Narrative:
Upon rotation out of laredo; we felt a slight bump or thud as the aircraft left the ground. The crew agreed that it was most likely a gust of wind; not strong or loud enough to be alarming; just noticeable. We landed at destination with no problem; the aircraft touched down; stopped and taxied normally. During postflt the inboard tire on the #1 side of aircraft looked like the entire tread had been peeled off the aircraft. The tread had wrapped itself around the wheel between the strut and the remaining tire; and around some of the braking mechanisms; stretching part of the tire over the brake line and evidently breaking the line causing a steady flow brake hydraulic fluid leak. Maintenance and a hazmat team were called to clean up the spill and fix the tire.

Title: E140 EXPERIENCES TREAD SEPARATION ON MAIN GEAR WHEEL ON TKOF WHICH STRIKES HYD BRAKE PLUMBING CAUSING A LEAK.
Narrative: UPON ROTATION OUT OF LAREDO; WE FELT A SLIGHT BUMP OR THUD AS THE ACFT LEFT THE GND. THE CREW AGREED THAT IT WAS MOST LIKELY A GUST OF WIND; NOT STRONG OR LOUD ENOUGH TO BE ALARMING; JUST NOTICEABLE. WE LANDED AT DEST WITH NO PROB; THE ACFT TOUCHED DOWN; STOPPED AND TAXIED NORMALLY. DURING POSTFLT THE INBOARD TIRE ON THE #1 SIDE OF ACFT LOOKED LIKE THE ENTIRE TREAD HAD BEEN PEELED OFF THE ACFT. THE TREAD HAD WRAPPED ITSELF AROUND THE WHEEL BTWN THE STRUT AND THE REMAINING TIRE; AND AROUND SOME OF THE BRAKING MECHANISMS; STRETCHING PART OF THE TIRE OVER THE BRAKE LINE AND EVIDENTLY BREAKING THE LINE CAUSING A STEADY FLOW BRAKE HYD FLUID LEAK. MAINT AND A HAZMAT TEAM WERE CALLED TO CLEAN UP THE SPILL AND FIX THE TIRE.
