Détails:
After landing at San Juan, the aircraft was parked at the customs area, then was towed to gate 15 and loaded for the next flight. The push-back was such that the crew had to taxi to the general aviation parking area and turn around before proceeding to runway 08 for departure. When cleared for takeoff, the wind was from 160 deg at 11 gusting 22 knots. At aprx 120 knots on the takeoff roll, a loud rumbling sound occurred which increased rapidly, then the aircraft began to vibrate. At approx. the V1 speed of 141 knots, the captain rejected the takeoff using maximum braking. Unable to stop on the remaining runway, he angled the aircraft to the safest area. The aircraft stopped with its nose in a lagoon. Due to trees, water, aircraft attitude and one accidental disarming, only 4 of 8 emergency slides were used. A lab analysis indicated that the #7 tire had failed due to low inflation, most likely from FOD. During the abort, its companion tire failed from overload. Black marks on the taxiway revealed the #7 tire started losing pressure while the aircraft was taxiing.
