A pneumatic tire for agricultural equipment or forestry equipment includes a circumferential tread, a pair of sidewalls, and a pair of bead portions. A steel reinforced radial carcass ply extends circumferentially about the tire. The carcass ply includes an axially inner portion and axially outer turn-up portions. First and second steel reinforced belts are disposed between the carcass ply and the circumferential tread. Axial ends of the belts are separated by belt wedges. The tire includes a pair of sidewall inserts. Each sidewall insert extends continuously from an upper end extending between the first belt and the carcass ply, through a sidewall region of the tire, to a lower end extending between the inner portion of the carcass ply and one of the turn-up portions of the carcass ply. A tie gum layer binds an inner liner to the carcass ply.
