While I was aware of the term Tubeless Ready or TLR, I thought that pretty much was just saying that the tire had some material on the bead seat that let it seal up to the rim as opposed to other tires that had a pretty hard bead seat that didn't shape itself to the rim as well.

However, now I'm seeing tires online advertised as Tubeless, not TLR. And I'm not seeing a corresponding model of the tires in a version that indicates it's for tubes. Maybe the retailers just aren't carrying them.

Some of the googling I did came up with some not too informative articles that suggested Tubeless Tires were thicker in the tread. But little on any differences that might make tubing them a bad thing.

I'm not ready to go tubeless, I'm running on Mavic Open Sport and Mavic Open Pro rims. About 14 mm inside width IIRC, and 25 mm tires.

edit... I didn't recall correctly. The rims say 15 mm for the internal width.
