Abstract
An improved nonpneumatic tire for a motor vehicle is described. The tire has a rim and one or more elastomeric materials bonded to the rim or to one another. The tire has an equatorial plane, an annular tread rotatable about an axis, and an annular elastomeric body. The elastomeric body has at least 48 openings, a first set of at least 24 openings extend from the first side and a second set of at least 24 openings extend from a second side, both sets extending toward the equatorial plane. The openings form equally spaced columns. The columns formed by the first set of openings are inclined to the radial direction. The columns formed by the second set of openings are inclined opposite to the columns of the first set. The improved tire is characterized by columns having cross sections equidistant from the equatorial plane. The cross section of each of the columns increases in thickness from a minimum to maximums at the radially inner and radially outer extremes of the column.
