The 33-year-old was expected to play second fiddle to Froome for three weeks in France this year.
But Wiggins is adamant he will aim to defend his crown, once he has secured the first half of an incredible double in Italy.
“The Tour de France is my focus, it’s just that I’m doing the Giro before,” he said. “There’s been a lot of talk about [supporting Froome] but it’s for the team management to decide.
“We are both on different paths and are both professionals. We have been there before. We’re on the same team and we know what needs to be done.
“I would be comfortable in a supporting role but it’s not like I’m going to ride 200km on the front and swing off and lose 30 minutes. I want to be there at the death, I want to be on the podium.”
