This 18-inch stained and sealed solid wood tire thumper lets you know if your tires are fully pressurized by making a thump as it hits the rubber. Just swing the thumper and listen for the sound. If your tires are low in pressure it makes a different sound. Features a weighted end with metal bolt and a nylon cord for hanging. Measures 18.5 inch length x 1.25 inch diameter. Made of strong and durable natural wood. An ideal choice for a trucking accessory that will be subjected to frequent use and possibly harsh conditions. It can withstand heavy impact and resist deformation to ensure your tire striker remains reliable and functional over time. The stained wood is an especially attractive design and the well balanced weight of this night stick style thumper enables the trained ear to check air pressure in tires by sound and lets you feel for the proper bounce to judge proper tire inflation. Get back on the road in no time. Another great innovation from RoadPro your trusted travel companion, bringing the comforts of home to on-the-go living.
