Hey friends, I I thought I would share my thoughts about my new tires now that I’ve had some time with them. I hope some of you find this information useful.
TLDR - KO3’s are surely more durable for off roading, but the ATP’s are a better all around tire, in my opinion.
Perrelli • I got 42k miles out of the ATP’s that came with my truck. I have a full size spare and was very good about rotating all five tires every 6k miles. I could have gotten more life out of them for sure, but they were chirpy around town and really loud on the highway as they wore down. In that 42k miles, I waded through water almost to the top of the tires for a hundred yards and I had the truck nearly air born in the sand at King of the Hammers. I really enjoyed “spirited” driving on twisty back roads and I did some light rock crawling and wheeling on them. Other than off roading, I ran them at the max pressure (50-53psi) for the entire life. The only complaint I have about these tires is how loud they got as they wore down. I expect the KO3’s to do about the same, but it will take some time to find out.
BFG • In the 4k miles since I installed the KO3’s, I’ve driven in the rain, mud, and snow. No sand yet, but I expect they’ll do very well. These things do really well when traction is limited. I'm very impressed. I’ve done some light wheeling with them and they performed great. I have a low risk tolerance when it comes to damaging my rims while rock crawling, so I don’t push it too hard. In hindsight, that probably negates the reason for going with the KO3’s in the first place, since durability is their greatest advantage over the ATP’s. My range suffered a lot at first compared to the worn out ATP’s, but it got a lot better once I pumped them up to about 75 psi (which gave the onboard compressor a workout). In fact, they are surprisingly efficient now. Not quite as efficient as the ATP’s but really close. I do have a couple complaints about the KO3’s, though. The biggest problem is cornering stability. They just don’t turn in or hold a line like the Perrelli’s did. I drove them really fast on a pot hole filled roller coaster of a road a couple weeks ago. They hop around a lot and easily get upset mid corner. Obviously, that’s not what they were made for, but the ATP’s were much better and always did everything else I asked of them. In my research, I found a few reviewers complaining the KO3’s shake on the highway, despite being correctly balanced. I have the same issue. I can see an obvious shake in the steering wheel if I let it go, but I can’t feel it that much with my hands on the wheel.
In summary, I would buy another set of Perrelli’s instead, knowing what I know now. There is a silver lining, however, because at least the KO3’s are tough and they look really cool.
