Falken Azenis RT615K+The Azenis RT615K+ is a further evolution of Falken Tire's championship-winning Extreme Performance Summer tire, the Azenis RT615K. Developed for drivers of muscle cars, sports cars, street rods and performance sedans who want ultimate grip in warm, dry and wet conditions, the Azenis RT615K+ is not intended to be serviced, stored nor driven in near- or below-freezing temperatures, through snow or on ice.

Utilizing the proven internal construction and motorsports-inspired asymmetric tread pattern as its predecessor, the Azenis RT615K+ features Falken's latest Extreme Summer Performance-targeted compound. The updated compound is designed to further satisfy the increased performance expectations of competitive drivers through additional dry grip. The Massive Sport Side Shoulder Blocks deliver extreme levels of lateral traction through turns, and the solid center rib effectively puts the power to the ground by providing constant contact with the road. Inboard circumferential grooves and notched tread blocks help evacuate water from the contact patch, improving wet traction and hydroplaning resistance.

Internal construction of the Azenis RT615K+ includes a high-tension casing to help increase handling response and high-speed stability. Twin, high-tensile steel belts are reinforced by a spirally-wrapped nylon Joint-less Cap Ply to promote even wear and durability.

Extreme Performance Summer tires exposed to temperatures of 20 degrees F (-7 degrees C) or lower must be permitted to gradually return to temperatures of at least 40 degrees F (5 degrees C) for at least 24 hours before they are flexed in any manner, such as by adjusting inflation pressures, mounting them on wheels, or using them to support, roll or drive a vehicle.

Note: Flexing of the specialized rubber compounds used in Extreme Performance Summer tires during cold-weather use can result in irreversible compound cracking. While compound cracking is not a warrantable condition because it occurs as the result of improper use or storage, tires exhibiting compound cracking must be replaced.

Continental ExtremeContact Force Reviews

Reviews highlight excellence in dry traction with strong grip and consistent lap times during track days, HPDE events, and canyon driving. Users praise predictable breakaway characteristics and heat tolerance across multiple sessions. Wet performance earns praise for damp-track confidence, though some note hydroplaning risks in heavy rain. Treadwear stands out as a strength, with many reporting 8-10 track days plus street miles remaining, though proper camber setup is critical to prevent shoulder wear. While not the fastest 200TW option for single-lap pace, drivers value the tire's endurance focus-maintaining performance through heat cycles without drastic drop-off. Ideal for those prioritizing longevity and session-to-session consistency over peak grip.

...I've done a handful of track days in the rain and they have been absolutely phenomenal. I know a lot of guys using them as a dedicated rain tire.

Awesome track tire that's consistent lap after lap and session after session. I can't compare it to any other 200tw tire as these are my first time using a 200tw. I've done a handful of track days in the rain and they have been absolutely phenomenal. I know a lot of guys using them as a dedicated rain tire.

...They offer great traction, very good steering response (they only come in relatively low profile anyway) and good predictability for hard cornering...

I use my Hyundai with these tires for track season, so mostly on good, warm, sunny days. They are great for aggressive driving in warm weather on the track or street, provided there are no potholes. They offer great traction, very good steering response (they only come in relatively low profile anyway) and good predictability for hard cornering. Not the best for cold or wet weather. I replaced Hankook RS4 tires with these and they are both very similar. Overall I'm very happy with them for track and good weather use, but pick some other Continentals for all weather daily driver.

...So far have lasted twice as long as my fast sticky tires of choice and still have life in them...

For driving my heavy car on track for HPDE/open lapping I have come to really appreciate these tires. Not the fastest tire out there in this segment, but fast enough and incredibly consistent. Holds up to temperature extremely well and doesn’t overheat prematurely. Very confidence inspiring and predictable. So far have lasted twice as long as my fast sticky tires of choice and still have life in them. These will be a go to option for me.

...I have put 3100 miles on my set and they show minimal / reasonable wear...

Very good high-performance tires for your weekend car. I have put 3100 miles on my set and they show minimal / reasonable wear. My car is 2500lbs, 600hp / 585tq - and these tires keep it glued to the road. In fact, unless it's wet, it is difficult to break these tires loose! Overall I would strongly recommend these tires.

Great track tires, tread wear is excellent, 10 track days so far and still have a lot of tread left. They get a little greasy in warm conditions, but stick really well in the first couple sessions or cool-warm days. Highly recommend

The category continues to expand, but it seems we have reached a performance plateau. To see if one of the two new Extreme Performance Summer tires can leapfrog the established leaders, we put them to the test.
