Slime/Gloop/OKO etc; puncture sealants for inner tubes.

Has anyone actually found this stuff works? I mean by having it put into the tube prior to an actual puncture. As the bikes come with inner tubes fitted (ridiculous in the 21st century when for a few extra quid manufacturers could fit sealed spoke wheel rims) I have Gloop in both inner tubes, in the hope of if not completely sealing a puncture it may at least slow deflation.
Most of my motorcycles for the last 20 years or so have had tubeless tyres so roadside repair has not been an issue. I don't like the idea of having to carry tyre levers and trying to effect a repair myself. I have roadside rescue and recovery cover, however it's not unusual to hear of folk waiting several hours for assistance.
I have been present on a few occasions where a fellow rider has suffered a puncture with a tubed tyre. It seems that the tube often tears rather than remaining just a hole. Inflation with the sealant in an aerosol can has failed, and removing a tyre from the rim to effect a roadside repair has proven impossible due being unable to break the bead.
I know several riders use the above type sealants, I would be interested to know it has actually worked and sealed the puncture.
I'll be needing new tyres soon so was considering paying out for a tubeless conversion which does seem an expensive option to expedite a roadside repair.

I had it in both tyres on my last tubeless bike. I never suffered a puncture in 55 thousand miles, but it was there in case I did. The mechanic in the shop I used to get my tyres fitted, sat me down once and explained why sealant was a bad idea, bad wheel corrosion and catastrophic tyre disintegration where the sealant is disguising a rip. Anyway, he said, why bother when plugging a tyre takes just a few minutes.
I do use gloop in my inner tubes for the reason you state, and to give me perhaps enough inflation to ride somewhere safe and dry to repair the puncture.

This year I bought myself some tire tools and learned how to use them. I find it affirming to have the ability to complete certain tasks on my bikes, tasks that can be left to others, but not by everyone. The latest technology can be very convenient, though in my professional life I see the failure points of that every day. Proven technology that can be stripped down to its component parts has virtue and soul, it is repairable. I choose to have things in my life that are user serviceable. Your mileage may vary, that is your right as an individual.

In the heyday of the RV125 Suzuki VanVan forum (& Yam equivalent ) tried & tested was OKO tyre sealant.

Main reason being the oversize rear tyre & tube was often a pig to get hold of and nigh on impossible off the shelf and we spent lots of time offroad. Did it prevent punctures who knows but those with it installed didnt suffer flats

Inner tube sealent is a bit of an oil thread subject imo & tyre fitters hate it

I know tyre fitters hate it in tubeless tyres as it gets everywhere. Having had a bollocking from my local fitter for using the stuff in tubeless tyres I never used it again, other than what's now in my Interceptor tubes.

I’ve had one flat on the road and one close to home afterwards due to pinching the replacement tube. Sealant from Flat-out is now added to better my chances and I carry tools, patches, and tubes to cover my bases. They don’t market to road going light vehicles but do support tubes, sealant life is beyond the tire’s, and does not cause corrosion. Even if a road side repair isn’t wanted, I at least have the supplies to repair in a local shop or at a hotel and feel more confident having spooned on my own tires. That said, plugs are much easier but I would use a preventative sealant there as well. My tube failure was from not noticing a low tire condition from a very slow leak, I’ve not developed one since.

That's my experience as well. I had a puncture in a tubed tyre and used some gloopy stuff (can't remember the make) to get me home. The guy who replaced the tube was not impressed because it just causes a mess.

I raced desert bikes for years and always used Slime in my inner tubes. After one race I was looking the bike over and found 8 nails in the back tire. Tire pressure had dropping from 18 psi to 16. I’m pretty sold on the stuff.

I got a puncture on my interceptor, tubed rear. I had a bottle of agricultural slime type stuff, larger reinforcing fibres in it than stuff I've used in cycles. Had to pull the valve core to get it in, got me home, but it looked like a mixture shite and slugs when I popped the tyre off. So, it gets you home, but be prepared for the clean up.
