Is it OK to drive with a screw in your tire?
That’s not good for a couple of reasons: 1.) Your tire could blow out, and 2.) if the hole continues to grow, you run the risk of ruining the tire altogether.
Why is my tire deflating with no hole?
Valve Stem Leak
Flat tires aren’t always caused by a hole in the rubber. Instead, a malfunction or leak in the valve stem can be the culprit. The valve stem is the part of the tire that you unscrew when adding air. Any damage or even dirt on this small piece could cause your tire to lose air until it’s completely flat.
