The New RT-615K High Performance Tire From Falken
In the early 2000′s, Falken Tire came out with a budget, high performance tire that changed the auto crossing and road racing world – called the Azenis ST-215. Many local organizations contemplated banning the tire from STS and STX, street tire-based, classes because it performed so well. They were sticky from the start and maintained the 200 treadwear minimum needed to qualify for many street tire classes. They were cheap, with the popular tire size at the time being a 205/50/15 that came in at around $60 a tire. The sidewalls were ultra stiff and did not require a great deal of tire pressure to prevent roll over. The only downfall of the ST-215 is that it got over-heated after a short period of time and many racers brought bug sprayers filled with water to soak the tires between runs.
By the mid 2000′s Falken had replaced the RT-215 with the RT-615. Many were upset and wondered why Falken discontinued a tire design that was so popular. Fast forward to earlier this year and the RT-615 was reborn again, though this time with a K behind it. The RT-615K has been called the revolutionized RT-215, but even better. The tire technology behind the RT-615K makes the tire work like a 160-180 treadwear tire, with the 200 treadwear life. That means even better cornering and braking performance. Also with the new technology, Falken has figured out a way to keep the new K-series tires from getting slick when they are hot; now they heat up fast, and stay sticky. While the price of the new RT-615K has increased a bit, there is no doubt the performance is there to match.
