Tevez looked certain to be heading for the exit at the Etihad Stadium in the summer after signalling his desire to leave so he could spend more time with his family.
But when moves to Italian giants Inter Milan and his former club Corinthians fell through and Tevez was stripped of the captaincy, many envisaged a difficult time for the Argentina international.
Back in the fold: Tevez has put the summer distractions behind him
But Hart has heaped praise on the club's top goal scorer last season, saying the diminutive forward remains a positive force within the squad.
'There's a lot of respect for Carlos because he's a great guy and a great footballer,' Hart told BBC Football Focus.
'You wake up and read one thing about him but in training he's really committed to what he's doing.'
Good company: City have continued to make big signings
And the England keeper added: 'He's never disrespected the club in any kind of way or disrespected us as team-mates. He's got on with it.'
City boss Roberto Mancini made a number of high-profile signings in the summer with Sergio Aguero and Samir Nasri joining the club's already world-class line-up for a combined ?62million.
Hart of the matter: The keeper is happy with life at City
But Hart insists there is no class of egos and the dressing room harmony has not been unbalanced by the addition of such stars.
'We've got some of the world's best footballers at this club but they're no different to us,' he said.
'We've got a great set of lads here - no one makes you feel you shouldn't be here and that's what's good about this place at the moment,' added the 24-year-old.
And the former Shrewsbury stopper makes no secret of the club's intentions to match the world's best side Barcelona and in doing so manage a feat their rivals at Old Trafford have failed.
'I think that's ultimately the goal. I'm not going to lie about it. I don't think Manchester United really come into the reckoning. That's not really what we're about, we're not about beating one club,' he said.
'We've a got a lot of respect for Manchester United across the road, doing what they're doing. But ultimately we want to remove everyone in our way to be the best club that we can.'?My medical staff are brilliant! Fergie blasts back at Hargreaves 'guinea pig' claimsNow for England!
