Worth going tubeless?

Ended up with a dnf yesterday after a puncture and was wondering if it was worth going tubeless?

My wheels are tubeless ready so would just need some sealant and valves I think.

Would tubeless reduce chance of punctures or would I be better off just playing with higher pressures (I was running 35psi front and back@ 76kg)

I did a MTB Orienteering event last year, the farmers had been out cutting loads of hedges I passed a lot of people with punctures, back at the finish the people who were running tubeless had no problems, I run them on the CX and MTB I think it is worth it if it stops a DNF.

Depends why you punctured. If you had pinch flats (snakebites) then higher pressures might be worth a go. Pressure depends on tyre width and slightly tyre type as well as your weight. If it was pinpricks, sealant might instantly repair them well enough to finish.

If you get a puncture with a tubeless tyre, do you just whack a tube in?

Serious question by the way. Having only once had a tubeless motorcycle puncture I can confirm the can of gloop was useless fixing a nail through the sidewall.

Putting a tube in is about the third response to a puncture.
1. In theory, the sealant will duly seal it, mostly without you even being aware you've punctured. Occasionally it'll take a while to seal and it's obvous since some sealant sprays out for a short while before sealing the hole. In practice I've had one of the latter type in 21,000km of using tubeless and it took about a minute to seal and lost only 10psi (of 75psi) in that time. All other punctures sealed without my knowing about them until I took the tyre off (at which point you can see clumps of sealant over the holes).
2. If it doesn't seal then you can use small, purpose-made strips of rubber pushed into the hole. I've never had to do that.
3. If that doesn't work, putting a tube in certainly should. I've never had to do that either (though I've practised to make sure it works, and it does).
4. Huge gashes in the sidewall are going to need a tyre boot or a new tyre. In the former case, sticking said boot to the sealant-covered rubber may not be as easy due to the sealant, but is allegedly still possible.

Thanks for comprehensive and logical reply. Maybe I'll go for tubless when I wear my rims out

I would have answered the same as SofV, I have taken 14 thorns out of one tubeless tyres when checking at service time.

I would not go back to tubes in the MTB.

I carry tubes as a contingency on my tubeless road bike BUT: 1) is it possible to avoid slopping the redundant fluid everywhere and, more importantly, 2) if the conditions are such that the tyre has failed what are the chances of avoiding a repeat? Conclusion, always have the means to pay for transport to base.

You can convert them easily enough, YouTube has lots of videos

Same with me
I experienced that with my mates on weekend ride
Through a path of fresh cut hedgerow ...4 mates all punctured
I had around 7 thorns in total on both wheels but no loss if pressure
Even good when a mate instinctively pulled a thorn out

The tube / tubeless debate can get as heated as the helmet debate or viz vest debate.

I tried tubeless and when it works it works well. Most people never have a problem with it. But when it does arise, it can be a pig to fix at the side of the road. I switched back to tubes as it is never a problem to fix. Its a personal choice.
