I owned two sets of the BFG KO on my now sold 2003 F-250. They were great tires. Close to 50K on each set. Just before I sold my '03, I installed Toyo Open Country A/T IIs. What a difference in all aspects of driving, both highway and gravel roads. The Toyo Open Country were even better than the KOs to my surprise.
So when it came time to consider new, larger tires and smaller diameter wheels for my 2016 F-350, I was naturally leaning towards the KO2s on 18" wheels. The new truck came with 20" wheels which look good, but, don't offer a very pleasant ride off road due to much shorter sidewall tires. Naturally, I assumed the KO2s were upgraded versions of the KOs. A fellow WTW member and I started trading info. He had installed the KO2s on his F-350 work truck and they were rapidly wearing out around 15K miles!
That got me to doing more research,, and sure enough, BFG, did something to the KO2 rubber recipe that drastically reduced KO2 life span compared to the previous KO version.
All the while I was looking for tires, I was also looking for a 2.5" leveling kit v a lift kit for my new F-350. One of the better after-market suspension component manufacturer is Sage Carli.
Carli Suspension gladly shares a lot of R&D info they develop, including tire information. Most is published on their blog. One of the more interesting things to be discerned from Carli's information, Load E tires, across the size range, perform differently if installed on a 3/4 - 1 ton truck. Heavy trucks, the 3/4 ton and up behave quite differently on tires when loaded vs unloaded compared to the 1/4 and 1/2 ton trucks.
To cut to the chase, Carli found Toyo tires performed better on road and off-road then most all other tires.
Also, Toyo offers more information on tire inflation than any other tire manufacturer (light truck tire chart is the gray/white chart, not blue/white). Toyo recognizes light trucks will carry varying weight loads. Further, Toyo recognizes their LT tires are used under varying conditions and therefore offers plenty of information in their tire inflation charts so you get the front and rear tire inflation psi spot on for your axle weight. Not only does this give you the most compliant ride, it will enhance your tires life span. Simply airing up to the cold temp, placarded max tire psi on the tire or door jam is getting you neither the most comfortable ride or max tire life span. Those placards are lawyer placards so you can not sue the tire and truck manufacturers when things go wrong when you deviate from the placarded information.
Tacoma and half ton truck owners can take advantage of the Toyo tire inflation charts as well. It just that the perceivable difference in laden v unladen psi will not likely be as noticeable as on the heavy trucks.
