Agreed. I have e-rated Wildpeak AT's on my Tundra, and every fall when I switch over to my Toyo winters in SL, I'm amazed at how much quieter, smoother and more comfortable they are by comparison.I had SL rate tires on my tacoma and just put them on my Land Cruiser. I did a number of light off-roading trips in my tacoma and never had a problem with SL rate tires. I went to Ouray for 5 days, windrock in TN for a weekend, Badlands in IN, and a few different trips to Northern Wisconsin without issue. The only time I would look at e-rated is if I was loading up really heavily with overloading stuff, hard rock crawling, or heavy towing. I really believe E-rated tires are overkill for most people. I had a friend who used e-rated KO2 and all he did was complain about the noise and rough ride.
