“4 new Hankook Dynapro HT RH12 now installed in the CRV. Fresh production date (0618) and now made in the US. Thread looks slightly different than the replaced ones. They are quiet, track straight, no balancing issues and have a nice grip. Ride is a bit jumpy, not too much. $550 OTD with a $50 rebate. Son is happy.”

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.
