Interesting: Since they tried to run him down with their vehicle, their crime turned into a felony. That makes him discharging his weapon legal

So I wonder, if he just fired at their tires if they didn't try to run him down, would he have committed a crime?

Texas law states that if you are in fear of your life, you are justified in using deadly force. If this car was trying to run him down, he could have shot the driver. But everytime you discharge your weapon, you will come under law enforcement scrutiny, so you have to take that decision very seriously. Conceal carry is for that purpose.
