The AZENIS RT**5K+ is derived from the original competition-winning RT**5K. The PLUS encompasses a digitally-engineered, nanotech-formulated compound enhancement for superior grip and excellent handling. On the track, the RT**5K+s confidence-inspiring straight line and cornering traits encourage drivers to push their vehicles to the limits in safe, closed-course environments. On the street, high-tension carcass construction provides added durability, ensuring this DOT-approved tire is capable of road-legal daily use.
