I'm getting the car ready for Road America this weekend and noticed that there is a nail in the left front tire. It's in the middle of the tread, so it can be repaired. Would you trust a repaired tire for the track? I'm a little worried about it. I don't know what else to do because I don't think that I can get a replacement tire at such short notice.
XSIVEONE Do a search on the forum about repaired tires. Some where there is a link to a Goodyear Tech Bulletin and how many patchs (as in many) can be on the tire before there is a limiation.
Folks I as an Engineer who works with aircraft I am tired of folks making judgement calls based on personal feelings. Why cannot anybody realize that companies pay folks the big bucks to write Tech Bullentins and the information in them better be right, cause if they are wrong there is one BIG lawsuit.
I three choices here.. I can leave a tiny pin hole leak. I can have the tire repaired with a plug/patch. I can forget about going up to Road America this weekend because there is no way that I'll find a tire now.
BTW.. I just pulled this off of a search on this forum..

FYI - AT our discount tire they have a plug/patch which will allow the tire to keep it's speed rating with up to 3 repairs. It is applied from the inside like a patch. It has a plug attached to the patch so you are getting the benefits of both. Had one in my first rear after only 2000 miles. Held up perfectly for the entire 8000 mile life of the tire.
After someone posted this, someone with 30 years of tire experience said it was ok.
The question now is if I should trust a repaired tire for the track because that's not clear in what I've been pulling up in searches.

WHEELS & TIRES – The wheels should be round without any dents or damage to the mounting surface. The tires should be in good condition. The tread should be above the wear bars. No cords or belts should show. Flat tires repaired with plugs should not be used as these could fail under the high stress of track conditions. Hubcaps or beauty rings should be removed. They can come off causing a dangerous situation for you & other students.
I've known for a while that plugs should not be used. My question is about it being repaired properly from the inside.
The hole is dead center so there is no threat to the sidewall, I believe that you will be just fine for the event at Road America.
Thank you! I just re-read Dave's post now. I took it the wrong way before. I see now that he disagree's with Zippy's comment about not trusting the tire. I read it wrong and thought that he was agreeing with him at first saying that he would NOT track the car with a repaired tire.
Anyway.. I have the wheel off the car right now. I'm about to head to the Goodyear dealer. They're going to dunk it and check to see if it is a leak and that I'm not just imagining something. If it is leaking, I will have it plug/patched from the inside.
Option 4; I will most likely be at Road America but not participating, If you do not trust your tire we could possibly swap a wheel and tire for the event. My tire has about a 1000 easy road miles on it.

Sorry I was trying not to be to point blank and in the process I was not clear.
Goodyear gives a patch a green light and does not effect the tire rating.
I have trusted patches enought that I have been down the TWS straight at 145 mph and never give it a second thought. IF something happen I could come back to Goodyear as they have something in writting that said it was OK.
Here is what I was looking for:
Look for this thread titled "What the F*#@!" It has the link to the Goodyear bulletin
Thanks again for the information! It was a close call, but luckily I didn't have to deal with it. I just got back from Goodyear and they dunk tested my tire and no leak! The bad thing though is that I'm running late and I'm going to miss the free driving seminar tonight. Oh well.. This was MUCH more important to deal with.
I've done in excess of 175 mph on a Z06 tire with a plug in it several times. Of course, that's just me.
MEE TOO I have a friend who has a tire shop about 20 minutes from my house .He would not even charge me to patch my tire.....However I am soo lazy that,whenever I see a nail,in any of my tires,or my family memebers cars tires,I just plug them.Yes I did say plug... Its fast and convenient.. ..I have been doing these for 18 years now(since I was 17) ...18 years ago,the cheaper plugs,used to leak ,because they would dry out.That is why they got the bad reputation.....But now I would plug any tire in a heart beat...I still believe that patching(dismounting the tire and applying a cold patch from inside) is better way of repairing the tire,because the chance of a slow leak,with a correctly applied patch is zero,where as with the correctly applied plug,the chance of a slow leak might be,one in 100..Like I said I've used plugs,on all my relatives and family members cars.Probably we are talking on average,I plug at least one tire a week...None of them has ever leaked or caused a BLOW-OUT... ..I've have raced at speeds,over 120MPH(Willow Big Track),all day with my Z06,with more than one plug in my tires..By the way those tires were replaced with new ones,after they served their purpose(15K miles of semi hard life) they were slicks They never leaked..In my opinion,"you have to alway patch it",is a nonsence..part of a sales pitch.. If some of you disagree with me,I understand.But please bear in mind that I am talking from a personal experience...YOUR RESULT MIGHT VARY....
I think most likely you would be fine with a plug, and definitely with a patch. I would think that even it the plug or patch began to leak, you would loose pressure slowly, and the car would start to feel sluggish in turns, giving you an indication that something was wrong.
However, I did plug one of my front tires, and decided to go ahead and get another one to run on the track. I had time and could afford the $150, ? is if that tire did blow at 140 in the front what is going to happen? If I didn't have time to get a new tire I would do the patch, and if I couldn't do that I would still probably run with a plug rather than not run the event. In summary, I would say patch it and run it.

Get the facts from Goodyear!!!!
Dave: Sorry to get you so upset.....not my intention. Your correct, my reply was personal feelings, and not based on any research data. I am an Engineering Technician at Detroit Diesel Corp and have experience with test data, engineering reports, etc. So, I agree completely with "getting the facts" before making decisions.
I would NOT race any car with patched/repaired/plugged tire, but that's my personal choice.
Zippy then you know how anal us Engineers can be. In the Aerospace business we live and breathe by Tech. Bulletins. Depending on the Tech. Bulletin there can be literally ten of thousands engineering of hours and testing hours that have gone into. I am in the business were pulling to the side of the road is not an option.
And you did step on a land mine in regards to patching tires, as I knew of the Goodyear Bulletin. A lot of this has to do with my issues with a lot of posts on this forum. People's personal feelings become fact, and physical realities are thrown out the door.
I guess this is a curse of being an Engineer where you understand too much and it takes too much time just explain the science behind the issues. I got into a debate about Aerodynamics with someone well know on a lot of forums. Basically to an Aerodynamicist he show his absolute ignorance on the subject. Yet the audience was completely clueless. I felt like I was Urinating in a Dark Suit. I got a warm feeling and nobody notice.
