Keep your trailer rolling smoothly and safely with the Yokohama 121T trailer tire.
Yokohama 121T Features
Whether your business requires hauling just one commercial trailer or a fleet of many, you probably have safety and performance on your mind. The Yokohama 121T provides both.
This versatile commercial trailer tire performs equally well in long-haul, regional-haul or local pick-up and delivery operations. It’s K-speed rated, so typical highway speeds are no problem.
The tread pattern is designed to provide low rolling resistance to support fuel efficiency, while serpentine grooves and concave lug patterns provide outstanding traction in both dry and wet conditions, including light snow.
Features of the Yokohama 121T include:
Three-groove tread pattern lowers rolling resistance to help increase fuel efficiency
Serpentine grooves help sweep water away from the contact patch to preserve traction in wet or snowy conditions.
Three-peak mountain snowflake (3PMS) rated for proven performance in light snow.
Rigid shoulder design encourages straight-line stability.
Funnel-shaped step grooves help keep stones and debris from reaching the casing.
Yokohama 121T Treadwear & Warranty
This tire is covered by a 6-year casing warranty, as well as the manufacturer’s standard limited warranty for truck/bus tires.
Our Certificates offer the peace of mind that comes from knowing your tires are protected. If you have a tire that’s damaged due to puncture, road hazard or manufacturer’s defect and it can’t be safely repaired, we will replace it at no charge.
You can add our Certificates to your cart!
For reliable performance that never lags behind, choose the Yokohama 121T trailer tire.
