Hey guys, One of those evening I was riding my PX Vespa, it was about 50 kph not more, probably less, when all of a sudden, the rear tire went flat in a split second, while cars all around me (city evening rush hour ) and in a middle of an intersection, the Vespa started shaking violently, It was real hard to control it, luckily I was not hit by a car. If I was in the highway, I would probably be dead. What shook me is how sudden the tire went flat. Anyway, a week later I purchased two Italian made tubeless type aluminum rims, no ebay, just went to the vespa shop, was'nt cheap but my life is worth more than 200$ !! I also bought tubeless tire flat repair kit to fix two holes in the Michelin tires.
Anyway for those who still ride these split tube type rims, I strongly suggest replacing them asap. Its a Russian, or shall I say Italian roulette ;-)

See if i bought the single rim type, would i need to buy new tyres or would i be able to use the tyres that i allready have?

Depends on what tires you now have on, if you ride tubeless type like the michelins s83, you are all set, tale them off the current rims and install them on the new rims.

Glad you're ok Rudi.
I had a rear puncture last week and it went down slowly because my inner tubes have punctureseal in them. The convenience of split rims can still be had if you use that stuff.

Puncture seal is an option too I guess Split rims convenient in what way? you still have to replace the inner tube while with a tubeless you just use repair kit on the spot, even in the middle of the road.

I meant the convenience of changing tyres in your own garage, relatively easy with a split rim. I could be wrong, but I was under the impression that you need specialist equipment to get them on a single/tubeless rim?

I've been lucky enough to only ever suffer one low speed blow out, no intention to convert to tubeless but have started using gloop (or other brand) stuff.
Wilkinsons sell it pretty cheap, Halfords also do it as cyclists use it..

the foams ok , carried a can all the time i was a despatch , but only for low speed get ya off the motorway hard shoulder use , never had to use it ,but, if used tubeless tyres cant be repaired afterwards , as gaz says a spare saves ya the bother , an arent we missin the point , you had a rear blow out n didnt "off" , not many can say that, most boast the scars ,well done , get some gloop , H

Heh! Had two rear blow outs in two days once, fixed the first puncture, but in my haste didn't see the small piece of sharp metal that had caused it had gone right through, and inside the tyre, so of course, it caused another one! Doh!

That goop stuff sounds good tho, wonder if we got something similar here in NZ?

Post by leishy62 on May 15, 2015 22:09:30 GMT
Can't find goop, but found something called "puncturesafe" don't know if any of you know it, think it comes from Blighty, but these products work on tubes?

Post by Robjack on May 15, 2015 22:29:11 GMT
Puncturesafe. That's the stuff I use. I knew it was something like that. It's been bothering me a bit trying to think of it, but obviously not enough for me to get off my arse and go into the garage and have a look.
I can recommend it Leishy.

How do you get the stuff in the tubes?
|

Post by Robjack on May 16, 2015 14:28:27 GMT
You get a little valve key that unscrews and removes the valve middle, then you put the plastic tube over the now open valve and squeeze the bottle to put in the required amount. Put the valve back in after blowing through to clean, then inflate. The stuff coats the inside of the tube when you go for a ride.

its all a tempory fix , it just gets ya home/nxt garage with air , an stops a puncture=blow out=tarmac testing , an take it from somebody who's extensively tested the tarmac , it always wins/hurts , tho the scars do give ya impressive braggin rights , but not worth the pain , H

it stops a sudden deflation in a tubed tyre ,giving rider a chance to pull over safely or limp home/nxt garage , without it tubes go flat fast an then spin an rip the valve off ,usually throwing the rider .by the time you feel it an wonder "somethings not right" an look for a pull over spot its happening too fast to react. i dont use it myself on any of my scoots or bikes ,too tight to buy it , on scoots i carry a spare an on the bike a recovery card ,H

i'm not in disagreement with ya , as i said i dont use the stuff myself ,just reporting what others have told me ,an have had the same doubts as you on its effectiveness with tubes . will ask my mot guy as he's a mountain bike nut aswell if he's heard same thing in cycle community as you.tho as he changes customers tyres he hates the stuff on bikes makes his job worse .H

As gazpx says nothing will stop a tube deflating fast if its ripped or torn. Goop fills a pinhole in the tube slowing the deflation down before it can increase to a tear. If you see what I mean ! As henri says it gives you a chance to stop under control. It wont cure a ripped tube but could maybe stop a "slow" puncture becoming an instant flat. So for under a tenner for both wheels to give you that chance I reckon its worth a punt. As for the mess it makes, if you've had a " bad one" both the tube and tyre should be binned anyway along with your underwear !
Cheers.

I had one once on the back. It felt a bit weird so I stopped and found the tyre just felt soft .So I changed it for my spare. When I got home about an hour later the tyre was completely flat. I took the tyre off and found a small nail in it and a tiny green blob of goop about a 1/8" round on the tube where it had been pierced and resealed. No mess on inside of tyre. Its not supposed to be a permanent puncture repair but a way to slow down deflation so both tyre and tube were replaced. Dunno what would have happened if I hadn't noticed but like I say for a few quid for two tyres worth of snot I reckon its worth it.
Cheers.

am on cookin duty so whilst a gallon of chili bubbles down to half a gallon ive had time to go "tinterwebbing" , an general theorys same as what i thought/believed . tubes get punctured by small object an start to deflate ,rider doesnt spot it or stop too check an then tube moves round rim causing a tear or valve loss =blow out .theres some very boring slow motion footage of tyre tests by manufacturers,i wont link em as you wont thank me ,15 mins of my life i'll not get back sort of deal. as for gazpx's "prove me wrong" , well theres only 1 way i know ,ride a scoot over a load of nails an see what happens , ive had my go at tarmac testing an lost everytime , job for a younger guy ,at my age you dont bounce ya break .not tryin to pick a fight gaz as i'm mostly in agreement with you on tubed tyres/gloop debate . i think its another 2 stroke oil/which kit/exhaust type debate that will run awhile . jurys still out on it chez henri .

People have spoken of Goop/Slime etc putting the wheels out of balance but ive never noticed anything personally. I cant tell you if it works, even although ive had it in my tubes for a few years. But i may find out soon as i need to change two tyres! Theres never any mess with Gooped up tubes either. Im not so sure that a tubeless tyre could be repaired if it has Goop in it? Will i still use the Goop? Probably It beats wrapping an old, cut up tube around the inside of the tyre anyday

^ agreed
I did have a bit of front wheel vibe post gloop, but only at speeds which should not be encouraged on 10" rims with innertubes :-)

you could always try puncture proofing ya tyres , stick a cut edge 8" inside ya 10" , i seen an done it on landrovers used in the woods ,no more thorn/nail/splinter punctures , where a weekly occurence beforehand , god knows what it did for wheel balance ,they where on military bar treads an never went over 30mph , well apart from being moved from site to site , an we mostly did that on sunday nights when roads was empty , H
