Tire plug fart

[moto-rama]

Now that I have a new pair of Road5's on my R12, the Nail Fairy found me in Santa Cruz, and inserted a big framing nail in my rear tire.

No biggie, it lost some pressure, but seemed to be holding at 32lbs, despite some leakage. I rode it the 80 miles or so home, and it still had 28lbs when I go there.

I got my plug kit out, and plugged it with a ropey cord and rubber cement. A repair I've done too many times to count.
I filled it to 36lbs, and checked it in the AM. Still at 36 lbs.

Success, right?

Today was the 2nd day, and before I was going to take it out for a short ride out to the beach, I checked the pressure.

20lbs.

What? I spun the wheel around to the repair and the cord had farted almost completely out of the puncture. I don't think I can recall that happening before.:nchantr

I took a photo, since it never happened if it isn't photographed.

What's next? I'd pull it out and try a new rope.

Did you do the quarter-turn before pulling out the insertion needle? That twists the rope on the inside into a knot, so it's hard to see how the rope would be pushed back out by the air pressure.

I don't know why some rope kits need rubber cement; the ropes I got do not need rubber cement - less mess. Does one work better than the other?

Either the hole is too big or the rope is too small. Pick one. "Glass half full" stuff.
Either way, I'd be looking for a new tire.

I learned to turn the tool a half turn then pull it out with a swift motion.

I used the plain rope plus cement plugs for a long time, or rubber ones with cement.
I got these cords in a kit and they were already treated with some vulcanizing goop of some kind.

The hole shouldn't be too big, since it was a tight fit. But the nail went in diagonally, so not sure if that's a factor.
I'll probably take to the guys in San Bruno (Motorcycle Madness?) and let them patch it. Plugs are not the best repair anyway.

I'm going to get it patched. I have a whopping 800 miles on this pair. Now if they had 3000 miles or more on them, then New Tire.
I've never had a problem with a plug, but prefer to have them patched from the inside. I did patches myself for years, but now I am too old and grumpy to be levering tires.

I gotcha. :thumbup
I wasn't being "Barf-preachy".
As someone who has mounted/balanced/repaired tires for a living and as someone who has experienced catastrophic tire failure at speed I fully understand both sides of the coin. I just hate replaying the image of the reamer violating the core as I'm tucking behind the windscreen. At that point I usually have other things I should be thinking about. I just write-off the cost of a new tire as insurance and peace of mind.

I recommend Ride-On tire sealant https://www.ride-on.com/ , I've pulled 5 or 6 nails and staples out of my current rear tire thanks to Harbor Freight's parking lot.

Did you use rubber cement when installing it? You can try using a thicker plug. Some plug kits come with some really thick plugs, so you gotta ream the crap out of the hole first.

I think this is more of a shart than a fart personally

So I used to work at wheel works, and anytime you buy a tire, it comes with a warranty and the patch(for legal reasons they dont allow plugs anymore?) your tire if it has a nail, or replaces the tire if the sidewall has a rupture.. does this apply to motorcycle tires too? assuming you bought it from a shop and had them mount it?

I am a perennial shit-magnet. If there is a nail, a screw, or a deer, it will be attracted to me as if I were a mini-black hole; so I typically end up with at least 2 plugs/patches in every rear tire I buy. I may also be the one person who routinely gets nails in their front tire.
BTW, that's why I wear a mask and practice social distancing. I haven't met a virus that I didn't get.

Looking at that extruded goopy cord thingy, I think you have a point. Since no one was in the garage to hear it, we may never know definitively if it was a "shart". Do sharts require an audience?

My tires were installed by my BMW dealer, in SF. For some reason, they gave me a great deal on the pair when I had it in for service. In fact I was a bit startled by the low-ish price. I'll ask them about road hazard warranty on Tues. Maybe they'll patch it for free? The last 50 times I got tires, I had Moto-Tire-Guy (Rest-In-Peace) install them. He had a policy, "NO Patches, No Plugs" . He did not want to assume any liability for a failed tire/patch.

I'm OK with replacing a tire if it's got damage that cannot be safely repaired, but if I replaced my tires for every puncture, man, that would be a lot of tires. I think I've had to patch or plug nearly every tire, at least the rears, in the past 10 years. There is just so much construction debris discarded along or ON our roads and highways these days.
Take a ride along Hwy 35 through Daly City sometime. The center rightofway and shoulders are littered with literally tons of construction rubbish, household garbage and nowadays, medical waste.
It's fucking disgusting. They ought to put up CCTV to catch the shitizens that are dumping all that crap. :afm199

I don't think any places will patch a moto tire for liability reasons. With that said the rear tire on my Tiger has 2 patches inside due to punctures--I have no issues trusting them.

When you buy a bike they will sell you on a tire hazard program but that's the only time i've heard of it.

That's impressive. I don't see how that can happen, even if you used the type that require glue, and skipped the glue. The glue type that I used recently are so tacky, I don't think it would've gone in without the glue to act as a lube. At least it happened in the garage!

I have gotten many new MC tires from the back of shops with a nail hole..
I just use a tube and ride till almost bald. With no problems..
My 2 cents...

I have heard the more powerful bikes will throw a plug, I went to the Norcal Dyno day and they told me that happened before.

 

[tzrider]

I've had a number of rope plugs do what yours did, typically in situations where there is a lot of lateral load on the tire. I found these and have stopped screwing around with the rope plugs: https://www.stopngo.com/

Moto tires are something I change a lot more than I "need" to. For the times I didn't (race track mostly) and my helmet was 2" from the surface of the track zipping by at 100mph, I'd pay $400 to get out of that moment in time. But, I'm not here to be preachy about it, its just my jam.

I know we've argued the merits of "shop local" vs. "online" before, but just want to say we are in complete agreement on this one! Patching from the inside has some merit, but plugs, nah. For me plugs just get me home.
