Big men drive BIG TRUCKS ... at least Tyson Chandler does -- and TMZ Sports has footage of the 7'1" NBA star hittin' the road in a tricked out "baby monster truck."
The New York Knicks center was out in Calabasas this week in what appears to be a lifted 2010 Ford F350 Super Duty … a car that just DOMINATES on the road.
Chandler says he likes the truck because at his size, he fits pretty comfortably in it -- and only goes off-roading in his diesel vehicle "if a car gets in my way."
FYI -- maintaining that truck ain't cheap, the tank holds 38 gallons of diesel gas ... which currently runs $3.99 per gallon in Calabasas ... so, you're talkin' a cool $150 per tank.
Good thing he's rich.
