Narrative:

Captain was pilot flying. We departed the gate; completed appropriate checklists and procedures as normal; taxied to the runway and at the time we were number 3 for departure. After being cleared for takeoff; we took the runway and completed before takeoff check. Aircraft accelerated normally; made the 80 knot callout; V1 callout 5 knots prior to V1 as we are trained. Right at V1 we heard a large 'boom' from the rear of the aircraft; nose of aircraft pitched down and to the right. Captain retarded the throttles; deployed reversers; and extended flight spoilers while trying to return the aircraft to the runway centerline and stop the aircraft as quickly as possible. I (pilot monitoring) told ATC we were aborting; made my standard call outs (spoilers; two reverse; 90 knots; etc.). Captain was able to slow the aircraft down and make turnoff [near the end of the 10;000 foot runway]. ATC was asking questions as we taxied off; I told them to standby as we dealt with rejected takeoff. Captain set the parking brake and we analyzed the situation (completed rejected takeoff checklist). We agreed it was most likely a blown tire on the right side of the aircraft. I wanted to get out and check to make sure the brakes were not on fire in case we needed to evacuate the passengers. Captain agreed and I opened the cabin door for a visual inspection. I noticed that the outboard wheel was smoking slightly; but at the time it didn't appear to be getting worse or notice any fire. Captain worked the radios coordinated with ATC; maintenance; and operations to get the passengers back to the terminal and the aircraft off the taxiway. Operations and fire rescue arrived; fire team agreed that the wheel did not pose a threat and we waited for buses to arrive to deplane the passengers. We stayed with maintenance for a short while; contacted the chief pilot; and dispatch; then drove back to the terminal in airport operations truck. I still have no idea why the tires blew. They were completely shredded once we got off the aircraft. I had been doing walk arounds on that aircraft for almost two days and remember the inboard main tire looking fairly new. Both were in good condition the previous 3 flights we did in that aircraft.
