“I figure any tire review is good, even if late. I'm nearing the end of use for Cooper Discoverer AT3 XLT in LT275/70R18E 125S on OE 18x8" chrome clad wheels. They have been fantastic tires , great in the snow, quiet, never felt like they were giving up any traction except for the fourth (last) winter, but they never felt dangerous. They wore dead flat across the tread, kept the fronts at 65# and rears at 75#, rotated about every 5k miles, used Thuren alignment specs. They made 50k miles (the warranty in 2020) no problem. I have no problem getting them again or recommending them, but I like trying something different. If the different tires I chose this time don't work out (45 days), I'll just get these Coopers again.”

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.
