Tyre sealant
 

At the moment I've new tubes with no puncture sealant, though I've used it in the past. The tyre fitters suggested this stuff has no value when you have a puncture and unbalances the wheel.

I had a rear wheel puncture last year (masonry nail) and the tyre went down like an Italian centre forward even though sealant was installed (notably at 70mph on the motorway)

So, my question is..has anyone used it and found it worked when they had a puncture? Is it worth the bother?

I'm personally not a fan of the stuff for the same reasons your tyre fitters suggested.

Sealant doesn't really help much in this sort of situation anyway as the tyre will still go flat, generally the sealant requires the tyre to be re-inflated to actually do any sealing job.

I do use it in my wheelbarrow tyre though! ;)

Haha....not easy riding a wheelbarrow....

Only put air in my tubes...

Helped a guy try to fix a flat in the middle of no-where
he had that "slime" stuff in his tube still went down...
when we got the tube out the slime had come out though the hole
with out some form of solvant to clean the tube we couldn't
get the patch to stick... lucky for him I carry a 19" tube as a spare...

Tyre sealant worked once for me but the second time failed completely (not sure why). Also, the green stuff spread everywhere inside and around the wheel / tyre (through the spoke joints).

Not bothering with that again.

I've tried sealant and it's not for me either, good idea in principle.

I've had problems with it snotting up the valves when adjusting air pressure, then resulting in a slow leak. Instead I've gone for thicker tubes and carrying a repair kit.

I was under the impression that tyre sealant was meant for tubeless tyres? I use it on my mountain bike after I converted the wheels to tubeless.
On short trips I carry a canister of "Tyre weld" or similar which can inflate and fill the tube full of a foam sealer which usually seals the puncture. But then I'm prepared to replace the tube later because a decent repair is very difficult due to the sealant.

I've had it on good advice that thicker tubes are a bad idea...friction and heat....this from a chap running his own tyre business for 30 years. I think with tubed tyres all you can do is carry spares..there's no silver bullet if you get a puncture. Thanks for your feedback chaps.:hello2:
