The tire has an equatorial plane, an annular tread, and an annular elastomeric body having first and second spaced lateral sides equidistant from the equatorial plane and extending between the tread and the rim. The tire body has a plurality of equally spaced arches forming at least a first series of openings extending from the first side to the second side. The first openings having a height at least one-half the height of the tire side.
