Dunlop Sport Maxx RT 255/30 ZR21 (93Y) XL, with rim protection (MFS)

Motorsports grip and braking for a dynamic driving experience

The Dunlop Sport Maxx RT delivers motorsports grip and braking performance for a dynamic driving experience.

Exceptional grip on wet and dry
Enhanced cornering control
Shorter braking at motorway speeds
Fuel efficient design

Advantages:

Excellent wet grip
Shorter braking distances
Ideal for sporty driving

Shorter braking distances. Dunlop’s innovative Short Braking blocks help to ensure shorter braking distances when travelling at speed. Designed for high performance driving, these extra stiff blocks increase road contact under braking force.

Exceptional grip. The SportMaxx RT delivers superb wet and dry grip thanks to adaptive compound technology. Motorsports derived polymers adapt to the textures of the road surface, maximising road contact and increasing grip.

Enhanced cornering control. Enjoy stable high speed handling with smooth transitions from straight to curve. Massive outer shoulder blocks help to enhance stability and handling when cornering.

Fuel efficient design. The SportMaxx RT employs a lightweight construction to reduce rolling resistance - lowering fuel consumption and CO2 emissions.

Tyre description:

Motorsports grip and braking for a dynamic driving experience: Exceptional grip on wet and dry, enhanced cornering control, shorter braking at motorway speeds and fuel-efficient design. The SportMaxx RT introduces new technologies derived from motorsport like the adaptive compound to provide a tyre that is a champion in grip and braking. Its grip on dry roads will outclass any rival.

Technology (Features):

Adaptive compound for a ‘racing’ grip and improved braking performances
Massive outer shoulder block for increased stability and better handling when cornering
New ‘power braking’ blocks for a shorter braking distance especially at high speed
Low Weight Construction, for improved Rolling Resistance performances

Consumer benefits:

Great steering response at high speeds
Ultimate grip in wet conditions
Excellent acceleration and braking performance
Very good control on dry and wet surfaces

Specific bead seat system. Strengthens the link between tyre and rim for a more precise driving experience. Like the grip between your hand and the steering wheel, the Specific Bead Seat System enhances control and conveys outstanding road feedback. Benefits Enhanced road feedback; greater stability and precision.

Adaptive Compound. A compound technology that uses motorsports derived polymers to adapt to the texture of the road surface. With enhanced contact at the micro level, overall tyre to road contact is increased.Benefits Superior grip and braking performance.

Power Braking Blocks. High stiffness blocks that maintain rigidity when braking force is applied. The increased stiffness helps to ensure optimal road contact when braking at high speeds.Benefits Shorter braking distances, especially at high speeds.

Silica-Plus Compound. A motorsport derived tread compound that delivers high levels of grip, particularly on wet roads and in low temperatures.Benefits Superb braking and acceleration performance; high grip in wet and cold-weather conditions; low wear and tear.

Jointless Belt (JLB). A Hybrid Overlay Technology that reduces circumferential deformations at high speeds.Benefits Superior high speed stability Maximum Flange Shield (MFS). A rim flange protection system. MFS employs a profile of rubber that runs around the circumference of the tyre above the wheel flange. This creates a protective buffer zone.* Benefits Protects expensive alloy wheels from kerbing.* Only available in select sizes.

Asymmetric Tread Design. Asymmetric tread design provides improved handling and aquaplaning resistance. The continuous center rib increases stability and precision. The asymmetric groove arrangement enhances grip on wet and dry surfaces.Benefits Improved performance on straight lines and around corners.

Flatter tread profile. The new generation of Dunlop tyres features a flatter tread profile with a 4-8% bigger contact patch, depending on size and type of tyre. A bigger contact patch delivers more stability and enhanced road feedback, allowing tires to respond quickly and precisely.Benefits Increased stability and steering precision; reduced heel and toe wear; excellent cornering stability and precision; superior dry grip.

Multi Radius Tread (MRT). MRT designs employ ten different radii and are therefore more precise. This results in highly effective pressure deployment on the road contact patch. The effect is smoother transitions from straight to corner, leading to more precise and progressive reactions.Benefits Significantly better control over the evolution of the footprint in all driving conditions; responsive wet and dry handling; increased cornering control.

Dual Silica Compound. This compound improves acceleration performance and promotes low wear and tear.Benefits Superb braking and acceleration performance.

EU Tyre Label and Efficiency Classes

The European Union has introduced the EU Tyre Label by Regulation (No. 1222/2009) identically and bindingly for all EU member states. It applies to passenger car tyres, light commercial vehicle tyres and heavy commercial vehicle tyres produced after 01.07.2012.

Three different areas are tested: rolling resistance, wet grip and the rolling noise the tyre makes on the road.

The following are not affected by the EU Tyre Label: retreaded tyres, professional off-road tyres, racing tyres, tyres with additional devices to improve traction such as spiked tyres, T-type emergency tyres, special tyres for fitting to vehicles first registered before 1 October 1990, tyres with a maximum authorised speed of 80 km/h, tyres for rims with a nominal diameter of 254 mm or less or 635 mm or more.

With this regulation, the European Union is pursuing the goal of promoting economic and ecological efficiency in road traffic as well as increasing road safety on the one hand, and on the other hand, granting consumers more product transparency and at the same time serving as an active decision-making aid.

Already during the incorporation, experts criticise the fact that the EU Tyre Label unfortunately only shows a few product characteristics. Apart from rolling resistance, wet grip and rolling noise, which are the main focus of EU tyre labelling, tyres have much more important and safety-relevant product characteristics, such as aquaplaning properties, driving stability, service life, braking properties on dry and wet roads, behaviour in wintry conditions, etc.

Tyre manufacturers point out that test results from various institutions and journals remain an important information medium for the end consumer. These tests usually focus on further safety-relevant product characteristics besides the EU standard qualifications for tyre labelling, which are always important for the final customer.

03/2014	GUTE FAHRT		Highly recommended Auch der Dunlop hat eine Werksfreigabe - die von Audi für den Q3. Was sich in harmonischen, präzisen Handlingeigenschaften mit sehr gutem Haftungsniveau zeigt. Gut ist der Komfortable Sport Maxx RT dazu beim Nassbremsen und in Sachen Rollwiderstand. Top ist aber auch die Aquaplaningvorsorge und das Bremsen auf trockenem Asphalt, Lastwechselreaktionen sind Ihm fremd. Dafür gibt es die GF-Empfehlung.

excellent tyres for very reasonable price. definitely would buy them again

10.09.2015 from GES
Supposed to give excellent fuel efficiency. Getting poorer MPG that I did from my Continental Sports! Difficult to say but wear does not look too good on front, doubt I'll get another 12k out of them!

09.09.2015 from Joseph Kinney
Starting to lose some of that high end grip when pushing hard but a very good tyre, great performance and very predictable.

02.07.2015 from Saulius
Very good tyre, but wears very quickly. But again, if you want solid grip in wet, the compound has to be soft and it means it will wear quicker than others. Had p-zero previously, was a bit noisy, dunlop makes much less noise.
