Abstract: A hand-held tire pressure and tire soundness testing device is described. A shaft having a linear axis of symmetry, a predetermined maximum shaft cross-sectional dimension, a distal end and a proximal end is provided. A tire-striking head extends from the distal end of the shaft. The tire-striking head has a circular cross-sectional shape perpendicular to the axis of symmetry of the shaft and has an axially symmetrical striking surface defined by rotating an imaginary convex curve around the axis of symmetry at a predetermined maximum head diameter greater than the predetermined maximum shaft diameter. A handle coaxially extends from the proximal end of the shaft. The handle has a circular cross-sectional shape at a plane perpendicular to the axis of symmetry and has a maximum handle diameter equal to or greater than the cross-sectional dimension of the shaft.
