Dunlop Sportmax Roadsmart IV Rear Tire 190/55ZR17 (75W) Blackwall Sport Touring Motorcycle Tire

OVERVIEW

The Dunlop Sportmax Roadsmart IV rear tire delivers dependable traction and extended durability for sport-touring motorcycles requiring a radial tubeless construction. Built with reinforced rubber compounds and a precise multi-tread layout, this straight-section tire supports sustained highway cruising while providing stable cornering grip. It is engineered specifically for modern sport-touring platforms that demand consistent feedback without sacrificing tread life.

ENGINEERING & PERFORMANCE

The Hi Silica X compound increases silica concentration in the tread formula to maintain predictable adhesion across both wet and dry pavement surfaces. Radial casing geometry works alongside a three-component tire makeup to accelerate warm-up cycles and preserve consistent air pressure during repeated street riding sessions. This architecture ensures progressive weight transfer into the shoulder zones while the center tread maintains high-mileage stability under loaded touring conditions.

WHY RIDERS CHOOSE THIS

Riders prefer this rear tire because its balanced tread architecture extends service life while maintaining progressive cornering stability on long-distance routes. The silica-enhanced compound and radial casing deliver consistent grip across changing pavement conditions, eliminating the need for extensive break-in periods before full performance recovery. Faster warm-up cycles paired with a rigid yet responsive sidewall structure keep pressure uniform during spirited street riding or heavy luggage loads. This setup aligns directly with the handling expectations of modern sport-touring platforms, offering reliable feedback from front to rear without compromising longevity.
