Bridgestone Potenza RE-71RZ vs Falken Azenis RT-615K+ tires on handling

Let us now find out which of the two UHP summer tires offers better handling performance so that you get confident stability, ride control, in-time steering response, strong braking performance, and seamless cornering on tracks and streets in warmer weather conditions.

The highly capable Potenza RE-71RZ showcases world-class handling with an outstanding 9.1 SimpleScore. Its reinforced internal carcass and stiffer sidewalls combat lateral stress, while the solid center ribs ensure seamless steering and lane changes. This tire also features massive slick outer shoulder blocks that expand the footprint for confident heavy cornering during high-speed driving.

In contrast, the Azenis RT-615K+ achieves a great 8.3 SimpleScore in the handling area. The solid center rib and robust sidewalls enhance steering response, while the optimized footprint with sturdy blocks provides the much-needed cornering stability. Overall, the footprint is tuned to provide in-time braking in dry and wet conditions for a confident driving experience on tracks and streets.

In handling, it is again the Bridgestone tire that wins by a big margin, securing a 2-0 lead against the Azenis RT-615K+.

Bridgestone Potenza RE-71RZ vs Falken Azenis RT-615K+ tires on longevity

Let’s now find out which of the two performance tires offers higher value on purchase by lasting longer under high-speed driving pressures and covering more miles.

Starting with the Potenza RE-71RZ, the tire earns an 8.0 SimpleScore in longevity. The tire is track-focused and hence utilizes a soft racing polymer compound, which doesn’t let it last as long as the standard all-season tires or UHP all-season tires. However, the use of proprietary ENLITEN technology contributes to extended service during extreme performance.

On the other hand, the Azenis RT-615K+ scores an equal 8.0 SimpleScore in longevity, offering reliable service life. As a 200 UTQG competition-oriented DOT summer tire, this rating is good enough to ensure the tire can resist wear very well under driving pressures. Like its peer, you won’t get a tread life warranty, but its heat-resistant nanospec compound can resist tread chunking well during hot track sessions to provide a similar service life to the Falken tire.

The identical 8.0 longevity scores of both track-focused summer tires conclude this section with a perfect tie!

ADVANTAGE: Tie

When to use each

The Potenza RE-71RZ and the Azenis RT-615K+ are both UHP summer tires, and these extreme-performance summer tires should be used in temperatures above 45 degrees Fahrenheit.
