I found a screw(3/8 inch) in my tire today. It was stuck in the thread block(the thickest part) of my left passenger tire. I pulled it out and there isn't any leaks. So should I take it in have it patch just in case or leave it as it is?
Put some water over the area where the screw entered the tread. If you don't see bubbles, then the tire is not leaking and no further action is necessary. As they say, don't fix what isn't broken.
