Technically, tubeless tires will run hotter, with tubes inside of them -- but we have no choice, as tube-only tires are pretty much non-existent anymore. Just be sure to replace the rim strips while you have the tire off. The rim strips are rubber/plastic strips which cover the spoke nipples, preventing them from puncturing your new tubes. Always put new tubes in new tires! The natural rubber tubes will deflate slower, when punctured, than synthetic rubber tubes, as well, but I don't know that it will make much of a difference. Deflation is bad... Very bad. New rims strips, and new tubes. I'm just sayin'... Cheers!
