Toyo Tires Technology
Toyo Tires is a company committed to making maximum use of advanced technology to produce highly evolved, industry leading products. Supercomputer power and the latest technology can be found in the laboratories and in the design areas, as well as on the production floor – with the payoff coming in the outstanding performance of Toyo Tires on the highway.

DSOC II™ Technology
One of the most prominent uses of supercomputer power is in Toyo’s DSOC II (Dynamic Simulation Optimized Contact) technology. By dynamically simulating the extremely complex activities and behavioral characteristics of a tire under a wide variety of running conditions,
DSOC II allows the optimization of many tire attributes. These range from engineering-oriented areas such as durability, stability, wear resistance, rim fit, and rolling resistance, to human-oriented concerns such as ride comfort and noise. DSOC II technology is split into two main areas: STACS and CASPAN.
STACS™
The STACS (STructural Analysis Computer Software) area concentrates on simulating tire response to dynamic forces, such as acceleration, braking, steering, and cornering.
CASPAN™
CASPAN (Computer Aided Simulator for Pattern Noise), on the other hand, examines things such as the shape of the tire’s contact patch and its related pressures, with the goal of reducing tread-generated noise.
The combined results of the STACS and CASPAN disciplines is that Toyo Tires provide responsive, predictable handling and excellent transient stability, all the while delivering a smooth, comfortable ride.
“JOINTLESS” Technology
As good as these compounds are, the fact of the matter is that they wouldn’t be much use without some truly advanced tire-construction technology. Two prime examples of this technology focus on the use of “jointless” techniques.
The first is a “jointless” bead wire package. Rather than multiple layers of side by side wires, a single strand of wire circles the bead area 24 times. It is designed in such a way as to eliminate joints and splices without compromising strength. The result is stable performance at high speed combined with a smooth, comfortable ride.
This strong bead-wire technology is complemented by a jointless edge and cap-ply technique that wraps a continuous strip of nylon cord tape around the circumference of the tire, over the steel belts. This controls expansion of the tire casing and increases strength and stability. The result is improved high-speed endurance. Ride comfort also benefits from the increased uniformity of this type of construction. “Jointless” construction is available in all of Toyo’s ultra-high performance passenger sizes.
THE SILENT WALL
The PROXES ST III along with future Toyo tire models feature grooves designed with thousands of vertical serrations along the tread block wall. These serrations disrupt the sound waves reducing audible noise increasing ride comfort. It all results in an exceptionally smooth, quiet ride, worthy of the finest automobile.
Variable-pitch Tread Design
CASPAN modeling and supercomputer technology pay big dividends in tread design. By using CASPAN’s advanced simulation capabilities to analyze potential tread designs and predict characteristics such as noise generation, Toyo has been able to produce variable-pitch tread designs. They are quiet-riding yet highly responsive in steering, braking, and acceleration, all without compromising ride comfort.
Rim Protector
Toyo Tires is well aware that many cars now come with expensive wheels or are fitted with them through the aftermarket by their owners. To help protect this sizable investment, Toyo Tires molds a special rim protector into the lower sidewall, adjacent to the rim on some sizes. It helps prevent scratches and abrasions to expensive wheels.
Unidirectional Tire Designs
Designed to be mounted and run in one direction, a unidirectional tread appears as a “V” shape. Unidirectional designs optimize water dispersion from under the tread to reduce aquaplaning.
Multi-wave Sipe
Sipes improve wet traction, but they also reduce tread block rigidity. Rigid tread blocks are desirable for better dry handling. Toyo Tires has overcome this inherent design compromise with its new proprietary “Multi-Wave” sipe technology. This design provides tread block support from the sipe walls, which reduces excessive deformation while cornering and braking. Excessive tread block deformation is also what leads to the “heel and toe” wear that causes increased pattern noise as a tire wears. Therefore, “Multi-Wave” sipe design also helps to reduce tire noise.
