Firestone RIB Duplex Farm I-1 Tires

Product Info

RIB Duplex Farm I-1

Firestone’s Firestone RIB Duplex Farm I-1 tires are a specialty agricultural implement option for exact-size replacement on field equipment. Gunnell's Tire & Auto can help shoppers match this model to the right application when the equipment calls for a ribbed, flotation-style fitment.

This model is cataloged in one size: 36x16-17.5, with Load Range D construction and part number 318-523. That makes size and rim verification especially important before ordering, especially for farm implements and other agricultural equipment that need stable tracking and practical field mobility.

If you’re replacing a worn implement tire by size or part number, this Firestone option is built around the needs of specialty farm use rather than highway driving. Visit Gunnell's Tire & Auto to review your fitment details, or start with Firestone tires to explore more from the brand.
