Introducing the all-new Sportmax Q4. Bold look, bold performance for bold riders.

Sportmax Q4
A purpose-built track-day tire achieves lean angles up to 62 degrees! More than any other street-legal tire Dunlop has ever made.

FEATURES

  • The user-friendly Q4 does not require tire warmers, and runs at street pressures, eliminating the need for chassis or electronic adjustments.
  • Rear tire compound contains carbon black like Dunlop’s racing slicks for maximum grip.
  • Jointless Tread (JLT) technology uses a continuously wound strip compound to optimize stability, flex, and grip across the rear tread profile.
  • Carbon Fiber Technology (CFT) uses carbon fiber reinforcement in the sidewalls for exceptional cornering performance, braking stability and feel.
  • On Tread Branding—raised letters built into the sidewall.
  • This purpose-built track-day tire achieves lean angles up to 62 degrees*, more than any other street-legal tire Dunlop has ever made.
  • Made in the U.S.A. Only Dunlop makes sport tires in America.
