The Argentine believes that his compatriot's arrival in Turin has ensured that the Bianconeri will once again be "a step ahead of the rest" this term
The Bianconeri lifted their second successive Scudetto back in May and have now bolstered their attack with the additions of Tevez and Fernando Llorente.
Consequently, Palacio feels that Juve will again be the team to beat this year, particularly in light of his fellow Argentine's arrival in Turin.
"Tevez is a great striker who has made a difference in every league in which he has played," the 31-year-old attacker told Corriere dello Sport. "For me, he will play a leading role this season.
"For the Scudetto, Juventus is still a step ahead of the rest."
However, Palacio remains confident Inter can have a strong season under new boss Walter Mazzarri, despite their struggles last season.
"I have never struggled so much in pre-season - he works us so much," the former Genoa striker enthused.
"I really like how he operates. He is a coach with a lot of experience who has clear ideas and places a lot of emphasis on dialogue with the players.
"However, at this time, we should not be thinking about the Scudetto, but one game at a time.
"We have a good team - I am convinced of this - and it is necessary to do their utmost to try to win all the time.
"The important thing is to work and give everything. The results will come. Our first objective, though, is to fight to be as high as possible [in the table]."
Despite his obvious satisifaction with Mazzarri's methods, Palacio freely admits that he was sad to see Andrea Stramaccioni sacked at the end of last season.
"I felt sorry for him over his dismissal," he admitted. "I had a good relationship with him.
"He helped me and gave me confidence. Unfortunately, in football, when the results do not come, the coach pays."
Even though Inter limped home in ninth place, Palacio enjoyed a terrific season under Stramaccioni and is more than content to still be at San Siro.
"I have not received any transfer offers but it's better like this," he explained. "I'm happy at Inter. I'm convinced that I can win here."
Palacio, who arrived at Appiano Gentile from Genoa last summer, netted 22 times in 38 appearances in all competitions.
