    I have been driving an average of 60,000 a year for several years, regardless of the road conditions, which is why I put good tyres on. Until now, I have mainly used high-end brands and model brands: mainly Michelin, I also had Pirelli twice and Good Year. Due to the car's power and aggressive driving style, the tyres did not last long. In the case of Dunlop I decided to do a small experiment because the tyres had very good reviews and the price was tempting compared to the above-mentioned brands (the difference on only one tyre reached about 30 GBP). I was not disappointed, and even I am very happy with the choice. I will purchase Dunlop for winter as well. The tyres are really very quiet, they keep well in sharper corners and on a wet road they are draining water well. An important element for me is also the tyre durability, so far after 15k you cannot see any special wear - I think they should last for 60-70k. Visually, they also look great, I think the tread pattern fits both sports cars and limousines. I would recommend - a great compromise between quality and price.

    I've traveled about 13kkm on tires. My driving style is very diverse, from calm to very dynamic (not to be confused with aggressive). At the moment, I haven't noticed the major drawbacks of this tyre. As for the noise it is not too high and actually with the diesel engine barely audible. Behavior on dry surfaces: the tyres perform very well, I did not see any slippage when cornering at a reasonable speed, and the car is quite difficult to unbalance. However, wet is a bit worse. With dynamic starting, it happens to lose traction, but when driving at a constant speed, even on the highway, the water is drained very well from under the wheels. When sudden braking on dry car does not lose grip, unless there is some sand, in the wet it is way easier. Suppressing unevenness is not the best, but for a fairly low profile it is good. As for tire wear, it is hard for me to say something more, I have traveled only 13kkm on them. I also did not notice that the tyres behave somehow unnaturally. Failure rate: none. In short, I highly recommend.

    Generally a tiye worth recommending, I know what I’m taking, but there are a few comments. First of all, what hurts the most - I got tyres with three production dates (2x1114; 0814; 2014). 1x1114 and 1x0814 landed (unfortunately) on the front axle. Effect? Above 120km / h, pull to one side (without beating; without any vibrations; after accurate balancing). After changing wheels L <> P pull to the other side. Evident greater rolling resistance in one of the wheels. After mounting on the front 2x1114 the problem disappeared. Solution? Order tyres only with the same production date. The second thing is volume. I knew it would be louder but not so;) But ... generally a tyre worth recommending. Grip great. With dynamic turning the steering wheel floats a little (pressure 2.6), but let's say that fresh rubber with a high tread and a soft compound. The grades I've posted relate to the set that I received in one delivery. Poor "behavior on the road". I suspect that if I got tyres from the same date, the ratings would be maximum.

    SP SportMaxx RT are supporting car on mountain roads very good. On highway SP SportMaxx RT are doing very good, other words: a very good tyre! However, only on Highway. I was riding Conti Sport 3 earlier and they were awesome on both asphalt and country roads. SP SportMaxx RT are not doing well on country roads. SP SportMaxx RT are made from soft compound which makes them wear significantly faster, but are great on asphalt. I will look for forest efficient tyres or country roads great both on asphalt and country roads. Continentals were just like that...

    Tyres offering good grip in turns, dry and wet surfaces, short braking distances BUT... after 6 months and about 7000 miles of regular driving an average car, these tyres are nearly gone!! Tracking done with tyre fitment. No matter how good the tyres are, but if they only last for less than one year...? Both front and rear! Absurd!

Product description

Dunlop SP SportMaxx RT MFS 225/45 R17 94 W XL, MFS

Technical description: The Dunlop SP SportMaxx RT is the successor to the Sport Maxx TT model. It is noted for its improved braking and going round corners and, thanks to the use of an innovative compound, the car reacts faster to steering movements. The tyre's excellent stability when negotiating corners and moving at high speed is down to its massive side wall. The system of tread grooves effectively disperses water and protects against the risk of aquaplaning.

The model is made using a special sporty compound, which helps the tyre adapt to different types of surface. The even distribution of material and the aerodynamic side of the tyre reduce rolling resistance, resulting in lower fuel consumption and a reduction in CO2 emissions.

The designers have also managed to ensure optimal performance from the tyre thanks to its construction using Racing technology, which increases driving comfort and ensures a greater level of safety and better driving precision compared with other tyres of the same class. The car also reacts extremely well to even the most minor steering corrections, thus improving driving stability and making the driving experience genuinely enjoyable.

The Dunlop SP SportMaxx RT is installed as an original part in the Mercedes C63 AMG and C63 T.

Information about the manufacturer: Dunlop is one of the best known tyre producers in the world. The brand currently belongs to the Goodyear group. Dunlop tyres were used to break the first speed records before the Second World War. Dunlop tyres are renowned for their innovative solutions and fare well in prestigious tests carried out by specialist organisations and renowned motoring magazines. Right from the start, the brand has been associated with motor sports and has achieved great success in this field. The company specialises in the production of HP and UHP tyres, noted for their excellent quality and optimal performance in any conditions.


The Dunlop SP SportMaxx RT MFS tyre in size 225/45 R17 94 W, according to the manufacturer's information, has the following drivability qualities:

  • C
  • B
  • 67 dB
C B 67 dB

Fuel efficiency (rolling distance)

Fuel efficiency is rated from A to G on a colour-coded scale. The highest fuel efficiency rating is A (green; the lowest rolling resistance), while the lowest fuel efficiency rating is G (red; the highest rolling resistance). Rolling resistance influences fuel consumption and vehicle emissions; the lower the resistance, the lower the fuel consumption and exhaust fume emissions.

Wet grip

Wet grip is the tyre's ability to adhere to the road surface in wet conditions. The EU rating focuses only on the wet braking performance of the tyre. Wet grip is rated from A to G, where A represents the best braking performance and G represents the worst. It is one of the most crucial safety parameters.


Tyres contribute to the amount of noise a vehicle generates. Choosing a tyre with a good noise rating will lower the impact of your driving on the surrounding environment.
