Yokahama had a preview version of the RY407 on display last year at MATS.
"Now it's in production and available in limited quantity. It's also just been named a 'SmartWay' tire by the EPA, meaning it's recognized as a low rolling resistance tire," said Rick Phillips, Yokohama's director of commercial sales.
The RY407 super single, size 445/50R22.5, offers fuel efficiency as well as a weight savings potential for fleets, said Phillips.
"There's less weight because there's one tire and wheel assembly instead of two. And because of its unique design and construction we expect the RY407 to be a very durable and retreadable product."
Highlights of the ultra-wide tread RY407 are:
* Better durability and less casing fatigue thanks to an advanced profile.
* New, high-tech compounds for improved fuel efficiency.
* A zero-degree mid-belt that distributes the load evenly, lessens running distortion and has a more consistent footprint.
* Straight grooves for enhanced wet traction and cross sipes for wear resistance.
The 702 will be available in the U.S. in early 2012 in 295/75R22.5 and 11R22.5.
Highlights of the 702 are:
* Low rolling resistance and superior fuel economy, thanks to the new compound using Zenvironment technology.
* Unique drive tire tread design.
* Solid shoulder rib and serpentine grooves for extra rigidity and stability.
* Yokohama's patented Stress Control Groove that redistributes the shoulder load to prevent step down wear.
* Z Block design to improve wet traction and lower rolling resistance.
