Just reading the instructions for Stan’s sealant and they recommend 148ml for a 2.5” tyre! Bloody hell - that means you only get 6 tyres worth in a £30+ bottle. £5 per tyre and it has to be topped up at least once a year. Crikey! I’ve only been putting in 50ml since 2008.

Do you use the recommended? 1/3 of a pint seems like a lot to me.

I just use art latex in ghetto tubeless conversions. Water it down 50% and start with 100 ml per tyre.

If your tyres have been sealing with 50 ml, just keep using 50 ml.

If you think that's expensive, try setting up a pair of 4.8" fat bikes tyres tubeless!

That's more than any brand I've ever used. I just buy a big bottle of something that's on offer, and they are generally around 80ml for a big tyre. I go a few ml extra the first time to account for coating the inside.

A good squirt, then a bit more.

Almost certainly not 148ml though.

Can't say I've ever put more than 100ml in and that would be a new tyre.

Certainly be shopping around for the Stans too...never paid RRP, last bottle was circa £20 for the 946ml

i'd say i'm about 40-60ml. Depends how much glugs out, but when i've taken back out, it's about that.

I go Stans and recently bought a Quart discounted.

With Stans I tend to use about 90ml for a fresh tyre and 60ml for a refit. Just changed my 2.8” tyres yesterday after a year and there was still plenty of liquid sealant left. Small Stans bottles are 60ml, so I’ve always just used an old one as a guide.

Stan's No Tubes Tire (not Race) Sealant bottle says, "Bicycle Tyres 2.5-4.0in...use 3-4oz (90-120ml)"
I've just realised that online has different numbers; 2-3oz (bottle) for my tyres, but only 2oz online, so I'm +50% grrr. Glad you raised this

I've just got a bottle of cheap OKO Offorad stuff - think it's meant for tractors. £10 for 1.25 litres - Watered down 2:1 means it goes even further and costs peanuts. So far so good. Even when watered down it was wanting to seal up the syring I was using to inject it into the valve stem, so ability to plug holes looks good. Used about 100ml in a 2.5" tyre, and a little more in the rear where the tyre insert stops it sloshing around as well.

£5 per tyre and it has to be topped up at least once a year. Crikey!

True, though how many inner tubes did we used to get through at a few £ each?

I use about 80ml in tyres that are true 2.4 - Ardents, Spesh 2.6s etc.

Gave up on OKO sealant, wasn't very effective at sealing holes. Had a couple of leaks that just wouldn't seal long-term and it doesn't seal leaky sidewalls very well.

Artist's latex is ~£10 a litre and watered down up to 50-50 works well. It dries in the end but can be peeled off, that's just the time cost for the £ saving. Once a bit has dried on inside it takes very little liquid sealant to seal average holes.

Do you add anything "bitty" (I couldn't think of a more appropriate word😁) to the latex? I've seen glitter recommended, or is the latex enough on its own?

A couple of stans cups usually. Full ones for a new tyre. Maybe 4/5ths full for an older one. So guessing at 90-100ml.

Almost none. The last tube I threw away had 23 patches on it.

I just pour a generous amount of stans race straight in as it won't go through a syringe. I'd guesstimate about 100-120ml? In the scheme of things it's pretty cheap still, these days it's getting harder to find a pair of tyres <£100, so £6 worth of sealent, or £9 (splitting the difference on assuming I wear a rear tyre out and maybe swap the front to the rear when I refill it) over their lifetime isn't so bad.

I’ve just got a bottle of cheap OKO Offorad stuff – think it’s meant for tractors. £10 for 1.25 litres – Watered down 2:1 means it goes even further and costs peanuts. So far so good. Even when watered down it was wanting to seal up the syring I was using to inject it into the valve stem, so ability to plug holes looks good. Used about 100ml in a 2.5″ tyre, and a little more in the rear where the tyre insert stops it sloshing around as well.

It doesn't work particularly well, I persevered with it while I had a fat bike. I asked On-One as they were importing the bike specific OKO stuff and apparently the tractor stuff uses synthetic latex whereas the bike stuff uses natural which is why it costs twice as much (and works).

True, though how many inner tubes did we used to get through at a few £ each?

+1

Mid range tubes were 3 for £12. Nice ones were £8+ each. Even repairing them I suspect they didn't last a year on average before a valve ripped out or the tube itself perished in storage.

Almost none. The last tube I threw away had 23 patches on it.

I counted 32 cuts, flints and thorns in my winter road tyre last time I changed it. At ~10p a patch that 60ml of Stans is looking good value!

Good effort. I always had to bin a few from pinch flats that were almost impossible to repair reliably.

No need, just latex. It forms chunks/lumps as it dries anyway. I used to ride in the Chilterns, Ridgeway and Wilts downs areas so would get my fair share of flint cuts, used Superglue Powerflex on the larger cuts and the sealant did the rest after the glue gave it a head start.

No, just plain latex.

I use 100ml in 2.4" 29er, plus 25% for the Rimpact so 125ml. Joe's guidance is 60-120ml http://www.joes-no-flats.com/%7Chash%7CJOESWORLD/689/How-Much-Sealant-Should-I-Use%7Cfq%7C

2 of the little bottles. I've no idea how much that is though.

The oko hifibre ime is really good- seals as far as I can tell as well as stans, but being water based is brilliant- it doesn't dry up the same, even though I now keep my bikes in the house, and you can just add water if you suspect it is drying up. And it cleans out way easier of course.

One of those 2oz bottles (I keep an old one as a measure and because the spout fits the valve stem) seems to do for a new tyre.

For top ups one bottle does both front and back.
and the £30 bottle in my hand fills a 2oz bottle 16 times.

But I contend with thorns (particularly hawthorn) not flint round here.
