Narrative: [There was a] nose gear tire issue followed by a loss of System A Hydraulics. We were flying Flight XXXX from ZZZ to ZZZ1 on (date). As we were rolling down the runway; we heard a loud bang from the nose gear area. It went away as quickly as it arrived; engine parameters were normal as well as directional control. After the takeoff; we talked about what it could have been. During the climb to our cruising altitude; we decided to call ZZZ Tower back and ask them to inspect Runway XR for any clues to what had happened during our takeoff roll. It took a while before we got an update from ZZZ Tower. They had found a two feet by two piece of rubber. We immediately contacted Dispatch and Maintenance; and we discussed various options. We were now in cruise and still bound for ZZZ1; when all of sudden the Number 1 Eng Hyd A LOW PRESSURE light started to come on and off a few times. We got the QRH Checklist and ran the HYDRAULIC PUMP LOW PRESSURE.I looked down on the instrument panel and noticed the System A Hydraulics quantity was down in the low 20's percent. We could watch that number was dropping fast. We now went quickly over to another chapter in the QRH; to LOSS OF SYSTEM A. We also [requested priority landing] with Center; and they immediately gave us direct to ZZZ1 airport. We determined that it was likely that a possibly piece of rubber had hit some of the Hydraulic lines. We quickly updated Dispatch about our loss of Hydraulic A quantity; and that we had [requested priority landing]. Dispatch gave us the Landing Distance information data; and we compared it to our own. We were all in agreement to continue and land in ZZZ1. We informed our Flight Attendants about our situation and what they could expect from our landing. We flew overhead ZZZ1 airport; and manually extended our landing gear per QRH. After completing all the steps in the QRH; we lined up with Runway XXL and landed. I immediately noticed the tiller was «locked» and unusable upon landing; and had to use rudder and differential braking to get back on center line. Both NORM and ALT nose wheel steering where both unavailable. We elected to stop the aircraft on the runway; and asked the Fire Trucks to visually inspect the aircraft from the outside. After getting the OK from them; we had Company Maintenance meet us on the runway with a tug; and to tow us clear of the runway. We had just cleared [Runway] XXL when the tow bar snapped; and they had to get another one. Once we got the second one; we were towed over to Gate X where our passengers were able to deplane.


Second narrative: Departed ZZZ Runway XR. On takeoff roll; prior to rotation; a noise was heard similar to a hand slap on the front of the aircraft. Takeoff was continued with no adverse indications. As we continued to climb; the Captain and I assessed the probable cause of the noise. ZZZ Tower was advised of possible FOD on the runway. Before we were out of range of ZZZ Tower; we inquired for any findings of the FOD. Tower advised a piece of tire rubber was found on the runway. Still unsure whether the rubber was from our aircraft or a piece we hit on takeoff roll; we continued the assessment. Dispatch was brought into the loop and we all agreed to continue. As we continued to discuss the current situation; the #1 HYD LOW PRESSURE light illuminated and we ran the HYDRAULIC PUMP LOW PRESSURE QRH Checklist. SYSTEM A HYDRAULIC quantity was noted to be around 20 percent. SYSTEM A HYDRAULIC quantity continued to drop. LOSS OF SYSTEM A QRH Checklist was started. [After] reassessment of the loss of HYDRAULIC SYSTEM A and the noise heard at takeoff; [they] led us to believe that we had blown a tire which had damaged the hydraulics. A [priority landing was requested] with Center and direct ZZZ1 was issued. We continued discussions with Dispatch; as well as informed the Flight Attendants of our current conditions; plans and what to expect on arrival in ZZZ1. All went as planned with the completion of the LOSS OF SYSTEM A Checklist and landing on Runway XXL in ZZZ1. The only unexpected item on landing was no nose wheel steering on landing. Both NORM and ALT nose wheel steering was inoperative upon landing so we were unable to exit runway. CFR (Crash Fire Rescue) met the aircraft on the runway to assist. Aircraft was towed to the gate from the runway.


Synopsis: B737-700 flight crew reported hearing a loud bang from the nose gear area during the takeoff roll. In flight; the hydraulic system malfunctioned and the crew performed a manual gear extension prior to landing.
