Narrative:

Captain, PNF, aborted takeoff at 110 KTS after aural takeoff warning horn and aural slats alert heard. Abort uneventful and aircraft cleared runway 17R at txwys east, K, holding short of taxiway left. Maintenance contacted for advice. Recycling of flaps and slats completed with maintenance concurrence. Takeoff warning system checked with no abnormalities. Brake overheat light illuminated approximately 2 mins after parking brakes. First officer used temperature selector and determined both left mainmounts above 305 degrees. Right mainmounts indicated approximately 150 degrees. Satisfied that there appeared to be no problem with flap/slat system, captain elected to continue taxi to runway 18L and allow brakes to cool. Brake overheat light extinguished while northbound on taxiway K prior to reaching taxiway Z. Brakes were steadily cooling and indicated 220 degrees upon reaching runway 18L at taxiway Y. Captain requested further taxi south on taxiway east to give brakes more cooling airflow. While sbound on taxiway east, all brake temperatures were checked and all indicated less than 200 degrees. Clearance was requested back to runway 18L and ground control cleared us via txwys west, left, and F. While taxiing north on taxiway F, both right mainmounts deflated as aircraft passed taxiway wj. Captain stopped aircraft, ATC notified and crash fire rescue equipment requested. Captain contacted aft flight attendant for external observations. No smoke or fire observed so captain elected not to evacuate/evacuation. Visual inspection by crash fire rescue equipment confirmed 2 deflated mainmounts, no fire.
