Important Note: It has been reported that some dealers have been advertising the Falken "RT-615K" but shipping the older "RT-615". There is only a subtle visual difference between the "RT-615K" and "RT-615". The performance difference however, is huge. The image below shows the "K" stamped on the side of the new "RT-615K". Rest assured when you purchase an "RT-615K" from Vulcan Tire Sales you will receive the new "K" version and all the performance enhancements that go with it. The Next generation Azenis RT-615 Tire. Street Legal Motorsports and DOT Approved Track Competition Tire (Meets SCCA street class requirements) New compound for ultimate street and track grip -Asymmetric Tread Design for improved dry lateral handling Lower outboard groove to-block ratio for maximized road contact during cornering 3 circumferential grooves for improved wet performance Solid center rib for great traction and lateral handling Chamfered center rib edge for minimizing distortion during cornering Larger inboard groove-to-block ratio for wet traction Ready for the track right out of the box! This tire's large tread blocks combined with a molded tread depth of 8/32 inch reduces "tread squirm" and the need for shaving. In addition, the RT-615K's tread compound is not susceptible to "chunking" eliminating the added expense of heat cycling that some track tires require.
