“I spoke too soon!! I have run cooper cobras in the past for years on my small pickups and they were fine. I just had a cooper cobra split on me on my '66. It's split right along the manufacturer's seam. ***UPDATE: I bought the tires from discounttiredirect. They contacted me and are shipping a brand new replacement tire out!”

How do we compare tires?
Every category score blends two independent signals. 60% comes from professional tire tests (braking distances, lap times, noise measurements), each result compared with every other tire in the same test and newer tests counting more. 40% comes from owner reviews found online, adjusted for how generously each site rates. Both use one scale: the average tested tire gets 70, the best 100. When a tire has only one of the two, the missing half is estimated from the other and the score stays closer to average; with no road test and fewer than five owner reviews it gets no score yet.
Handling is the exception: road tests measure it inside the dry and wet scores, so its own row comes from owner ratings only and starts as less important.
