I was in the camp KO2 are super quiet, but that changes with mileage and sooner than I expected. At ~20k mark between 5 tires (I rotate in the spare) they become what I would describe loudish and sound almost as loud like my studded Nokians snows. Regularly rotated.
I don't have many miles on my Nitto RGs on my newer 200, but I am curious how they do over long run. They are louder out of the gate at lower speeds. New Nittos are much quieter at highways speeds than the KO2 with 20k miles on them.
I also run KO2s on my Tacoma. Only 11k miles but at ~4y mark they appear more slippery in wet than they used to - getting old/harder? Did not notice that on the 200 (yet?), but they are newer by a year. Need actually to check the date code to confirm.
Given the above and how PIA are KO2s to balance (road force a must), I don't think I will ever buy another set.

14 months and 20K+ miles on my current set of KO2's on the Cruiser rotating them every 5,000 miles and I've had zero issues with wear, balancing, noise, performance. They do tend to get louder at their half-life mark and beyond but we are talking 30,000+ miles on average. I have had a few sets of RG's as well and I found them louder when new and throughout their life, just like the KO2's, they too get louder with age and mileage. YMMV.

Not mine. 39k miles. Rotate every 5k. Mine is still quiet as before. The only thing that I have noticed is drop in fuel economy as KO2 ages.
What pressures are you guys running in the KO2's for your sound test?

46 psi which is what is recommended for my tire size.
Thanks. My truck came with highway tires and I've been trying to plan ahead. I've had a great experience with the KO2's on my 4runner, 90k on the first set, and about 20 on the second so far, but they are C rated running 44psi.
Trying to decide whether I want to go with them on the LC, looks like the choice is D or E and I have no experience with anything other than C.
38-40 psi, 275/70/18's.

I am running stock sized KO2 load range D. 46 psi.
Finally remembered.
Angle was very hard with the S4 as the screen isnt always on. Tried to get the gauges too. Bounced between that and 65 at peak. Settled around 63-64 though. It quickly shoots up after that.
285/70r17 Toyo A/T3 C 35-36 PSI
65 MPH cruise

If possible go 80-82 mph and see…because then we can compare apples to apples.
Yeah i will next time i am actually going somewhere more than one exit!
Ok, i ended up just shooting a video, here is the best frame that shows the proof!
Pretty damn quiet! Not too bad Toyo…
Also, I have some wind leak issue ive been chasing that i need to fix so i believe i can get it even lower. I think the tint is cut too low on the window and the seam is sitting right at the point it is supposed to seal with the rubber trim. Thats my latest theory anyway.

Update. 40,075 miles. Same Apple Watch series 4. Same tires (Stock sized KO2). 82 mph on highway this morning. Pretty much same noise level as before.
I am pretty impress with KO2 quietness on highway so far, even this late in life.
