…when you can just bung in some latex and save a whole bunch of weight? Same goes for UST rims I guess (speaking as a man who just shelled out on a pair of Mavic 819s. Oops….)

yes, I think UST tyres are worth it. Primarily for the reinforced sidewalls but I guess it can depend on what you ride, where you ride and how you ride it.

They're an awful lot less hassle than any DIY rim sealed system.

As a heavier (15st+) rider, yes.

Well sweet jesus, ah may just go and get me some then! 🙂

I think it depends where you ride, I've never had the slightest problem with my regular Nevegals, and they're not even particularily tough tyres but some geography's harder on tyres and sidewalls, maybe if I lived somewhere slatey I'd want proper UST. Certainly no benefit for me though as it stands, so far as I can see.

The SWS version of the Nevegal could be the best of both if sidewall cuts are an issue….

I just couldn't be bothered with the hassle of trying to seal non-UST tyres. USTs are simple.

Hassle? 1st time everytime here and I've tried: Vapours, High Rollers, Mountain Kings, Spesh LK, Mud X and Nevegals. In fact been tubeless for 2-3 years and never used UST.

If you ride in a rocky area don't think you can beat it.

Add to the above the ease of fitting compared to some non-UST tyres.

As for hassle, once you get the hang of it(!), running regular tyres as tubeless really is so ridiculously easy. So are UST one's really that much stronger? What is is it exactly that they do to make it "UST"? Considering on some models you could be saving as much as 200g per tyre, I think this is a really big deal!!

They have a different bead which hooks up to and makes a seal without the need for a sealant to UST rims which is why I have found that some normal tires will not go tubeless on UST rims as they don't make an air tight seal because of the difference in bead (Schwalbe being a prime example)

So are UST one's really that much stronger?

In addition to the bead that Rotor Stern has mentioned, UST tyres are inherently airtight – you can actually run them without sealant but you'd lose all protection against things like thorns, nails, glass, etc. This is why they tend to be heavier, as the tyre itself is more robust.

+1 for real UST.

UST tyres don't need sealant to be puncture proof(but it helps), thorns will plug up their own holes nicely.

Half way house like bontrager tlr or the specialised 2bliss seem like agood bet to me

once you get the hang of it

There's no "hang" to get with UST
