Got a flat tire last week cause by 3 nail punctures. 2 nails were still lodged in the tire but somehow the 3rd came out on it's own. I also broke a stud when trying to put the spare on too. I plugged up all 3 holes myself but yesterday I notice the tire was still losing air. Had a tire shop by my work place check it out and damn it, one of the nails went through and punctured the sidewall too. Just a pin size hole right above the bead. Shop wants $150 for new tire mounted and balanced. Tire still has a good 80-85% tread left too.
