Got new tires put on in the fall. Went to put air in them to top them off and one of the tires won’t accept air. Is this just the valve core issue where I can take that needle out or do I need to take it to the shop and get an all new valve stem? I aired up the other tires just fine so I doubt it’s my air chuck. It’s at 28 lbs when should be 33. Also is the valve core vehicle speciffic?
