A tractor tire is disclosed having widely spaced lug pairs with a symmetrical Y-shaped footprint, each lug pair having inclined transverse lugs and an elongated longitudinal nose portion at the peripheral centerline providing a central lug projecting in the direction of tire rotation and overlapping the trailing end portions of the next adjacent lug pair. The unique lug arrangement minimizes vibration to improve safety during operation on the highway while retaining the characteristics required for effective off-the-road (OTR) performance on soft ground.

A pneumatic tire for tractors and other off-the-road vehicles having a tread comprising a series of y-shaped lug pairs spaced around the periphery of the tire comprising transverse alternating long and short lugs at each side of the peripheral centerline of the tire, each of said transverse lugs having a length at least several times its width, is spaced from the transverse lugs of the next adjacent lug pair a distance at least several times its width and extends inwardly from the outer sides of the tread inclined at substantially the same angle of between 40°to 60°relative to said centerline, each of said long lug having a longitudinal nose portion extending, in the intended direction of rotation of the tire, along and disposed substantially symmetrical with respect to said centerline, each of said nose portions overlapping the trailing end of the next adjacent lug pair to receive the load as it is transferred from said end portions, and being spaced from the nose portion of the next adjacent lug pair to provide an earth-receiving recess therebetween and such that said nose portions of all of said long lugs collectively occupy no more than about half the circumference of the tread along said centerline.
