The Truckers Tire Thumper is an essential tool for truck drivers, serving not only as a tire knocker but also as a fish bat, commonly referred to as a fishing priest. This tire thumper is crafted from solid mahogany wood, measuring 18 inches in length, and features a non-slip grooved handle along with a leather lanyard for easy carrying. The tire thumper allows you to quickly assess whether your big rig's tires are properly inflated by producing a distinct thumping sound upon contact with the rubber. To use the tire thumper, simply swing it onto the surface of the truck tires and listen for the sound it makes. If a tire is underinflated, it will emit a different sound, indicating the need for a safety check with a tire gauge and subsequent inflation.
