“Tire Recs for F150 - mostly highway and some muddy field edges - Cooper or Falken? I mostly put highway miles on my 2011 F150 but Im a bow hunter so October and November I spend a decent amount of time driving on field edges to get to hinting spots. When its wet, these field edges get pretty sloppy. I have Cooper Discoverer AT3 4S currently. While Ive never gotten stuck, there's been a few sweaty moments where it felt close. These have been great on road tires with low road noise, great fuel efficiency, and impressive handling in wet, dry, and snow. I want to maintain on road performance as thats 90% of my use, but curious if there are any thoughts on the new Cooper Discoverer Road + Trail AT, vs Falken Rubitrek, or Falken Wildpeak AT3 or AT4. Im leaning going Coopers again and hoping for the best on those occasional muddy mornings. Let me know thoughts and experiences. Read more”

“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?”

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.
Community buzz from Reddit and forums is shown for context only — it never changes the score.
