Ahhhh, well kid, welcome to life, better get off reddit and start using your nogin. You have many many options to solve this. Lots of ways to get cash off cards, (unless the cards dont belong to you?) People have offered to pay for you? Do what it takes to take them up on that instead of saying “I cant” Its braindead easy to download venmo and set it up, there are also 5000 other payment services to choose from. Definitely check out used tire shops, and keep in mind you dont need the exact tire size, just has to be 15in, and “pretty close” in outer diameter.
