Thanks for your reply. Yeah again, the KO2s are fantastic tires. They're incredibly durable and maybe given the fact that I've rotated them roughly every 6000-7000 miles, have lasted me around 65k miles, which is 15k miles passed the tread life warranty so not too bad. They're also very smooth on the highway with little to no road noise. Granted mine are D1 rated so it might be a different story if you get E rated tires for instance.
I've read that the Wildpeaks have better wet traction than the KO2s but I wasn't sure if that's what people with similar trucks to mine are actually experiencing or not. It just gets confusing because you hear one thing about a tire but then when I asked the sales rep at Discount Tire the other day, he said the Wildpeaks had worse wet traction than the KO2s and that the Ridge Grapplers were better. He also stated that people were getting around 80,000 miles out of the Ridge Grapplers which I personally find very hard to believe for any all-terrain tire.
Mine are the E rated RGs. I would like to add though, I have done some pretty light offroading with my truck. My tires have small chunks missing from some of the tread lugs. I have heard that more serious offroading kills these tires.
Also, in the heat and sun in Az after the first year of owning these tires small cracks popped up between the tread. I went back to discout tire and asked about them and they said that was normal. Which, to be fair, I have not had any issues. But, I was seriously concerned at first. My truck is kept in the garage too so the only time it sits in the sun is at work.
There is absolutely nothing you could do to make these tires last to 80k miles. Guy is full of it.
If you are worried about wet performance I think you should probably stay away from the RGs. I put my truck in 4 auto in the rain because it will spin the tires so dang easy.
