This essential tool for truckers is an 18-inch wooden tire thumper checker that lets you know if your big rig truck tires are fully pressurized by making a thumping sound as it hits the rubber. Just swing the wooden tire thumper checker on top of the big rig truck tires and listen to the sound. If one of your tires is at a lower pressure, it will make a different sound and should be checked with a tire gauge for safety and filled. A wooden tire thumper or tire knocker can help you save time when checking tire pressure on your big rig. The tire thumper is made of solid mahogany wood with a non-slip groove handle and comes with a leather lanyard.
