My car has blown 2 tires in the past month and I don’t have money to replace the others.

Hello, I am a full time student who is in an internship and a part time job trying to make ends meet. I drive a lot, for school, work, and my internship. Over the past month, I’ve had 2 tires blow out because I haven’t had money to get new ones. I’m afraid my other 2 will blow out soon. I’ve had these tires for 4+ years and every tire shop I’ve gone to says they were meant to be replaced at least a year ago. I could barely afford the first 2 tires. I bought them already used because that’s all I could afford. Im worried because if the next one blows, I won’t have enough money to cover it. I’m requesting any amount of money to help with this. I would really appreciate any amount. I’ve never asked for money before but I’m really in a bind. As I said before, I’d really be grateful for any amount to help get some new tires. I appreciate anyone taking the time to read this, thank you for listening.
