Dunlop Sport Maxx RT2

Strong spec profile
Estimated from manufacturer specs (UTQG, warranty, speed rating)
Scouter Analysis
The Dunlop Sport Maxx RT2 is a strong contender for drivers who demand top-tier dry and wet grip from their ultra-high performance summer tires. With perfect scores in dry grip and handling, it outperforms the category averages, making it a great choice for spirited driving. The wet grip rating of 9 further ensures confidence in rainy conditions, surpassing the typical segment expectations. The tire's 45,000-mile treadwear warranty is a standout feature, offering more longevity than the average in this category. However, while the comfort and noise scores are average for the segment, they may not satisfy drivers looking for a more refined and quieter ride. Competitors like the Michelin Pilot Sport 4S offer a more balanced comfort profile, while the Pirelli P Zero (PZ4) provides slightly better steering feedback. In summary, the Sport Maxx RT2 is best suited for performance enthusiasts who prioritize grip and handling. However, those who place a premium on comfort and noise levels might want to consider alternatives like the Michelin Pilot Sport 4S or the Pirelli P Zero for a more well-rounded driving experience.
