Narrative:

Taking the runway of we felt a bump akin to taxing over a light up a little harder and thought it might have been a concrete seam. Taxi into position and hold without notice of a different plane feel or capt noticing nose wheel steering issue. Takeoff roll passing 100 kts and just before 113 V1 speed a shimmy started and got severe at 120 kias. Past V1 and no steering issue or slowing in aircraft acceleration we continued take off and immediately after lift off the shimmy ceased and ride was smooth. Called back to tower above 10;000 ft said to check runway possible tire issue. They responded that there was rubber on runway. Suspected blown tire the crew discussed what was felt and heard. Capt had phone patch to dispatch and maintenance and discussed landing options. All were in aggregated that there was no immediate concern and being overweight for landing that we could safely continue to [the destination]. We ran preparations for egress with flight attendants and pilot checklists. [Advised ATC]. All coordination with [our destination] was complete enroute and there were no surprises at landing. A brace brace brace was used at 200 ft just prior to landing. With a remain seated remain seated as aircraft came to a safe stop on runway. The fire marshal inspected and maintenance confirmed a blown nose wheel tire. We were then hooked up and towed to [the gate]. There was a severe nose wheel shimmy on landing when capt lowered nose wheel and continued until slowed to under 40 kia. The crew was calm and professional. Coordination inside the aircraft and with external agencies was very helpful to plan for landing and then execute the plan without further incident.
