PORTMAX Q5A Challenge to infinite possibilities, "A" title
SPORTMAX Roadsport2 with all-round performance and SPORTMAX Q5 with aggressive pattern design.
The SPORTMAX Q5A is a new product that has been built with all of the latest Japanese technology and surpasses the performance of the SportsTire products that Dunlop has developed to date..
DRY/WETGrip of high dimension, light handling and long life performance provide excellent RidingPleasure..
SPORTMAX Q5A" is a tire in the SportsSegment of the MCRadial product lineup..
The overall performance has been improved from the conventional product "SPORTMAX Roadsport2", and the size lineup has been expanded to a larger size. In addition to the light handling required for sports driving, dry & wet grip has been achieved at a higher dimension..
LongGroove, a direct descendant of SPORTMAX Q5, is used for PatternDesign.. We aimed to create a tire that can meet a wide variety of driving demands..
It is an "All-round SportsTire" that is also suitable for touring and city driving applications by realizing a long life..
*The [A] in SPORTMAX Q5A stands for "All-round.

•Performance
[01]On-board technology
The LongGroovePattern, a direct descendant of the SPORTMAX Q5, provides an aggressive appearance, and is equipped with technology that can cover a wide range of applications from sports to touring..
[02]LongGroovePattern
Aggressive LongGroovePattern.
Pattern placement optimized for Sports driving. Balance of DRY and WET performance.
Uneven Wear Suppression Pattern.
Pattern stiffness near the ground edge is increased.. Handling change after wear progresses in STREET and Touring has been suppressed..
[03] Three-partition MultiPullTread structure
3-division MultiPullTread structure on the front. *Excluding some sizes
Improved response to deep bank angles during sports driving and a sense of security on wet road surfaces..
New Hi SILICA XCompound. (Adoption of high Tg modified polymer)
Silica content is increased to 175% of conventional products by adopting high Tg modified polymer.. Follows the road surface more supplely. Prevents sudden slippage at low temperatures or on WET road surfaces.
Shoulder section with Racing carbonHigh gripCompound.
for Race particulate carbon for improved heat generation and dry grip performance.
Evolved to Rear3-Split MultiPullTread structure.
Adopted 3-division MultiPullTread structure instead of conventional 2-layer Tread structure. We aimed to achieve both long life and WET performance, as well as grip performance that allows you to enjoy sports driving..
Hi SILICACompound is used in the Center section.
Silica and Carbon blended compound improves life performance..
[04]Profile
CamberTrustTuningTechnology.
Tuning the Front/Rear camber ThrustBalance to improve the turning force of the Front against the Rear.. Aiming for sporty handling characteristics, such as turning from the front.
ImpactParis - Technology.
Tuning the structure and profile to "for Sports", the lateral movement is suppressed while the longitudinal deflection is improved to achieve both absorption and rigidity at full bank.. Improved ground feel in sports driving while ensuring road-following performance..
[05]Jointless belt(JLB)
FrontAramidJLB. *Excluding some sizes
Succeeded in reducing weight by approximately 6% compared to Dunlop's conventional products. Sporty Handling and Comfortable Ride. Supports Rider's ability to maintain focus.
UFS JLB + Structural Optimization.
Achieved a weight reduction of approximately 12% compared to Dunlop's conventional product by reviewing the rigidity balance of the Tread and SIDE.. Improved ride comfort.

Comments from the Development Team
What is a true SportsTire?.
The sensation of turning in while slowing down and turning from the front of the car is uplifting..
Trace the targeted Line.. Passing through the clipping point, the vehicle body is raised and accelerated.. Engine RPMs going up.
Comfortable feeling of Rear gripping the ground..
Now the next Corner is coming up..
Grip performance sufficient for sports driving, nimble and stress-free handling to trace the target line.
Wet performance for more peace of mind in the event of sudden rain, life for long trips, and a comfortable ride..
SPORTMAX Q5A is a tire that can be used all-around while pursuing sports performance..
