McIntyre subsequently joined the Tipperary senior inter-county team, making his championship debut in a Munster quarter-final against Clare in 1983. It was a n uncharacteristic lean period for Tipp. In his second season McIntyre lined out in his first Munster final. Cork provided the opposition and were going for a third provincial title in succession. Tipperary were hoping to win their first since 1971. With four minutes remaining Tipperary led by four points and the hoodoo looked set to end. Cork's Seánie O'Leary and Tony O'Sullivan had a different idea. Two quick goals clinched a 4–15 to 3–14 victory and McIntyre's side were defeated once again. In 1985 Tipperary and Cork went to battle in the Munster decider once again. On this occasion there was no nail-biting finish as Cork secured a 4–17 to 4–11 victory and McIntyre found himself on the losing side for the second time. By 1986 McIntyre was relegated to the substitutes' bench and was replaced at centre-back by Noel Sheehy. He came on as a replacement in Tipp's Munster semi-final defeat by Clare. This was his last game with Tipperary. In 2001 McIntyre was recruited to the Clarinbridge senior hurling team as coach. It was a successful year for the club, as Clarinbridge reached the final of the county senior championship. Reigning All-Ireland club champions Athenry provided the opposition and were the favourites going into the game. Former Galway star Darragh Coen scored a point from a disputed free deep into injury time to secure a deserved 0–18 to 2–11 victory for McIntyre's side. It was Calrinbridge's first county title. The club subsequently reached the Connacht club final. Four Roads of Roscommon provided the opposition, however, Clarinbridge were too strong and won the game by 2–18 to 1–6. McIntyre's side later defeated Ballygunner in the All-Ireland semi-final to set up a championship decider meeting with Birr. That game at Semple Stadium saw Birr take complete control and defeat Clarinbridge by 2–10 to 1–5. In late 1996 McIntyre became involved in inter-county management for the first time when he took charge of the Offaly senior team. His term in charge was not a successful one. After an average National League campaign Offaly subsequently had an unlucky Leinster semi-final defeat by Wexford.
