Narrative:

At liftoff, aircraft vibrated significantly and I thought wings may have iced up despite going through deicing. I climbed out gently and cleaned up when I was sure we were flying safely. At this point, I thought it was an ice problem so we continued on to our destination as the aircraft was flying ok in clear air above the icing conditions. En route, the copilot pointed out that the previous crew had used maximum autobrakes and perhaps we had a damaged tire. Considering this, I made a soft landing at our destination using little or no brakes. Vibration during rollout and taxi in confirmed the copilot's suspicions. Postflt showed a large chunk of cap missing from #2 main, but tire was holding pressure.

Title: A FLT CREW NOTICE A SIGNIFICANT VIBRATION ON LIFTOFF. THEY SUSPECT ICE BUT IT TURNED OUT TO BE A DAMAGED TIRE.

Narrative: AT LIFTOFF, ACFT VIBRATED SIGNIFICANTLY AND I THOUGHT WINGS MAY HAVE ICED UP DESPITE GOING THROUGH DEICING. I CLBED OUT GENTLY AND CLEANED UP WHEN I WAS SURE WE WERE FLYING SAFELY. AT THIS POINT, I THOUGHT IT WAS AN ICE PROB SO WE CONTINUED ON TO OUR DEST AS THE ACFT WAS FLYING OK IN CLR AIR ABOVE THE ICING CONDITIONS.
