<p>A power transmission belt (10) has a body (12) with a length (L), a width (W), an inside (18) and an outside (20). The body (12) has at least one load carrying member (22) embedded in rubber and extending in a lengthwise direction. The body (12) defines a plurality of teeth (28) spaced along the length of the belt on at least one of the inside and outside of the body. At least one of: (a) the at least one load carrying member (22) has an occupying rate (R) that is not less than 75%, with R = n x Dc/B x 100 where: n = number of load carrying members (22) aligned along the width of the body; Dc = diameter of load carrying member(s); and B = width of the body; and (b) the at least one load carrying member has a cross-sectional area taken transversely to the length of the body that is in a range of 1.10 to 1.70 mm2 per 1mm of belt width.
