Dunlop Sport Maxx RT2, tested by rezulteo

New tyres Published the 24/05/2016 by Julien Taillandier

The Dunlop Sport Maxx RT is considered to be a benchmark in the sports tyre domain. After 4 years of loyal service, it is replaced by the RT2 which builds on its predecessor’s values.

The difference in positioning between the Goodyear and Dunlop brands has never been as clear-cut as at the launch of their two new UHP (Ultra High Performance) tyres, respectively: Dunlop Sport Maxx RT2 and Goodyear Eagle F1 Asymmetric 3.

Indeed, these two tyres which are in direct competition claim to address different targets despite a common market segment. While the Goodyear is aimed at high performance and safety, the Dunlop is clearly designed for driving pleasure.

Road tyre or semi-slick tyre?

Let there be no mistake, the Sport Maxx RT2 is a standard road tyre with all the resulting versatility, but like a Michelin Pilot Supersport or a Continental SportContact 6 its sportiness inspires more confidence than a standard high performance tyre.

Although this tyre is clearly designed for sporty road use and occasional track use, it in no way sacrifices essential features such as longevity (35 %  more miles than the RT) and safety, particularly in terms of wet grip. A test conducted by the TüV SUD test organisation has highlighted its expertise in the domain.

Test on the Mireval track

The RT2 is the technological showcase for Dunlop’s extensive racing experience. It aims to be a tyre with character, and takes the necessary steps to achieve its objectives, the first of which is to bring pleasure.

According to Dunlop, whether it be its casing (ultra resistant), its tread design (with reinforced shoulders), or the latest generation tread compound, all aspects of this new tyre have been developed with these requirements in mind.

To check this out, Dunlop gave us access to their test centre’s speed track. Characterised by its very technical layout, this track comprises slow sections, blind corners and significant variations in altitude. For the test, we had a 381 hp Mercedes Cla 45 AMG Shooting Break, a powerful, but relatively heavy car (more than 1600 kg) for our track test. During this test drive, our analysis focused on aspects relating to this type of use such as steering precision, durability or feeling.

From the very first laps, the RT2 took us by surprise with its responsiveness. Without being as lively as a semi-slick tyre, its steering response was immediate, with no lag.

The steering angles required to position the car when entering corners were moderate, leaving no room for a floating feeling. When the tyre was pushed to its limits, there seemed to be no conflict with electronic devices and good use was made of the power. Driving pleasure was undeniable, allowing good lap times to be set without the tyre falling into an under- or over- steering phenomena over the laps.

However, the tyre seemed to be noisier than the average tyre when pushed hard.

Note that for exclusive track use, it is better to change to a more extreme product such as the Dunlop Sport Maxx Race.

In which sizes?

The Michelin Sport Maxx RT2 is now available in 48 different sizes for 17 and 21-inch rims.
