tubed tyres

Having now got 3 out of 4 bikes with tubed tyres I realise I could be on borrowed time for a puncture so my question is what are the recommendations for fixing a punctured tubed tyre to "get you to a puncture repair specialist".

 

The assumption is not a catastrophic blowout requiring breakdown assist, more of a slow puncture variety.

 

I'm assuming the tubeless repair plug kit I carry on nc750x would be inappropriate so whats the solution when you dont want to remove the wheel. Is there any kind of gloop that can be squirted into the tube prior to re-inflating.

 

thanks in advance

I've got a subscription to the RAC. It seems to prevent punctures (so far). :)

Me got tubed tyres and a subscription to the RAC, as every year i end up on a break down truck due to a puncture.

 

RAC are first class in response.

Gloop put in after the puncture (so the nail doesn't keep making further holes until Gloop can no longer help) and soda stream cannisters if you are riding main roads and could live with a day on the recovery truck, another day waiting for a bike shop to open and order a tube etc. 

 

If you are going further, levers, spare tubes and making sure you have lubed TT tyres. With the right set-up you can change a tube and continue the ride before the RAC stop trying to sell you a holiday and actually send the truck. With TL tyres on unsealed spoked rims everyone without a press is stuffed.

ok via ins policy RAC recovery I have already. Will need to check what happens if I need to make the call in EU land. Might be tempted to carry a spare inner tubes just in case!

I carry a few patches along with my tubeless repair kit. I've used them I think a couple of times in the last 25yrs or so to help stranded bikers with punctures, one was an MZ and he had some levers but no patches/glue. It got him going again. I have the glue etc in the TL kit, so a couple of patches don't really add up to much extra to carry.

European bike shops actually seem to have a mythical item I believe is called stock. Contrary to opinion in English logistics and accountancy circles this is not a sort of thin gravy. Still, if you have tubes it's one less thing to go wrong. 

 

The trick with changing tubes at the roadside is starting with a set-up designed to be changed. I could get a Heidenau I'd fitted at home using soap, off the Triumph with a pair or 9-inch levers and back on with hands only. The OE fit, unlubed, TL spec Bridgestones came off with a hacksaw after 12 inch levers, bead breaker and driving the car over a plank placed on the sidewall had all failed. 

 

I only ever carried patches in the far north. Glue works better at hotel room temperatures and with beer at 8 quid a pint the fumes were acceptable. In warm places every town has a bloke with a gas iron who'll patch tubes better than new. None of your Thick Thick Fitter trying to sell you a new tyre when the air's past the sell by date.

Andy, I wish you were about to help the bike shop stuff rummage through their tyre stocks when I needed a replacement rear for the NC in France a few years ago. Of the four I found open none had the size in stock (to be fair two were really moped shops) and all said they could order in for 'demain'. I also tried some tyre dealers that advertised bike tyres as well but only one had any stock and they were sportsbike tyres. Of course they may have had tubes in stock :whistle:

I've only ever bought tubes in France. The one time I misjudged what tarmac designed for a Norwegian winter does to wear the place was that far North it was either going to be there and then or a week. They kept a Michelin and Chinese one in BMW F650 sizes. The price was about twice the UK one though.

Years ago, I bought a transalp 700 before realising it had tubed wheels.

i queried with dealer and they put in some sort of sealant before I collected bike.

it worked perfectly till I got first puncture.

the front tyre deflated instantly just I was coming to end of off slip from high speed dual carriageway.

minutes earlier and I dread to think what the outcome would have been.

i lost all confidence in the bike and it was traded in shortly after.

i would never buy or ride a tubed bike again.

The thing with tyre sealants used in tubed tyres is that they have to seal so much more than on a tubeless.

A tubeless has an airtight rim (pretty much) so when a nail goes through the only escape of air is from the single hole made. The liquid oozes out and thickens rapidly bringing the granulated rubber particles with it to block the hole or at least slow the release of air to allow a controlled stop.

