I just bought a new home and there is construction everywhere. I had a roofing nail in my tire that I sheered the head off of at the autocross yesterday. I drove the car while flat at 50mph all the way home which is about 30 miles. When I got home I plugged it and it is now not leaking, the question is would anyone have a problem driving on that for the next 3k miles or so. Some say you can not plug runflats, others say since I drove on it its now no good, what does everyone think?

Replace that tire.

you are not supposed to plug runflats. No doubt it can be done as your car is an example, but I would replace

From Discount Tire: You can plug the Bridgestones, you can't plug the Continentals. I think I drove 7,000 miles or so on a plugged rear tire with no issues.

I've got a plug in one of my OEM Goodyear NCT5 RFT tires and I've put 1K miles on it so far... No problems.

After I posted this I did a search, there were a few people who had driven a couple thousand miles on a pluged tire but didnt see anyone who drove on it flat prior. I'm not too concerned about the plug but the fact that I drove on it while flat for some distance. Normally I wouldn't even ask this question and just go buy four new tires like I'm dying to do anyway, but I just bought a home and am on a spending freeze so I'm rolling the dice on this one. I will be grandma'in it in the right lane, so if I have a blow out I will be on here preaching to everyone about the importance of tire safety.

Generally speaking, most shops will not plug a run flat tire after it has been driven in a low pressure condition.

My wife drove at least 30 miles on a run flat, had it plugged (properly from the inside) and drove on it for ~another year. It then had sidewall damage (during house rennovation activities at the house) and was replaced.

I can't see why driving on it ruins the tire if you keep the speed and thus temperature down. She stayed on city streets so she could keep it to 45mph or less. Most of the time she was around 35mph. I think you need to drive as if your tires are compromised (they are) like you should on a "donut". Driving normally on a donut isn't a good idea and neither is driving around like the tire is fine on a run flat. If the donut is at 60psi it will support the car but has minimal surface area for traction. The run flat has the area but will get hotter easier. Both will be smaller in diameter.

I had a nail stuck in my tire b4 and was slowly leaking air before, it never went flat so I don't know about your situation. Anyways i was planning to get winter tires then get another set of summer tires after that. Its been about 3months ~ still no problems.

Noop! Run Flats are repairable just like a Go Flat, but with certain restrictions:

Regardless, looking at what they cost, I'd try a repair and see how it goes.

Can always pick up a used one off of here or ebay.

Washed the car the other day and noticed my rears were smoked at 11k miles, so I ordered a set of Dunlop Zll's. On a related note dealing with the tirerack was as pleasant as always, the tires were on my doorstep in less then 24hrs. Anyways I got them mounted this afternoon, so far I've only driven home so I have no remarks on the tires, I went with 225/40 and 235/40 so I am eager to brake them in an get to the autocross. So back to the reason for the update, when they took off the tire with the hole this is what was found, long story short I had dodged a bullet.

wow, that tire does look bad. Good thing you go it replaced

I guess i understand the "you don't repair runflats" line from the perspective of a shop that assumes the tire has had some zero pressure operation regardless of what the customer says. But it just isn't true when the tire goes flat from a leak in your driveway. I've had this happen, i my only option (besides replacing the tire) was to learn how repair it myself with a plug kit. I did, and never had any problems with the tire again.

I would suggest if the tire has actually been run flat replace it.
If it has just lost some pressure or gone flat in the driveway then plug it.
