Tyre sealant

[daggavis]

Question for techies?For a el cheapo solution to better puncture resistance, is it worthwile putting Joe?s tyre sealant in my inner tubes? Tubes are much thinner than tyre tread so will the sealant seal holes in my tube? Or should I rather use tyre liners? Or both?

Sounds like the experience I had in 1976 and reported here on

wreck.bike. When I was riding my last Clement tubulars, that had poor

stitch protectors that caused many pin hole leaks, my tires kept going

flat. Knowing about the ability of the butterfat in milk to plug such

holes, I poured a few ounces of milk, from a dairy on the Klausen pass

in Switzerland, into my tire pump and pumped it into my tires. This

solved my problem, but a few weeks later, back home, while riding to

Santa Cruz with a bunch of bikies sitting on my wheel, I had a rear

blowout and sprayed them with putrid milk, while I had a hard time

controlling the bike as it slid around on the flat tubular like ice.

 

This was my encounter with sealant and it taught me that Sealants are

about as slick as butter inside a tube. You can try that by just

feeling the slipperiness of a tube that has the stuff inside.

 

Are you sure your tale didn't originate from my experience. The event

sounds so similar.

You cant get the sealer through the valve into a tube.

You can... I use the cheapie pink Raleigh brand goop from Checkers/Hyper... In my Shamals no less... No punctures...

 

[Dirtbreath]

Please explain. You pump tyre sealer into your tube though a normal presta/schrader valve? You dont have to remove the core?

[daggavis]

I'm sure i can make a small hole with a decent syringe and just patch it afterwards..

[AndreZA]

Take a lekka fat syringe and inject the sealant into the tube. Seal with a patch just to make sure. If it's a Shrader tube then just remove the core, inert sealant and put back core.

 

 

[bob_the_builder]

I have done it both ways... I never said without removing the core was easy or clean...

[daggavis]

Ok, but will it seal the tube or will it just spray the sealant between the tyre and tube? I watched the video on Joe's site where they claim they only used normal inner tubes and not tubeless..flippen hard to believe as the inner tubes must have looked like a sive with al the holes..maybe it was tubeless and the wording is wrong..

[Dirtbreath]

Sorry guys but I dont understand:

 

1. Are you saying they put sealant between the tube and the tyre?

2. I think they mean a non tubeless tyre that seals with their rim strip.

 

Havent been on Stans website for a while but need to check this out.

[bob_the_builder]

Ok, I use currently, Conti something tubes, GP4K clinchers, and the pink goop from checkers in the tubes... No punctures, no goop between tyre and tube... Goop inside tube...

[Dirtbreath]

Nice one.

 

When you are ready, step up to a tubeless conversion. Fewer pinch flats and the ride is better. You can also ride lower pressures which helps on rocky terrain.

Daggavis, I take it that you are talking MTB here.  THe "Slime" to put into the tube is a concoction of glue and rubber bits.  Its the rubber bits that close the holes and the glue that congeals it into place.  So the slime will close the hole in the tube and the tyre.  TYre liners are made of plastic and not rubber, thus the irritating effect of "reopening" the holes in the tube.  (so don't mix liners with slime)

 

Obviously, I have been converted to the dark side, and realise that tubeless is the way to go.  THere are a number of very successful "ghetto" conversions, which require double rim tap, lots of insulation tap, a value (from an old tube) and 4x the usual slime.  (but others can fill in the messy details-  ie slowpoke)

[Bikalot]

so konafan are you saying if you have tire liners and slime its not making your wheels"double" puncture proof but cancelling the effect of the goo?

 

wil the goo stuff work in road tubes?it should shouldnt it?

 

and lastly how much tire pressure will you use before it seals?

 

thanks

Continental have been supplying tubes with removable valve cores (presta) for some time. Easy to fill with sealant. Some of their older tubes with non removable cores are still around so check before you buy.

 

Locally produced Sludge seems to be one of the best sealants available and now comes in different compounds for road and MTB. Sludge supply Schwalbe in Germany who market the stuff in Europe under their own label of Doc Blue. The box states "Made in South Africa" which is just great!

[daggavis]

I bought Dr. Sludge from sportmanswarehouse for 36 bucks a 250ml bottle (couldn't fine Joe's but R500ml retails for around R160)and injected it with a 10ml (flippen small) syringe without a needle, patched the hole and also fitted tyre liners. The sludge is much thicker than joe's.

Did the lionman mabalingwe race on saturday but alas no punctures..so i can't comment on the effectiveness of this combination. There were alot of people who puntured on this race. I didn't even notice the added weight on my wheels..will keep you posted
