“I’ve run Hankook dynapro’s, BFG ko2, Nokian outpost nat, and fallen wild peaks. Currently running Cooper discoverer AT3 XLT - they are definitely the quietest all terrains I’ve had. I would recommend them if they are available in your size - many places like simpletire or priority tire carry them.”

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.