With a tube the nail holes both the tyre and tube and the tube deflates the tyre deforms and the nail passes through the other side of the tube as well, or can do and as there is no rim seal pressure is lost rapidly and the tyre can move on the rim causing a much more brown trouser moment. Spokes add even more air loss although the latest bead rim spokes are supposed to be airtight.

The sealant has to seal the tube, the tyre and even the bead so has no chance really. The statement that these 'goops' work on tubes is pure marketing. The after a puncture sealant re-inflater aerosols also don't work on tubes as they line the tyre with a latex and can't do so to a tube that may have several spiked holes in it by the time you stop rolling on it.

Plug kits are no use to tubes so unless you can press the tyre sufficiently off to one side to extract the tube and patch it like you would a pushbike you are at the mercy of a breakdown service so the best tool is a mobile phone.

I would like to thank the advertising industry for:

 

Getting me back from somewhere in Latvia

Getting me from somewhere near Turin to Munich

Getting me off a trail above Ambleside and to work the week after. 

 

The failure near Bayeux is forgiven as I had by then decided to try putting the stuff in before the puncture and let the nail make 57 holes. 

 

I now live in hope that their hair gel and coffee capsules will eventually make me attractive to rich women.

I also had a tube with seven thorn punctures that had sealed when using OKO . (Farm stuff is cheaper ) only found out when changing the rear on my dirt bike . Now run mouses so saves this bother

It's the hope that gets you, Andy.

 

I'm still waiting for Valerie Leon to seduce me and let me demonstrate my Hai Karate moves! :ermm:  :whistle:

Off road only or a mixture? I looked at these years ago but the heat worried me.

off road only mate. wouldn't like to do a proper journey on tarmac they would overheat and suffer. wales in November though is no place to be changing tubes hence the mouses .

I've saw an Adam Reiman vid extolling the benefits of greasing the tube to eliminate snake bite punctures. it made sense because it don't grab the tube but he is an Aussie off rd demi. think he's now part of the ktm set up down under . look him up on the YouTube

has for the advert i imagine HR would have a gender fluid non binary baby now and you be signed up to the "all men are rapists" course :0)

was thinking about the way that hair gel and coffee would make Andy more attractive to women. i think i may have worked it out . he smears the hair gel in their eyes and then makes them a coffee to stop them going to sleep. i might just try this has the usual half bottle of vodka is losing its appeal now the polish bloke who used to make it in his garage has put the price up,  so its tad more expensive to woo these days. :0)

Do you know how old the tube was?  I was interested to read this:

http://www.stuff.co.nz/motoring/news/9705169/Motorcyclists-death-highlights-tubed-tyres-safety-issue

notably,

"..tyre manufacturers' recommendations - if a tyre is replaced then the tube should also be replaced".

 

However, other posters on here mention rapid deflation after a puncture, so perhaps following that guideline isn't going to keep one safe?

 

Asking for someone who's quite keen on the idea of the Guzzi V85TT, which has tubed tyres..

The bike was about 15 months old with original tyres and tubes

the bike was recovered home and I took off front wheel and took it for repair.

they fitted a new tube as they said this was best.

the bike was gone not long after.

It's false economy not to replace tubes at the same time as tyres. I always saved the old tubes as spares, a used one is better than a patched one. 

 

Grease makes sense but you need to make sure it's compatible with rubber. I'd simply soap them on fitting to help reduce the chances of trapping. Simple bar soap, warm water and a cheese grater makes a suitable slime. It always amazed me that soap would still be there months after fitting and made an actual difference to getting the tyre off the rim. You can understand a TL design is going to be an utter swine, but soap changes a TT from a struggle to easy. 

 

Moto Guzzi rims on the Nevada were bad. Safety bead, TL tyres fitted at the factory, very shallow well. Took them off with a hacksaw but had to take the rear to my tyre fitter to get the new one on. He told me never to bring the tubeless V7 ones back either. For this and other reasons I'd buy the GS if you want this type of bike and want to use rather than own it. Guzzi have lots of other features driven by fashion not use in my experience.

I hope the RSPCA don't find out! :whistle:

 

The tubes must get very icky after a while, with all that blood, guts and sh*te. :P
