Our take

The Dunlop SP Sport Maxx GT is a compelling choice for performance enthusiasts who value top-notch dry grip and handling. With perfect scores of 10 in both dry grip and handling, this tire is designed for those who want to push their vehicle to its limits on dry pavement. The wet grip rating of 9 also ensures that it handles rainy conditions better than many in its class.

The tire's 50,000-mile treadwear warranty is a standout feature, significantly exceeding the category average and suggesting a longer lifespan than typical ultra-high-performance summer tires. However, the tradeoff comes in the form of comfort and noise, both of which are rated at 6 and 6.5, respectively, aligning with the segment's average but falling short of more refined competitors like the Michelin Pilot Sport 4S.

Compared to its competitors, the SP Sport Maxx GT offers a longer treadwear warranty but lacks the comfort and noise refinement found in the Michelin Pilot Sport 4S. The Pirelli P Zero (PZ4) may offer a more balanced performance for those who seek both handling and comfort. Ultimately, this tire is best suited for drivers who prioritize performance over comfort and are willing to accept some road noise as a tradeoff.

If you're looking for a quieter, more comfortable ride, consider the Michelin Pilot Sport 4S or Pirelli P Zero (PZ4) instead, which offer a more balanced approach to performance and comfort.

Pros

  • Dry grip score of 10 and handling score of 10 — both are at the top of the ultra-high-performance summer category.
  • Wet grip rating of 9 surpasses the category average of 7.6, making it a strong performer in rainy conditions.
  • 50,000-mile treadwear warranty is significantly above the category average of 37,754 miles, offering better longevity than many competitors.

Cons

  • Average comfort and noise levels may deter those who prioritize a quieter and smoother ride for daily use.
  • Comfort and noise scores are average at 6 and 6.5, respectively, which may not appeal to those seeking a quieter ride.
  • The Michelin Pilot Sport 4S offers a more refined balance of comfort and noise, appealing to those who prioritize a smoother drive.
  • Despite the high performance, the UTQG treadwear rating of 240 suggests a softer compound that may wear faster under aggressive driving.
