[Closed] Slime tyre liner- do they actually work?

I used them before going tubeless and they work great.

Edit: The tyre likes thorns?

Mountain King 2.2 Supersonic.

If it's thorny don't use really light tyres?

Slime liners are alright if they stay put, which they invariably don't, when they're worse than useless!

Go tubeless, much more sensible, although Conti SS tyres are among the more porous and take more effort to convert.

Slime are ok when they work - drawbacks are they are quite a bit heavier & impossible to fix.

In my experience:

Slime tyre liners: good! I've never had a problem with them slipping (either on my XC or CX bike) but that may be due to the fact that I run relatively high tyre pressures on my bikes coupled with relatively narrow tyres...

Slime inner tubes...I just don't get on with!

Last year one of my riding mates started using the liners combined with slime tubes, but he had several flats where liners cut into inner tubes causing large slashes that couldn't be fixed and tyres full of green goo!

I tried the tyre liners when I went to Spain this year as I was fed up with thorn punctures last yr.
I also bought some Spesh Enduro Flak Jacket tyres as I thought this might help.....

.....it would appear that neither helped and I had at least a puncture per day. One could even have been attributed to the liner, as there was some tearing/straining on a punctured tube that lined up in the exact curve of the end shape of the liner. There was a hole in the middle of this damage.

I ditched them after a few days and suffered no increase in puncture rate as a result.
It was also tricky when replacing a tube during a ride to centre the liner in the tyre, and there was always that feeling of 'did it just move?'.

Ok, how about spots/dabs of glue fixing the liner to to the tyre carcass?

I only use them in narrow high pressure commuting tyres. They've been great so far but I suspect running a wider lower pressure tyre with less of a curve across the profile may allow them to move about. Not sure if glue would work, they feel quite 'non-stick' to the touch.

Thanks guys. Makes sense that they would squirm at lower pressures. Im still not convinced by Ghetto tubeless though.

What's not to get on with, finally got round to try to fix my most repaired slime tube this weekend, 6 more patches added to the 10+ that are already on it, pumped it up and found another 6 punctures, bugger might be time to retire it..but they are ace tools.
Considering up to the point it went down, at least 11 punctures were being held up by the slime.

Run tubeless on another bike (came fitted) and haven't had any hassle yet, but don't see any advantage to me (s'not rocky round here, so don't need less pressure))

Less pressure isn't advantageous only on rocky stuff anyway, and it weighs a lot less than Slime tubes!

I've been thinking about putting a slime tyre liner on the rear tyre of my commuter too. Tried various tyres and nothing so far really resists glass punctures - not tried mega heavy schwalbe marathons yet.

Also tried slime tubes and wasn't too impressed. They seem to puncture far easier than other tubes and are a pain to repair. They give a horrible ride feel too.

if you are going to glue them in, why not go for the panaracer kevlar equivalents that are sticky backed? The slime ones come with an oily coating you'd have to remove before gluing.
I thought about the Panaracer ones, but it effectively adds £15 (I think that's what they cost) to any set of tyres you put them in, as they aren't transferable.

Worse than useless for me. After not really having undue problems with punctures I "treated myself" to new tyres (Conti Mountain Kings) new tubes (Slime filled) and the Slime Tyre liners, and looked forward to a puncture free future. The liners were a bit fiddly to keep in position but I figured it would be the last time for a year or two I would need to do it. I was planning a 40 miler the next day, mostly on roads and smooth surfaces so pumped them up to 60 psi.
Next day I had a puncture within 4 miles of starting off, then another at 20 miles. It was then that I realised the Slime liner was cutting into the tube like a stanley knife. The tube was scored all the way round. I took the liner out but the damage was well and truly done and I used up all my remaining patches and limped home stopping every 5 mins to top up the pressure. The tyre was full of green slime from the tube, and the tube was soaked with the slime rendering the patches unstickable. Total disaster! I'll be writing to those Slime people to see what they say.

Just use normal inner tubes with some Stans fluid poured in, they seem to work well enough for me.

I tried the ghetto tubeless route which was a swine to set up but they ultimately worked quite well in an "I'm not sure if I can trust them to last an epic ride) kind of a way. I figured that the loss of an inner tube which would only find it's way into my camelbak wasn't really worth the hassle.

I used them for a couple of seasons. 2/3 of thorns probably worked OK, but when they didn't they really didn't, and the extruding slime and mess made it harder to put a proper patch on.

Nowadays I'd sooner carry the additional weight as better quality tyres, so avoiding many of the punctures in the first place.

I found Schwalbe Marathons pretty useless on my commute. The only thing that saved them was the aforementioned Panaracer liners - but this did seem to make the tyre 'balloon' a bit and were a faff - but they worked, so may be worth checking them out.

Have Conti sport contacts on at the moment - have done around 4000 miles on them, and not a single issue. Not great off road though 😉
