DUNLOP EXPLANDS SPORTMAX LINE WITH THE ADDITION OF THE TRACK DAY HIGH PERFORMANCE Q4
Here’s the first think you need to know about Dunlop’s all new Sportmax Q4: This purpose built track day tyre achieves lean angles up to 62 degrees, more than any other street legal tyre Dunlop has ever made.
Utilizing technology shard by Dunlop’s cutting edge Moto American road race tyres, the Q4 is made in Dunlop’s Buffalo, New York plant on the same proprietary equipment as the racing products – Only Dunlop makes sport tyres in America.
Over the years, Dunlop has developed many class leading sport tyres as well as racing tyres for professional and amateur road racers. The hypersport Sportmax Q3+ combines both, with one foot on the street and the other on the track, performing amazingly well on track days considering it’s built primarily for aggressive street riding.
Now the Q4 takes that performance to a whole new level. The Q4 is not a Q3+ replacement but is instead designed to add depth to the Sportmax family line up to accommodate track day level riding like no other Dunlop DOT street tyre has before, with even greater overall performance and grip than the Q3+.
STREET FRIENDLY, TRACK READY
Visually, the first thing you notice about the Q4 is bold look. Utilizing special moulds, Dunlop was able to create bold on-tread branding for the Q4 that’s remarkably detailed, and the sharply defined new tread pattern with low grove density puts more rubber on the ground at all lean angles.
With far more land area and fewer tread groves than the Q3+, the Q4 puts down a massive footprint, especially during maximum lean angles. Despite this significant performance, the Q4 is also as user friendly as a street tyre – it performs well in the wet, warms quickly, does not require tyre warmers, and is engineered to run on the track at close to street pressures, minimizing the need for chassis adjustments.
The Q4 was also designed in new sizes of 180/60ZR17 and 200/55ZR17 to work on sport bikes with sophisticated electronics packages. Those new sizes also offer a more aggressive profile option for track use for many sports bikes. (180/60ZR17 not currently available in Australia)
TECHNOLOGY FROM THE TRACK
Racing technology drove the Q4 design. The rear tyre compound itself has no silica – it’s all carbon black like Dunlop’s racing slicks for maximum grip. Construction also follows Dunlop’s race tyre protocol: The rear tyre features Dunlop’s Jointless Tread (JLT) technology. Using the same process as Dunlop’s racing slicks, sophisticated product machinery in the Buffalo plant winds the tyre tread compound over the carcass in a narrow, continuous stip. This continuously wound strip allows Dunlop to achieve the ideal stability, flex and grip where it’s needed most across the tyre’s tread profile.
JLT helps increase tyre stability and reduce flex and helps create a larger more consistent footprint during braking, cornering and acceleration. Another benefit of JLT construction: The rear tyre is up to one pound lighter than the same size Q3+, so there’s less mass for increased acceleration.
Both front and rear tyres also utilize Dunlop’s proprietary Carbon Fibre Technology (CFT) in the sidewalls for even greater stability. CFT places a carbon fibre reinforcement element in the tyre sidewalls. This innovation delivers exceptional cornering stability especially at high lean angles, responsive and precise steering characteristics and predictable and smooth transitional steering performance for more confidence inspiring handling. Carbon fibre’s high stiffness, high tensile strength, low weight, high chemical resistance, high temperature tolerance and low thermal expansion make it a great match for application in the Q4.
The Q4 also features Dunlop’s proprietary Intuitive Response Profile (IRP) for ultra-linear and responsive steering. This innovative profile design allows for a taller tyre profile along with sizes that taper in more aggressively for remarkable turn in response and feel. Cross sectional analysis demonstrates this design creates a larger contact patch when cornering.
The user-friendly Q4 does not require tyre warmers, and runs at street pressures, eliminating the need for chassis or electronic adjustments

Q4 development took place over a year and testing was done at Dunlop’s Huntsville Proving Grounds (HPG), Virginia International Raceway, Chuckwalla Valley Raceway and Roebling Road Raceway, by Dunlop staff as well as professional racers. Several new compounds were developed and tried, with the final mix contributing to lap times that were more than a second quicker than the Q3+.
According to the newest HPG test rider, Taylor Knapp, the most apparent advantage of the new Q4 on the race track is grip and predictability.
“It’s like a slick”, said Knapp. “Handling is really predictable, you can brake later and get on the gas harder and earlier, and that chips away at the lap times and all the way around the track.”
