Didn't have my glasses with me so I couldn't see the very fine print that might have had a part number or such. Similar for the Open Sports.

Both are marked 622 x 15C. I'm thinking C is for clincher. I'm not wanting to go tubeless. I just wanted to know if there was anything physically different about a tire marketed as tubeless that made using them with a tube any worse than using a tube with any other tire.

So far it seems the term is more important to those that are tubeless, than it is for those of us still using tubes. Though there are some minor points that were brought up.
