Tyre Tech Talk – July 2020 Dirt and Trail Magazine
by Bruce de Kock, Owner of Bike Tyre Warehouse
Original article published by Dirt and Trail Magazine, July 2020 Issue
I wrote a couple of months back about the new Dunlop Trail Max Mission 50/50 adventure tyres and while busy I made a mental note to do a scribble on their road range as there has not been much written on their road range, which is not small by any means. We are just restricted to what the distributor brings into SA from the full range of offerings.
Again, I have not personally ridden or tested any of the four that I am going to include in the spread I have chosen to kick off with their basic road product: the Sportmax GPR300 to the high end Q4 hyper sport tyre.



Dunlop GPR300 SportMax
The GPR300 is described as a radial tyre that offers well balanced sport performance for a variety of sport bikes featuring an optimized construction to enhance handling and responsiveness for street going sport commuter riding.
The advanced belt design and (JLB) jointless band construction utilizes a continuously would belt for smooth performance and a consistent tyre contact patch, the aggressive sport derived tread pattern for enhanced on-bike appearance. A product ideal for your everyday commute.
Dunlop RoadSmart III

Moving onto their Sport Touring Sportmax Roadsmart III– an offering Dunlop says offers sport touring riders ultra-high mileage with sport bike level grip.
Outstanding wet weather performance and great overall handling add to this tyre’s versatility. Dunlop’s exclusive MT (Multi Tread) design binds a high – mileage compound to the centre and high-adhesion compound to the lateral flanks for cornering grip.
The new sidewall construction helps provide superior shock absorption and precise handling, the new compounds include an innovative resin that increases wet weather grip, so maybe a tyre to look at when you are next fitting rubber to your sport tourer.

Dunlop SportMax Q3+
Now on to the high-speed, knee down rubber that starts to get me excited namely the Sportmax Q3+, a tyre Dunlop reckons is the ultimate in hyper sport tyre performance for serious sport and track day riders. Obviously written before the launch of the Q4 but we will get into that tyre just now.
Dunlop really pushes the tyre life point on this tyre as with all hyper sport tyres mileage is not one of the attributes for obvious reasons. The Q3+ was designed and is produced in the Buffalo plant in the USA, using the same high-tech production equipment as Dunlop’s racing tyres. The Carbon fibre technology (CFT) employed in the Q3+ uses carbon fibre reinforcement in the tyre side walls for exceptional cornering performance and feel.


The Q3+ rear tyre uses a silica-infused, long wearing compound in the centre of the tread for longer tread life, and special lateral grip compound on the left and right shoulders for outstanding grip.

Dunlop SportMax Q4

The Sportmax Q4 a bold look, bold performance for riders with balls, this is a proven purpose-built track day tyre that achieves lean angles up to 62 degrees.
A Big Win it is DOT approved for street legal uses or for the road racing boys. A logical choice. Why? Because you don’t require tyre warmers, you run the mat street inflation pressures which eliminates the need for electronic or chassis adjustments.
The carbon fibre reinforcement in the sidewalls creates exceptional cornering performance and feel. The rears contain carbon black like Dunlop’s race slicks for maximum grip at full lean angle and with Dunlop’s claimed IRP i.e. Intuitive Response Profile which is like the tyre knowing what you are thinking.
Anyway four Dunlop tyre options available whether you are a sport commuter, sport tourer, sport rider or a fast gun track / road racer there is a tyre in this article for you and with Bike Tyre Warehouses Dunlop Campaign kicking off on the 1st August you are guaranteed to get any of these tyre set ups for a great price as well as standing in line to WIN one of four lids just by buying a set during August or September so get down to Bike Tyre Warehouse and stake your claim on some Dunlop rubber.
Its getting warmer and more bikes are getting back out onto the roads around the country, so if your bike has been standing in the garage for a few months make sure you give it a full inspection as well as checking the condition of your tyres and tyre pressures before you ride out and open up the throttle.
Take care
