Our take

The Toyo Proxes ST III is a solid choice for drivers who prioritize treadlife in the ultra-high performance summer category, thanks to its high treadlife score and 40,000-mile warranty. While its dry grip and handling scores are competitive, they don't quite match the top performers in the segment, like the Michelin Pilot Sport 4S.

In terms of category priorities, dry grip and handling are crucial, and the Proxes ST III delivers adequately with scores of 8 in both. However, its wet grip rating of 7 is below the category average, which could be a concern for those frequently driving in wet conditions. The comfort and noise scores are average, making it a reasonable choice for daily driving without excessive road noise.

When compared to competitors like the Pirelli P Zero (PZ4) and Michelin Pilot Sport 4S, the Proxes ST III stands out more for its longevity than outright performance. The Michelin offers better grip and handling, while the Pirelli is known for its balanced performance across dry and wet conditions. If maximum grip is your priority, the Michelin might be worth the extra cost.

Drivers seeking a high-speed tire should look elsewhere due to the 'R' speed rating, which limits top-speed capability compared to the usual 'Y' or 'Z' ratings in this segment. Consider the Proxes ST III if you want a performance tire that lasts longer and don't mind compromising slightly on wet grip and top speed.

Pros

  • Treadlife score of 9 is notably high for an ultra-high performance summer tire, backed by a 40,000-mile warranty that exceeds the category average.
  • Dry grip rating of 8 offers solid performance, though it lags behind the category benchmark of 8.7.
  • Handling score of 8 aligns well with the dry grip, providing a balanced driving experience for spirited driving.

Cons

  • The lower wet grip score and 'R' speed rating may deter drivers looking for top-tier performance in all conditions.
  • Wet grip score of 7 falls short of the category average of 7.6, which may be a concern in rainy conditions.
  • Speed rating of 'R' is lower than typical for this segment, where 'Y' or 'Z' ratings are more common, potentially limiting top-speed performance.
  • The Michelin Pilot Sport 4S offers superior dry grip and wet performance, making it a stronger choice for those prioritizing maximum grip.
