What Are The Advantages Of Tubeless and Why.??
Title says it all. Why go tubeless.?? Advantages and what are the physics/science/engineering of the advantages.??
I honestly don't know.

No more puncture flats. Everything else is supposed, as far as I'm concerned. I mounted the 700x35 Hutchinson Overide on my CX bike on January 18, 2018. It's logged 5,000 miles without a single issue, and no care beyond topping off sealant. My last flat tire of any kind was around 10,000 miles ago-- and that was due to running over (of all things) a pair of drywall screws. On 700x25s, I ran over a door hinge screw in September, and finished the last 15 miles of a century with the screw thwap-thwapping against the pavement. The next morning, the tire still had ~70psi in it. But little punctures, like goatheads or radial tire wire? Gone forever.

Add to puncture resistance PIA to mount and change when needed. Lighter, faster, better riding and handling. The advantages are endless. You will be a super star on tubeless! It is all the rage.
Would I do a round the world tour on them? Nope. May as well keep things standard with tubes as eventually that is where you will be in the middle of India or in Podunk Oklahoma. .
On my short commute bike have not had a flat in 20 years running Conti tires and standard tubes. Long commute bike have not had a flat in 5 years running Conti tires and standard tubes. On my daily workout bike have not had a flat in 3 years running Conti tires and standard tubes. Not bad for the lowly, easy to deal with standard tube set up.

Whet tyre sizes are you talking? IMO it's much more useful in mountain-biking where it allows you to run lower pressures without getting pinch flats, meaning more grip. All I can say is that I've gone from a flat every couple of weeks to none in two years.

You can run tubeless with lower pressures without risk of pinch flats. I run my tubeless at 60 psi. More comfortable and efficient.

My 29er mountain bike with Schwalbe Rocket Ron tires and standard tubes set to 28psi front and rear, never had a flat in. Rock gardens, rutted trails, roots, etc., o flats in 3 years. No longer mountain ride, only road now. Body weight 230 pounds. Again, not bad for the lowly standard tire and tube set up.

I'm currently running tubeless on my mountain bike and my road bike. Flat protection is the main reason. I've ridden through the last 37 winters on roads covered with cinders and sand. It's no fun changing a tire in 20ºF temps.

28 psi is high, not low. For example, I run 18f/20r tubeless.
It’s not surprising that you haven’t flatted in rock gardens, rutted trails, roots, etc. since pinch flatting while using tubes is really dependent on speed, tire pressure and sidewall stiffness.
If you lived in an area where flats were common from thorns you would understand another reason why folks run tubeless.

Disadvantage: Having yourself and your bike sprayed with sealant.
I too get very few flats. I'd rather simply change a tube than clean up a big mess.

If you live where you don't have goatheads, and you "never get flats" just run tubeless tires without sealant. As a guy with 5 sets of tubeless wheels who runs tubeless tires exclusively, I'm the first to say they're not for everyone. But you guys who go years without flats talking about how tubeless is unnecessary... yeah it is, for you. On the other hand, I would be looking at 50+ flats every year. And when the choice is between the tubeless tires and the "hassle" of sealant or using heavy, awful, armored tires, I'll take the tubeless.

I think every post here has missed my point and question. WHY DO YOU GET LESS FLATS WITH A TUBELESS TIRE.?? I asked for the scienc/physics/engineering of WHY does one get less flats by going tubeless. WHY.??

In the time it took you to post, read all the replies, and post again, you could have found the answer to your simple question. In fact, it would have taken much less time.
p.s. You never asked why you get less flats with tubeless.

I tested the Dura Ace 7850 wheels to see if they could hold pressure with no sealant and I would say that they did, but not in a real confidence inspiring way. I pumped up to 88 psi in the early afternoon and by the next morning the pressure had dropped to 50 and a day later it dropped to 25. I’m not sure if the initial pressurizing would be sufficient for a 3 hour ride or if the gradual loss of pressure would be a glaring deficiency....

After that, assuming one uses sealant in the tire, small punctures will be sealed. As an example, a month or so ago, I found an orange smudge on my rear tire. I peeled the orange off of the tire surface and found a nice orange spot where the sealant had sealed off a puncture. I hadn't realized that I had punctured and don't know when it happened.

But now that you managed to formulate your question, but are still not able to do the most basic of searches.......
No tube to pinch flat, and sealant will plug most punctures. Do you need more explaination than that?

A lot of mouthy people on this forum. I've noticed in other posts, you're one of them.
And as for google searches.... Why would I do that with all the experts here.?? You want me to read wiki and be satisfied.?? I use google as little as possible. They're biased, at least. What a stupid response.... Use google.?? Why is this forum active if we have google.?? Post a bike thread here and be told .... Use google. Asshats.

First off, because there is no tube, there are no pinch flats.
After that, assuming one uses sealant in the tire, small punctures will be sealed. As an example, a month or so ago, I found an orange smudge on my rear tire. I peeled the orange off of the tire surface and found a nice orange spot where the sealant had sealed off a puncture. I hadn't realized that I had punctured and don't know when it happened.

I didn't ask because I didn't know, dick. Or jimmie. Your post was a waist of my time and yours, georgey. Fiurther more, how do you know that I haven't searched it out.?? Am I suppose to believe everything I read.?? Can't do that. Not in this day and age, dudette.

You're wrong buddy. Read the post. You're assuming I already knew that tubeless creates less flats. That's your assumption, not mine.

The result is often a "snakebite" in the tube:
When you take the tube out of the equation, this kind of flat is eliminated.
Other advantages of tubeless include less weight, better traction, and more comfort.
I only run tubeless on my mountain bike, as that's the bike I'm mostly likely to get flats on and the one that benefits the most from the advantages listed above. I should probably convert my gravel bike at some point.
Hope this helps!

When an obstacle is hit hard enough, the tube gets pinched between the tire and the rim:
The result is often a "snakebite" in the tube:

When you say you run tubeless tires without sealant, I have a follow up question for you: What pressures do you run then? I’m assuming you are talking about a road bike tubeless, since I would think that bigger volume tires always require sealant.
And then also I would like to know: when running tubeless without sealant, how much pressure do you lose overnight?
I tested the Dura Ace 7850 wheels to see if they could hold pressure with no sealant and I would say that they did, but not in a real confidence inspiring way. I pumped up to 88 psi in the early afternoon and by the next morning the pressure had dropped to 50 and a day later it dropped to 25. I’m not sure if the initial pressurizing would be sufficient for a 3 hour ride or if the gradual loss of pressure would be a glaring deficiency....
I run my 700x25s ~90psi. Overnight they will lose a couple of pounds. If left for a week, those tires will drop to ~75psi and just sit there. Losing more than about 5psi overnight is usually a sign the sealant needs to be refreshed-- but if the sealant is still good, something else is leaking, usually the Presta core.
