i recently popped one of my tires and it can't be repaired. i still have plenty of thread on my other tires so i don't need new tires for all 4, but i don't want to buy a brand new tire for the popped one. where can i get a used tire thats in pretty good condition that has a good amount of thread and won't cost me a lot of money? i don't want to pay too much for a used tire and it ends up popping on the same day that i get it. please help me out!
