I found a nail in my Corolla's Pirellis when putting on my studded snow tires. Ima take them to Autozone or whatever is close, they'll use a method to see if theres any leaks and seal the leaks off. Make sure they seal it off properly though. My brother bought Tires from Autozone so he had warranty and they fixed the tire for free. However, he checked the tire after they sealed it and he said check it again and it was still slightly leaking. So they tried sealing it again and it worked.
