Falken RI121 Sa
The Falken RI121 Sa is a medium-duty commercial trailer tire built for one specific job: surviving spread axle trailers that beat up tires with brutal lateral stress. This isn't a jack-of-all-trades tire, it's a specialist made to fight the sideways scrubbing that chews up ordinary trailer rubber. If feather edging and rib erosion have been ruining your tread life, this is the tire that was designed to fix that headache.

Benefits
Fights feather edge wear and rib erosion caused by high lateral forces, keeping wear even and mileage up. Absorbs tread distortion better to cut down shoulder erosion, so spread axle trailer positions get longer, more predictable tread life.
