Changed plenty, but I also I keep a a repair kit in my truck and have had luck being able to find and plug the hole and then plug the small air pump into the cig. lighter to get enough air to get going on my way.

Having your own air pump is essential when you surf fish and need to lower your pressure to drive on the beach in some areas. It is required to have an air pump, shovel, boards, jack etc... to fish Island Beach State Park in New Jersey. So the having the air pump comes in handy.
