We fly out on Wednesday for the tour which includes matches against champions Orlando Pirates on Saturday July 26 and Kaizer Chiefs on Tuesday July 29.
Gary, the former Manchester United goalkeeper, is now the number one football pundit in South Africa and the face of SuperSport, the country's equivalent of Sky Sports.
He explained: "There is a huge following for the English Premiership here. We get every game live, two matches on a Saturday, Sunday, Monday, FA Cup, League Cup, Champions League, everything.
"Spurs will be well-known out here and because of that, people will expect great things of the club.
"The pressure is on Spurs to come out and put on a performance. There will be great expectation."
