Hi everyone,

I just ran over a flippin nail and the pressure went. My questions is, I have a HPDE event next weekend. Would I be ok running on a patched tire? Its a CMP in South Carolina.

The tire is a Goodyear Runflat Gen 2. I ask because there are only 1,000 miles on the tires. Its the left rear if that matters

Thank you

How far did You drive it without air? If there is a ton of rubber dust inside, just go ahead and get another tire.

didnt lose complete pressure. It lost about 8 pounds before I shoved the nail back in. the pressure is stable at 28 lbs. I have a appt at 330 at the dearlership but if a patch cant hold up at the track event, then I guess I can suck it up and get another. I just hate to throw this tire away with perfectly good thread and only a 1000 miles on it.

A patch will be fine as long as the tire didn't lose any integrity. Sounds like you will be good to go though.

Well the nail blew out about 15 miles out so I lost all pressure ad had to drive about 15 miles on it. They are repairing it but said its not recommended to do so.

So has anyone done a track event on a patched tire before?

I wonder if driving on zero pressure damaged the integrity of the tire.

I have run a track day with a tire that was properly patched without problem. It all depends on where the nail hole was in the tire and what type of plug/patch is used for the fix. Most tire shops have a new design repair system for this type of tire. It is a cross between a vulcanized patch and a tire plug. The inside of the tire is roughed up and glue applied then the stem of the patch is pulled through the hole filling it. The round base adheres to the inside of the tire like a standard vulcanized patch. Excess stem is cut off. The driven on run flat is something else entirely and very questionable in my mind for track use. Would I run it NO. A tire is $300 or so, what is a potentially damaged car or your injury going to cost - your decision. I'm also going to be at CMP next weekend with NASA #54 Black C5 Z06. Look me up.

Very cool. I will look you up. If it were 300 I wouldn't mind but it's 540 for the tire. I will prolly get a new one. I'm just bitter I guess since the tire only has 1000 miles on it and I basically have to throw it away.

I've run track events on properly repaired run flats.

Take a look at this Goodyear document:

In there you can read:


So.....if the puncture is not too close to the sidewall, and if the the repair is done correctly with a patch-plug, then the tire should be good for the track.

I just ordered new G:2's for the front as I corded one on Mondays event. Dealer matched Discount tires quote of 500 each. Me, if you're going fast, I would order the tire. If I wasn't doing a track event, I would just plug and run it.

Yeah, it sucks that I needed new front tires at 5300 miles.
