Saw this referenced in the MTBR 2014 best-in-show items from Interbike. Their comment:

Schwalbe’s Procore Dual-Chamber Tire System consists of a high-pressure air chamber near the rim to protect against rock strikes, pinch flats and burping. It’s surrounded by a tubeless tire—Scwalbe’s or anyone else’s—that can be run at extremely low pressure for improved traction and float. On paper, it’s a pretty compelling story—and we’ve heard a number of pros testing the system are very impressed—but we’ll have to see how it works in the real world.

Seems like good concept, especially the anti burping aspect.

...but at over $200 - plus tires - it's going to be a hard sell for anything other than downhill racing.

Seems to be a variation on the "run flat" tires sold for automotive use. I wonder how much weight it will add.

PROCORE system is a joint development with Syntace, but it can be mounted in all conventional wheels that have a minimum internal width of 23 millimeters. Weight per wheel is 200 grams and will be available in all three mountain bike wheel diameters.

Something that will add nearly half a pound per wheel will definitely be of more interest to the gravity riding set.

While I like the concept, I don't see it ever being accepted on the road unless they come out with a lighter weight, less expensive version. Even then, it would probably only appeal to the 'adventure riding' set.
