Mga sir, ang engot ko

Did I damage the car/rims/tires? Not sure how long I've been driving it malambot. The steering became stiff today on my way to BGC. Left the car parked for about 10 hrs, going home I noticed that the front left tire looked malambot. I decided to drive it home because imo it didn't look that bad. I'll have it inflated at the gas station near my house. Drove EDSA for 60-80 kph and didn't feel anything different in the steering since I was just driving straight. I did not hear any kalampag too. When I got to Shell, the air in the front left tire was only 13 na dapat 30. The rest of the tires were at 29 so it looks like napako or something yung front left tire.

Does casa repair tires or is there any place in BGC that can repair tires?
