Every tire test we conduct represents but a single data point, and though we try to minimize variables in our comparison process, there will always be the chance that different results will be obtained with different weather, venue, driver, vehicle and setup. So what do we do? Test again. 

When we compared the current crop of R-comp tires a year ago–these …

Excellent article as always. As a numbers nerd I would love to see durometer testing before during and after as well as pyrometer results. Have a great track season.

Curious why you pay no attention to Hankook Z214.   I've used them for years.  Good tire with slightly less peak grip than R7, but flatter torque curve good for half a dozen more HC's.  Would love to see how you compare them to others in this test.

^ Agree with the performance assessment. I tried a set of Z214 in the medium compound, 205/50R15. However, at about 14 HC (20 minute sessions), one of them failed with an internal tread belt separation during a session. I exited early before anything catastrophic happened (it was hard to miss...), but that scared me off. I can understand defects and imperfections in something as highly consumable as a track tire, but that kind of failure is unacceptable as a safety hazard.

Performance-wise, they just aren't up there with the current crop.
