The Alliance 403 is a specialized radial steering tyre featuring a classic multi-rib profile. In this size, the PROFILE follows the standard narrow tractor steering ratio, providing a tall sidewall that facilitates high ground clearance for the front axle. Standing at approximately 805 mm tall, the 403 provides a stable “track” for the tractor to follow, which is essential for row-crop weeding and seeding tasks. The radial internal structure allows for a slight “flex,” which helps absorb vibrations before they reach the steering wheel, improving operator comfort during long hours in the field.
