As a tyre rotates under load, thousands and thousands of times, the demands on the casing steel and rubber compounds are incredibly stressful. This strain energy can take the life out of tyres, prematurely. Built into our newest generation of radial truck tyres, our STEM-2 technology brings you more durability than you’ve ever experienced.

STEM-2 redirects normally destructive straining and flexing forces to deliver extended performance to the life of every STEM-2 enhanced Yokohama steel radial tyre.

To help explain this concept, consider the simple paper clip. The rapid bending of a paper clip is an exaggerated view of what the steel belts of a tyre casing go through over the many miles of its life. Over time, the strain of stress loads, heat, road bumps and everyday operation can break down the strength of the steel and the rubber to reduce the life of the average casing.

But Yokohama’s exclusive STEM-2 technology reinforces the casing to make it stand up to these strains, allowing multiple retreads, deeper tread depths and even wider treads. It all adds up to less maintenance costs and more miles for every tyre dollar spent. It’s just what today’s truckers need.
