Yeah, ones called thornproof - they're really thick on the outside, so more difficult for nasty pointy bits to penetrate.

They seem like more of a weight penalty than Mr. Tuffy, so I'm not into them.

Then there are Slime tubes. Work OK on low pressure tires. They do require a bit of work to keep the slime out of your pump and from clogging up in the valve. I used to run those in the desert, good against goatheads.
