I have no complaints about the BFG KO2s in E rating, but my truck is heavier than stock. If you're going to get new tires, I'd go bigger than the 65 aspect, and get the 275/70/18s, I think tires are like TVs, you always wish you got the bigger ones after you purchase them! The change in ride, gas mileage etc is negligible and they look better (IMHO) and probably perform slightly better off road. If you are willing to scour the internet for deals, and then go to a place like Town Fair Tire that price matches, you can save hundreds of dollars, I saved a few hundred doing that. But make sure they really balance them well, some places struggle with bigger tires and do the balancing by throwing a lot of weights on, rather than moving them around and you end up with a lot of vibration
