TIRE INFO
The Toyo Extensa HP II 315/35R17 is an ultra-high-performance all-season tire designed for drivers who want a wide footprint, responsive handling, and a sporty appearance. Its 315 mm section width provides a broad contact patch, while the low 35-series sidewall gives the tire a performance-oriented profile.
Designed for sports cars, performance coupes, and suitable custom applications, it combines everyday usability with handling characteristics suited to spirited street driving.
One of the tire's key features is its directional tread design, engineered to help provide traction in dry and wet conditions. The tread pattern incorporates variable-pitch elements intended to help manage road noise, while specialized tread-block tapers are designed to improve braking performance by optimizing block stiffness. Together, these features aim to deliver predictable steering response, stable cornering, and confident road manners.
The Extensa HP II is also designed to balance performance with ride comfort. Its all-season tread compound and groove arrangement help evacuate water from beneath the tire, supporting wet-road traction and reducing the risk of hydroplaning. With a 102 load index, each tire is rated to carry up to 1,874 pounds under specified conditions. Its W speed rating indicates a maximum rated speed of 168 mph under applicable conditions.
The 315/35R17 size has an approximate overall diameter of 25.7 inches and is approved for rim widths between 10.5 and 12.5 inches. Its wide profile makes it particularly appealing for performance builds that require substantial rear-tire width. Before installation, confirm the wheel width, suspension clearance, and vehicle-specific fitment. The tire's directional tread also means it must be mounted in the correct rotational direction.
Overall, the Toyo Extensa HP II is a strong option for drivers seeking a wide performance tire with all-season versatility, responsive handling, and a 45,000-mile treadwear warranty. Regular tire rotations where fitment allows, correct inflation, and proper wheel alignment can help maintain even tread wear and consistent performance throughout its service life.
