Robot does not have enough torque to turn motors at low PWM values

I am currently trying to implement the differential_drive package. I simply cannot tune the parameters to get suitable control. The motors often hum instead of turn. If I use high gains (to overcome low PWM values fast enough) with the controller I get very oscillatory motion.

Has anybody faced the same problem. I desperately need help.
