The SP Sport Signature is Dunlop's High Performance All-Season radial developed to deliver year-round performance for the drivers of sport cars, sporty coupes and performance sedans. The SP Sport Signature is designed to blend treadwear, handling and traction on dry and wet roads, as well as in light snow.
The SP Sport Signature molds a high-performance, all-season tread compound into an asymmetric design that has an outboard Dry Performance Sector that features a broad shoulder rib along with notched intermediate and center ribs to enhance steering response and cornering stability. The tire's inboard Wet Performance Sector has an intermediate rib that features Dunlop's Hydro-Paddle Technology combined with independent shoulder blocks that pump water to resist hydroplaning and enhance wet weather traction. Straight sipes that angle across the entire footprint add biting edges to increase wintry traction while maintaining a relatively solid, stable surface. The tire's internal structure includes twin, high-density steel belts reinforced by Dunlop's JointLess Band (JLB) nylon to improve driving control and promote even treadwear while minimizing weight and enhancing ride quality. Hard rubber sidewall reinforcements and a high body ply turn-up enhance steering response and cornering stability.
