Sorry, I know there was a thread about this recently but just can't find it.
Still debating whether I need to change tyres for bigger excursions off road, but I reeeeeeally love how fast the Terreno XC in TLR flavour is.
I'm only really using the bike for gravel rides when the going gets just a bit too lumpy or the descents just a bit too long and fast, so tread is probably fine (I'm getting used to it on the corners) but I am worried about pinch flats in the middle of nowhere e.g. the Lairig an Laoigh...
Will they seal, or is the sidewall just too porous?
Am using Stan's Race.

It might have been mine, and I ended up with he TNT mainly for reliability on the Exposure 24/12 and because I got a Barzo for £32 in that flavour.
As far as I could ascertain the Tan wall version is "a bit thinner" and is hardly any less of a tyre to save about 60g of weight. I probably could/should have got it TBH but hey...
I've got tan wall mezcals set up tubeless on my xc bike, don't lose much pressure and no punctures yet. I've got a rimpact in the back though as it's a fancy carbon wheel. I'd be happy using them for longer rides/bikepacking but I may run a rimpact up front too.
The TLR tyres are tubeless ready (and listed as such on [url= https://www.vittoria.com/ww/en/tyres/mtb-xc/terreno ]Vittoria's website[/url]) but they are also available in TNT flavour.
I've been running the TLR (tan wall) 29x2.1" tubeless for a while and they've been fine (although I'm very much a pootler, so they've not been properly hammered).
They went on, up and seated easily (probably the easiest tubeless tyre I've used), but the problem was that they were flat as a pancake the next morning. I pumped them up again and they lost all air a second time overnight. I checked on here and apparently some tyres can take a while to seal.
I did pump them up and rotated them through water and you could see air beading out of the side wall.
Adding plenty more sealant (standard Stans) with some riding and spinning of the tyres finally sorted the problem and since then they've ridden well and probably just lose 5-6 psi a week. I pulled a large hawthorn out of my front tyre some while back and it sealed perfectly.
So, they run well tubeless but were just a bit of a faff to get set up initially.
I picked up some TNT Terrenos as spares and noticed that they weight around 700g. I didn't weight the TLRs but they're quoted as 600g on the website (although I've seen them listed as 650g elsewhere); I suppose that the extra sealant in the sidewalls of the TLRs might add a tiny bit of weight to this.
I'm assuming that the TNTs will hold air better from the off (although I'm a bit worried about the extra weight).
If you're concerned about the TLRs, Banana Industries have the [url= https://bananaindustries.co.uk/collections/tyres/products/vittoria-terreno-cyclo-cross-tyres-29-x-2-1 ]Terreno 29x2.1 TNT tyres[/url] at £22 (they've also got the [url= https://bananaindustries.co.uk/collections/tyres/products/vittoria-terreno-cyclo-cross-tyres-29-x-2-25 ]2.25"s[/url] for the same price).
My Mezcal TNT tan walls have been great tubeless - no leaks and popped onto bead seat positively and easily.
Did slash the sidewall on pointy rocks, but 2x Dynaplug sorted it.
@PJay - thanks, I think it was your thread I read previously (probably contributed to it too...) but I couldn't find it again.
Yes I'm a fan of the TNT Vittorias, my 38mm Terrenos and 33mm Terreno Wets have all been fairly impeccable once I sorted out my tubeless routine (seems installing with a tube first is the key to easy inflation and sealing).
The TLRs are fast and lovely with latex tubes and I'm not smashing through rock gardens, bike is basically standing in for gravel bike when the rides are more lumpy and less tarmac.
Only concern is that I might not get sidewalls all sealed up in time for my next ride, how many rides do you think it took for them to seal up? Don't want to be having to stop and top up mid-ride in two weeks time...

@sillyoldman - thanks, I've been carrying my Dynaplugs dilligently, good to see some practical examples of how to use them!
how many rides do you think it took for them to seal up?
To be honest I can't really remember. I wasn't riding much for health reasons when I bought the Terrenos, so the bike was stood in the shed most of the time.
Were as my previous tubeless tyres seemed to hold air from the off with the sealant just being there to deal with punctures, the tan wall Terrenos seemed to need the sealant to actually seal the sidewalls.
As above they lost all air overnight twice after which I added more sealant and spent some time spinning the wheels. After that they lost about 50% of their air overnight before finally sealing up.
There's nothing to say that your won't hold air better. I'd have thought that extra sealant and a few good rides should do the trick, but again yours might hold air better anyway.
Sorry I can't be more specific.
No that's fine, my 29er is similar, maybe sitting still for weeks on end then getting taken out, so I'm completely at home re-inflating almost flat latex tubes.
Two or three rides/re-inflations/spinnings of wheels would be fine.
Also I'm using Stan's Race sealant, although I don't think it would hold any advantage when it comes to porous sidewalls, I think it's mainly better for bigger holes due to more fibres or something.
Valves on order, will give it a shot!
My wife is on the tan wall tlrs. All went up fine and hold air fine with a 50/50 mix of stans/stans race. No difference in tubeless ability between the tlr and tnt ones.
I've been running the heavier Goma's tubeless with no issues, but they're a lot heavier (1100g)!
