Our take

The Dunlop Sport Maxx RT is tailored for drivers who put a premium on dry and wet grip. With a perfect dry grip score of 10 and a wet grip score of 9, it surpasses the category averages, making it a compelling option for those who enjoy pushing their vehicle to the limits in both dry and rainy conditions.

In the ultra-high-performance summer category, dry grip and handling are paramount, and this tire excels with top scores in both. However, the tradeoff comes in the form of treadlife. The UTQG treadwear rating of 240 is significantly below the category average of 935, suggesting a shorter lifespan. Additionally, the lack of a treadwear warranty means you'll need to monitor tread depth closely and budget for more frequent replacements.

When compared to competitors like the Michelin Pilot Sport 4S, which offers a 30k-mile warranty, the Sport Maxx RT's cost of ownership may be higher over time. Comfort and noise are average, which might not satisfy those looking for a quieter, more comfortable ride. If longevity and a quieter ride are priorities, consider the Michelin Pilot Sport 4S or Pirelli P Zero (PZ4) instead.

Pros

  • Perfect dry grip score of 10, significantly above the category average of 8.7, making it a strong choice for spirited driving.
  • Wet grip score of 9 outperforms the category average of 7.6, providing confidence in rainy conditions.
  • Handling score of 10 ensures precise steering response, ideal for performance enthusiasts.

Cons

  • Lack of a treadwear warranty and lower treadwear rating mean higher replacement frequency and cost over time.
  • No treadwear warranty, unlike the Michelin Pilot Sport 4S, which offers a 30k-mile warranty.
  • Treadwear rating of 240 is lower than the category average UTQG of 935, indicating a shorter lifespan.
  • Comfort and noise levels are average, scoring 6 and 6.5 respectively, which may not satisfy those seeking a quieter ride.
