Narrative:

On take off; at V1; we felt a severe yaw to the right. There were no EICAS messages in association with this event or engine indications that were not normal. However; it was enough for us to consider that we might have had a problem with a blown tire. We asked ATC to check the runway for debris. They reported back that there was none. This; however; did not mean that we did not have a problem. It was enough that the flight attendants asked about the yaw. I discussed the situation with my first officer and we both found it prudent to declare an emergency when were inbound to destination. This ensured that the crash fire rescue equipment would be ready in case anything was truly wrong. We landed without incident.
