LeBron James' Taco Tuesday tradition is making a big impact this week ... the Lakers superstar sent food trucks to the firefighters and first responders working to put an end to the California wildfires.
LBJ -- who was forced to evacuate his Brentwood mansion when fires got dangerously close to his home -- sent his thanks to the people battling the blazes with delicious tacos.
L.A. mayor Eric Garcetti thanked Bron for the gesture ... saying "Thank you, @KingJames, for generously sending a taco truck to support our @LAFD firefighters, first responders, and partner agencies working to fight the #GettyFire.
