Abstract: A pneumatic tire, which may be used as a control tire for calibrating tire testing equipment, comprises a pair of annular beads (40), at least one carcass ply (15) wrapped around the beads, belt reinforcement (13,14,16) disposed over the at least one carcass ply in a crown area of the tire, a tread (12) disposed over the belt reinforcement, and sidewalls (18) disposed between the tread (12) and the beads (40), The tire is made with a tread (12) having no grooves or sipes, and which comprises a radial medium truck tire retreading compound. The belt reinforcement (17,17a,17b ) is laid up in the circumference of the tire with a low angle, i.e. less than 0.75° with respect to the EP of the tire in the second belt (14), and less than 0.5° with respect to the EP of the tire in the first belt (13,16).
