Hello. I saw your post whilst roaming the forum and thought I can give my opinion. I have a 2016 Trail Premium and am running BF Goodrich T/A KO2 tires 285/70 R17. I bought them immediately along with Pro Comp rims after purchasing my 4Runner 3 years ago. So far I have taken them in mud, snow, and sand and have yet had an issue. I have 65k mikes on them and dealer told me last week during my oil change I still have 40% tread left. I have driven from California to Florida twice, just to give you an idea of the road conditions these tires have been through. When I lived in CA and had quads I would pull them on the 2500lb uhaul trailer and would take them to sand dunes like Sandy Hallow in Utah or Superstition and Glamis in California. Not once did I get stuck. The tread on these tires make it for a quiet ride and have overall great offroad capability. This new version of the tires that came out a few years ago added a thicker portion where the tread meets the sidewall and it helps with traction should you decide to rock crawl or something like that.
Thanks for the write up! The BF T/A KO2's are giving you very impressive mileage longevity for such an aggressive off road tire . They certainly look good for a vehicle like the 4Runner. The vast majority of my driving is in the city and on the hightway. So, smooth riding, excellent rain performance and low rolling resistance for the MPG would be considerations.
The OEM tires on my 2015 TRD are the Nitto Terra Grapplers (265/70-17). They are a bit noisy on the highway. I wonder how the K02's might compare to the Nittos in terms of highway noise, wet conditions, and longevity ? I don't think the Nitto's great in the rain on highways, I'd rate the tire maybe a C plus overall.
