A lubricating system indirectly applies a bladder release agent to a green tire and cures the green tire in a tire curing machine. The system includes a deposition device and a curing bladder. The deposition device directly applies bladder release agent on to a deposition bladder. The deposition bladder is inflated within the green tire in order to deposit the bladder release agent on to an inner surface of the green tire. The curing bladder subsequently receives the green tire with bladder release agent deposited therein and cures the green tire.

A tire has a circumferential tread, the tread including shoulder tread regions configured for off-road performance separated by and interlocking with a center tread region configured for on-road performance. The shoulder tread regions are defined by a repeating pattern of two or more distinct shoulder tread elements and the center tread region is defined by a repeating pattern of two or more distinct center tread elements. The shoulder tread elements each have a ground contacting surface area greater than a ground contacting surface area of the center tread elements. The center tread elements extend at a relatively greater angle of inclination with respect to an equatorial centerplane of the tire and the shoulder tread elements extend at a relatively lesser angle of inclination with respect to the centerplane. The center tread elements and the shoulder tread elements are irregular and asymmetrical about a longitudinal central axis and a transverse central axis and, together, total five or more (three in the center tread region and two in the shoulder tread region) tread blocks of mutually distinctive geometric shape.
