Default Tire puncture: to plug or not to plug

Puncture in tire 1/2 inch from sidwall. Would like to keep the OEM Pirelli P6s for another 10,000 miles and then replace all with summer tires. Is 1/2 inch from sidewall too close for a plug?

If it were me, any excuse to replace the crappy P6s would do.

Whats a hot patch? If I have to bring the car in for service, I'll just replace the tire. Have had lots of luck with patches in the past but this is closer to the sidewall than in the past.

Crappy Pirellis- maybe not the best handling tire in world but these tires can take a lot of abuse. Have run into curbs with them and driven them for miles over unpaved roads without incident.

Patch the tire and keep the patched one on the back

But watch it to make sure the patch holds and doesn't develop a small leak.

With our wheels if you ever get very low on air a small pot hole or curb hit will develop a bubble on the sidewall

A Hotpatch is Vulcanized to the inside of the tire, obviously it requires the tire off the rim so the average pump jockey won't do it, personally I wouldn't plug a sidewall puncture.

as long as the puncture is in the fist tread block you should be fine, check the angle of the puncture with a pen or something hard to check to see what angle if went in by. if it is going toward the sidewall then it becomes a problem, it could have scrapped against the sidewall weakening your tire and causing it to sooner or later blow, if it is away from the sidewall toward the middle of the tire you should be fine.

in all honestly though take it somewhere to get it patched, the filler plugs that you can buy at autostores suck, they will eventually come out. if you take it somewhere you can have them plug and patch it for a double saftety and it works very well.

Agree with the hot patch. This will run you the cost of the patch plus remount and rebalance. Probably $25 for all.

I have had good luck with plugs throughout the years, though they have fallen out of fashion since I was in the auto repair biz. The reason is probably because a successful plug is very technique dependent. Also tire failures due to underinflation and other problems have really made headlines in the past decade. So I'm sure tire shops have moved to the stronger (and more lucrative) repair method, i.e. hot patch.

Your puncture location sounds like it might be near the edge of the steel belt. Not a recommended place for a plug anyway.

Like Ctrlz said... If its near or on the shoulder of the tire you cannot patch it because that part of the tire flexes too much - you'd still have a leak. I just went through this on my wife's car... She has more flat tires than any one I know (other than her sister).

Thanks for the help guys. Did not plug this one myself. Had it patched at the tire store. So far so good.

The Hot Patch has been around a lot longer than the plug, and is far more reliable, even on the sidewall. The rubber is actually vulcanized, won't leak. It is not a cold glued on patch. Plugs took over because they were less labor intensive/faster and a guy could keep a plug kit in his glove box.

Maybe I was just lucky, but I've plugged a hole very much on the corner of the tire.. it worked just fine. I keep a plug kit in the trunk. Best $8 I ever spent.

So good to see another Cary native on here!

I am going to have to agree with some of the others... the last 10k miles on those tires are going to be loud and annoying. Just go ahead and fork it over while the economy blows and feel safe... you will also notice a much quieter ride.

I punctured one of my Pirrelli P-Zeros back in October with an industrial sized screw. It actually went straight through the tire and cracked the rim. $400 later I had a new rim and new tire!

I have to vent...

I have had a TERRIBLE day today and just when I though it couldn't get worse, it did. Its now 1:00 A.M and I have a fully flat tire (tires have less than 1000km on them). I'm travelling tomorrow to Texas for my spring break, so bring on the hot patch Hopefully my ****ty *** jack won't break. If that does actually happens, this would simply fulfill my day.
