you drive and whether how you drive could risk a mere plug. I have had very good luck with plugs, and generally endorse them. But you should ask a professional if you are unsure.

No matter what method you choose, the tire has been compromised.
There is far more to the dynamic of a high speed tire than simply getting the plug or patch to stay in place.
Drive at 50mph, no trouble.. push the envelope, I would replace the rubber.
