Narrative:

During the takeoff roll we experienced an itt (interstage turbine temperature) exceedance due to compressor stall and aborted the takeoff. We returned to the gate with no further complications. The previous takeoff was also aborted due to a shudder down the right side of the aircraft; which we thought was a blown tire. We did not notice any abnormal engine indications. We returned to the gate after the first abort to check for damage. No damage was noted and maintenance and dispatch were notified. From my description of the event; maintenance control felt we had a nose wheel shimmy. Contract maintenance was dispatched and discovered a missing fitting on the nose gear suspension and that the nose gear needed lubricant. I accepted that as the correct repair and we tried again. On the second attempted takeoff I noticed the itt approach the redline; then a series of rapid bangs. The itt dropped some and as I started to abort the takeoff the itt shot up into the red. I had never experienced a compressor stall before and I thought the nose resembled a blown tire. Greater emphasis and education on the sensations associated with compressor would have been helpful and lead to a more accurate initial call to maintenance.

Title: ERJ-175 flight crew reported rejecting two takeoff attempts. The first was for a suspected blown tire and the second for ITT exceedance and compressor stall.
