I'm looking into a new Specialized StumpJumper Alloy and the shop suggested going tubeless.
What are the pros and cons of tubeless mountain bike tires?
Fair enough. But after 20 years of tubeless, it’s pretty obvious the advantages outweigh the disadvantages. Especially now that bacon/dart type repairs are so effective. The early days? Not so fun to flat.
Tubeless is a little lighter, less rolling resistance and generally more puncture resistant. Also lets you run slightly lower pressure for better traction and comfort.
Thanks for the replies, seems overwhelmingly pro tubeless!
How often do you have to put in more slime on tubeless ones?
Do you need a compressor to air them up?
Are they more puncture resistant than the thicker tubes?

I've never really agreed with this. If you are able to lower your pressure with tubeless, you could have lowered your pressure with tubes, since you weren't banging your rims on the ground. If you do bang your rims on the ground, you'll be pinch-flatting...and that happens with tubeless too. More supple for more traction due to no tube resistance, but wider rims for better sidewall support and bigger volume tires are the real game-changers IMO for pressure...and then there's inserts.
A few things. Tubeless don’t generally use slime (the slime tubeless sealant isn’t great), but specific tubeless goo like Stan’s, Orange Seal, Muck Off, etc. how frequently you add it is dependent generally on temperature, and how much you add. I usually add some about every 6 weeks in the summer.
Some tire/rim combos require a compressor, some will air up first try with a floor pump. There is little rhyme or reason to this. Watch some YouTube tutorials!
traditional punctures become essentially a non-issue, they usually seal up if small enough. But as mentioned, you can still snakebite on the rim, and still slash sidewalls on shale and such. Watch some tutorials on using ‘bacon’ to fix punctures when they happen.
Feel free to ask more questions, we can answer some things!

It depends a lot on setup, conditions and riding style. With tubeless I have always been able to get away with a lot of light rim dings without damaging the tire or rim that would certainly take out a tube, especially with carbon rims. It is a different story with my hard tail which gets a lot more smashy smashy treatment, but the weakest link is the rims. I have several dents in them yet no flats. Which is fine by me considering tires almost cost as much as aluminum rims do anymore.

I'm in AZ, cactus are big enough to avoid, it's those little goathead stickers that are a problem.
However, I've found that the green tube slime works just fine to seal up any of those. Not sure I'm ready to make the change, but seems to be the way to go.

Has been a long time since I have ran tubes but sealant in a tube worked well for me for punctures. However sealant in a tube will not help with pinch flats and is the heaviest option going. If it is working for you certainly no need to change, but going tubeless can be the cheapest and most noticeable upgrade you can make. So carry on, but if you ever feel like you want to upgrade something on your bike I'd suggest going tubeless over more expensive bits and pieces.
