While glancing at my spouse's car tires, I noticed a nail in the front left tire. Seems like air doesn't come out of that tire. I then took a look at all tires and saw that the 2 front tires have holes expansion / tears (picture added below).
All of the tires are the same model of "Falken" brand and were bought around 3 years ago.
Should I: just fix the front left tire / replace 2 front tires / replace all tires ? What might have caused the holes expansion / tears in the front tires? If it's something in the car, maybe I should fix it.
