The build-up to the new Guinness Premiership season also features four away fixtures, including short trips to Bedford and Nottingham.
"We probably have more games this year in the pre-season programme but that is because we have a lot of guys away on international duty and a lot of new faces in the squad," Richard Cockerill, Tigers' acting head coach, said.
"There is a lot of work to do on new combinations in the team and on organisation, so we have a number of games organised before the league starts. They are all there to build up to the start of the Guinness Premiership season."
Tigers begin with a trip to the South-West to face Cornish Pirates on Saturday, August 4, and follow with games at Bedford and Nottingham on successive weekends.
There is also a fixture away to Bayonne in south-west France on September 1 before the home match against Montauban.
Last season it was Toulon who travelled across the Channel for Tigers' pre-season fixture, with Tigers winning 39-19 at Welford Road.
Montauban finished seventh in the French Top-14 last season and will compete in the European Challenge Cup in 2007/08.
Ticket details for the Montauban fixture will be revealed on the Tigers official club website soon.
Tigers' pre-season programme:
