Falken Azenis RT660 review

The Falken Azenis RT660 is widely regarded as a high-performance, cost-effective 200TW tire that excels in dry autocross and track-day environments. While it offers impressive grip, sharp steering response, and consistent performance once up to temperature, it is frequently criticized for its poor wet-weather capability, rapid wear, and reported manufacturing inconsistencies such as tread delamination.

The Falken Azenis RT660 is widely regarded as a high-performance, cost-effective 200TW tire that excels in dry autocross and track-day environments. While it offers impressive grip, sharp steering response, and consistent performance once up to temperature, it is frequently criticized for its poor wet-weather capability, rapid wear, and reported manufacturing inconsistencies such as tread delamination.

Pros

  • Excellent dry traction and cornering grip
  • Rapid warm-up time
  • High performance-to-cost ratio
  • Predictable and communicative handling at the limit
  • Consistent performance across multiple laps or runs

Cons

  • Poor performance and hydroplaning risk in wet conditions
  • Reports of tread delamination, chunking, or cracking
  • Rapid tread wear, especially under heavy track use
  • Lack of audible warning before reaching the limit of adhesion
  • Sensitive to heat soak on hot days or with heavy vehicles

Worth knowing

  • Heavier vehicles (e.g., Mustangs, Camaros) tend to heat-soak the tires faster, leading to a noticeable drop in grip during long sessions.
  • Users note that the tires run wider than standard sizing, which can lead to fitment issues or rubbing on vehicles with tight clearances.
  • Front-wheel drive, camber-limited cars may experience accelerated shoulder wear if not managed with proper alignment and tire pressure.

The Falken Azenis RT660 is praised heavily in the community for its exceptional dry grip, fast warm-up times, and competitiveness in autocross. However, users frequently note drawbacks such as potential delamination or heavy wear on aggressive track days, poor performance in heavy rain or standing water, and a tendency to heat cycle out before the tread is fully gone.
