I run the BFG K02 285/65R/18 E rated at 40 psi on the 2016 LC200 with BP51 suspension with 2.5 inch lift. stock wheels/rims. I love the ride with this set up. My 2014 4runner with 182k miles on it , i am the original owner on it's 2nd set of BFG K02 275/70R/17 E rated also at 40 psi. they felt a little hard initially on stock suspension, but when i changed to Bilstein heavier duty suspension. they are awesome. Couple friends who drive a Tacoma and a Chevy when they ride with me in LC200 say how smooth and comfortable the ride is. Sorry you are having a bad experience with your K02s.
