Vittoria tub crazy puncture

vpnikolov

Did the Great Escape today, tub got punctured almost midway through. Put in some sealant, DID NOT fix the puncture at all (couldn't see any debris stuck in the hole.

Got home and put the tub in water, the following happened:

Air coming out from the sidewall like this? On a new tyre?

Potential warranty claim? Justifiable?

cycleclinic

the tube has failed could it be a pinch flat?

vpnikolov

How does that even occur on a tubular tyre? :?

The tyre got punctured in that area on the tread, 1mm hole.

Matthewfalle

Did you catch the tyre on the barbed wire fence?

vpnikolov

If only that was the case... It was a small pothole actually. Nothing out of the ordinary for UK roads. Meh, not a great first experience on tubs, the tyre lasted only a week. This is becoming too expensive too quick.

sungod

a small puncture can do that

which sealant? some are useless

Apart from the tub itself, pray tell what is causing the too much expense too quick?

Tuto extreme, probably I should use the Vittoria pit stop going forward.

No, Extreme is better, but you need to make sure you actually got sealant into the tyre - the nozzle on the Extreme bottle can clog really easily, and it's surprisingly hard to tell if enough went in. Pitstop can work, but deals less well with larger holes or multiple punctures. I had 2 x punctures this weekend (main and spare tub) and eventually got the main tyre sorted with sealant after I figured out the bottle wasn't flowing properly.

Tubs are expensive. I had two go on one ride. £120 and not repairable. I don't bother with them now.

Err not really: it's like anything, prices vary both due to which one you use and where you buy them from.

A couple of Conti Sprinters will last for years and be really good and cost you £50. Conti Giros are £12 and are bombproof and look and work well phat. Obviously go for top end stuff and they are expensive: I think the Corsas on the s/s are something silly like £65 RRP, but you'd be a mug to pay that.

Shame you stopped using them so quickly.

I used to use tubs as a schooly when tubs were so much better than tyres - but then tyres really caught up.

I've had a staple slice through a Tufo Tub - even with sealant in - that was a write off - and then two Conti 4000S tubs go in the space of a mile or so. I'd save the tubs for big events - but I was getting so many more flats on tubs than I ever did on tyres - it made me very uneasy using them for big events. Sold the sprint wheels and went back to tyres and never looked back.

If a tub is ruined by a puncture, a tyre most likely would be also. A hit hard enough to split the inner tube can write off a tub and it can also write off a tyre. Unfortunately the state of the roads in the UK in particular is so varied that it's impossible to say what would be the best choice.

Conti sprinters aren't bombproof, no tubs or tyres are.

Its mainly luck, a nail or shard of glass will cut through any tyre. A solid tyre might resist but do you really want to ride a solid tyre?

You take your choice, tubs are great, they give a better ride and are the best option for racing but riding nice tubs in an area with busted roads might not be the most sensible thing to do.

If your tubs last for years, you are lucky but aren't really riding much.

used every day for commutin', trainin', racin' and going down to the pub.

Never had any issues.

But I'm not going down this road again - see posts passim for the extrapolated versions and me getting me and more bored .............................................

Agreed - a tad of P7 will take out even the hardiest rubber tyre. But they are pretty darn ninja.

Imagine if Trump went to drop another MOAB and Da'Esh covered themselves in Conti Sprinters and survived the blast that way. That would be crazy and a brilliant advert for Conti.

Hmmmm. I think mileage is a more reliable indicator than age. That said, if your tubs will endure "years" of daily racing, commuting and training then count me in, Continental have clearly discovered the Holy Grail.

fenix

Clearly MF has stolen some of the luck that I never had when riding tubs ?

tufo is waaaaaaay better than vittoria pitstop

judging by the video it doesn't look like there's a huge puncture (though you don't say what pressure this was at)

as mentioned above, you need to get the sealant in there which sometimes isn't easy, about a third of a bottle is enough, shake it very well before squirting it in

replace the valve, position the wheel so the sealant can pool where the hole is, and inflate

worst case you can open the tyre up and repair it, though this is more complicated once there's sealant in it

On the video the tyre is at about 100 psi, pumped before putting it in water. Just couldn't fix it... I will change the tyre and hope I won't have such issues again.

Same as yours I think.

sungod

at 100 psi it must be a small puncture, it definitely should seal ok with tufo extreme, sounds like you've not managed to get enough of the sealant to the right place to do the job, put more in, it's better than binning a near new tyre

fwiw last year i ran two corsa g+ tyres for months with multiple punctures (they cut like crazy on wet roads), all sealed ok with tufo extreme

vpnikolov

I have filled the tyre twice now, no luck with the sealant. Nothing is coming out of the hole on the tread.

sungod

the hole in the inner tube can end up away from the puncture in the tread

another thought - if you're using a valve extender, is it tight/sealed to the tub stem? i've had that fizzing sidewall effect with air bleeding from the stem into the carcass

if you can't fix it and don't plan to repair the tub, you'll have to cut it open and tell us what's going on!

vpnikolov

And that is what I did!

Results are - there was sealant around the area of the puncture, but not enough by the looks of it. There was lots built up around the valve, like a deposit.

Now... how do I clean up any glue residue from the tape?

sungod

which tape?

vpnikolov

I used Tufo. The whole tape came off fine, but there are small patches of glue left on the rim.

term1te

Use a hair drier to warm up the patches of residual glue, then rub or peel it off. Should come off cleanly.
