I know riders who run tubes in all tires, tubeless or not, for safety reasons.--BANDIT

If you run a tube in a tire that is designed to be run tubeless this can generate more heat as it is just adding another layer into the mix and this can cause the tire to wear out prematurely. The whole idea of a tubeless tire is to avoid rapid deflation. There is a liner in a tubeless tire which when penetrated, wraps itself around the nail or rock or whatever has penetrated the tire. This tends to make for a very slow deflation. For example, (you can even do this in a bar and win money - bet someone you can stick a pin in a balloon and it won't delate) take a deflated balloon and put a small square of duct tape on a section of the balloon. Now inflate the balloon and stick a pin through the duct tape square. The balloon doesn't deflate.

Now if you have a tube type rim with a tubeless tire then you do need to run a tube in the tire.
