“New shoes on my ‘23 XSE Wanted to stick with black rims but saw these on an older gen and loved the look. Wrapped in 245/65R17 Hankook Dynapro AT2 Xtreme‘s. Also replaced the OEM springs with Eibach lift springs for a bit more ride height.”

“Tire Question: Michelin Defenders or Cooper Discoverer AT3 4S I have a TRD ORP and want to replace the crappy stock Dunlops. Almost all my driving is on road so looking at the Michelin Defenders or the Cooper AT3 4S in the stock size. I prefer the looks of the coopers but am I going to notice any decrease in wet performance, road noise or mpg compared to the Michelins?”

Positive
Hankook Dynapro AT2 Xtreme
Community sentiment toward the Hankook Dynapro AT2 Xtreme is largely positive, with owners frequently praising its aggressive appearance and confident performance in snow and wet conditions. Drivers also appreciate its comfortable ride quality compared to competing all-terrain tires and its strong 70,000-mile warranty. While noted as being slightly pricey and showing minor trade-offs in dry handling due to aggressive lugs, it is widely favored as an upgrade over older all-terrain models.

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.
