Interlocking 3D siping used in Avon’s new Ultra Xtreme, Supersport and Sport radials was developed by parent company Cooper Tire for winter car tires. On two wheels, the intent is improved tread-block stability in wet and dry conditions, leading to a larger footprint and improved grip at deep lean angles. The Ultra Xtreme and Ultra Supersport models share the same sticky race compound; Ultra Supersport and Ultra Sport (shown) have the same tread pattern and more prominent siping. Sport uses a Triple Extrusion compound—more durable in the center, softer on the sides. A third compound located under the first two binds them together, reducing tire temperature and increasing tread life. The 3D Ultra Supersport and Ultra Sport come with a limited road-hazard warranty. Per-pair MSRP ranges from $408.71 to $525.49.
