Narrative:

After a normal landing day VMC; light winds; after slowing to approximately 100 KTS; we were informed by tower that they had seen smoking coming from our nose gear area. We slowed to 40 KTS before exiting on a high-speed taxiway. The nosewheel steering was jerky; not smooth. I assumed we had blown a nose tire. As we were exiting; we received many EICAS messages indicating a central system hydraulic problem. I stopped the plane immediately on the taxiway and informed tower we had a possible nose gear tire failure and a hydraulic failure and we were unable to taxi. Tower closed the runway as our tail was fouling the runway and the runway needed to be inspected for possible FOD from a blown tire. Tower also reported seeing no more smoke from the nose gear area. By this time we deduced that we had a center system failure due to total loss of center system hydraulic fluid. Operations was notified and a tug was sent to tow us in. I had the mechanic inspected all the tires and gear. They were all properly inflated and he observed fluid on the nose gear tires. We were towed in to the parking area and we all deplaned the aircraft.

Title: An ATC Local Controller notified a B777 crew of smoke near the nose gear during landing rollout. The smoke was hydraulic fluid from a failed hydraulic line in the nose gear wheel well. The aircraft was towed to the gate.
