WIDE-BASE SINGLE TIRE
Yokohama Tire has introduced the RY407 wide-base single trailer tire and has its prototype 702 drive tire on display this week at the Mid America Trucking Show. The wide single has just been named a ‘SmartWay’ tire by the EPA.
The RY407, size 445/50R22.5, is said to offer “excellent” fuel efficiency by way of new, high-tech compounds, as well as weight savings potential. Features include better durability and less casing fatigue thanks to an advanced profile, Yokohama claims. There’s also a zero-degree mid-belt that’s said to distribute the load evenly while decreasing running distortion and providing a more consistent footprint. Straight grooves are said to enhance wet traction and cross sipes promote wear resistance.
The prototype 702, which uses Yokohama’s ‘Zenvironment’ technology, promises fuel efficiency and improved wet traction. Available in early 2012 in 295/75R22.5 and 11R22.5 sizes, it’s said to look more like a brawny steer tire than a drive tire.
