Although I realize I am not limited to just what is in stock at my nearest DiscTire, what they have now is interesting - not many in stock right now. They range from the $169 Trailfinder All Terrain, the $206.00 Cooper Discovers ATP II, the $209.00 Hankook Dynapro HT RH12, then a big jump up to the $277.00 Michelin Defender LTX M/S, and the YUGE $293.00 BFG A/T T/A KO2. I need a tire pretty much for road driving only. I do not often go out of town but for instance I've got a 9 hour trip later this month. It snows here in my area maybe..2 weeks / year, and nothing insane. So I don't really even need A/T tires in my opinion. The Hankook Dynapro seems to fit budget and looks like a good road tire. I can't tell which ones are Chinese but, sure, I'd love to avoid that too! Thanks for all the suggestions here.”

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.
