What is the point of tubeless tires?

Seriously, what is the point of these things? What problem do they solve and is it worth the extra maintenance hassles for non-racing riders?

You have to have tubeless rims. Otherwise you can use any tire you want. You can use extreme racing tires. Even pretty large punctures can seal almost instantly with the right sealing compound. No detectable air loss.

If you DO have a flat too large for the sealing compound to work which is possible, they make a device that puts a rubber plus in sealing the hole. I haven't even heard of anyone getting a hole that large. I do know one guy that picked up a carpet nail and left it in clicking on every turn before he got home. He said that when he pulled it out the tire got soft but sealed. He pumped it up and still rides it.

Besides being lighter and having a lower rolling resistance tire you also don't have to carry a flat kit on you. Frank tells us his flat his weighs 1/2 lb but mine - two innertubes, two CO2 cartridges, the filler tool and levers in a pack weights 2 lbs. This is more weight than my Look 206 delta pedals.

I have had no trouble at all with my Michelin Pro4 Endurance tires since converting to tubeless. Before I had flats so often that everyone around here runs Gatorskins which are heavy and have lousy traction.

You can run Pro4s tubeless? Hmmmm. I have a bunch of Pro4s and a tubeless ready wheel set with OE valves in a bag somewhere. Maybe I'll get some sealant and give it a whirl.

As an aside, what I don't like about tubeless ready rims and regular tires/tubes is that the tire beads practically weld themselves to the rim. It's a pain getting the tire off the rim, and they're really tight getting tires on the rim. All that is necessary if you're running tubeless but not so necessary with an ordinary tire/tube combo.

I noticed that too. Annoying. Everytime you change a flat you hear the tire bead pop into place. Or not...

I'm surprised that those who want to avoid flats don't just use foam filled tires instead of these or other Slime-like concoctions.

You could argue about 60g of inner tube vs 60g of goop, and
people do, but I have to assume you have never ridden a foam
or urethane tire.

If you have an innertube it rotates with the wheel and needs to be accelerated or decelerated. If you have sealant it rides more or less at the bottom of the tire not requiring to be accelerated.

There's horses for courses I suppose but after trying these for several months I like them.
