I have had many sets of Kumho's, all being car tires, and would not hesitate to recommend them. I saw the same ratings, and also wonder how they are. I am leaning towards the Pirelli Scorpions tho' 'cuz I like the looks better, but realize the contact patch is waaaay more important than looks. Somebody on here must've tried 'em.....
I have these tires on a ZJ jeep. I like them. a little noisy but nothing bad. I believe mine are 31x10.5. On a 15" rim. I've gone on the beach with them down at 17psi and I've got through a snowy winter and they always got me through whatever I needed to. I recommend them. Cool looking tire too. I can't vouch for bigger sizes tho.
Keep in mind the jeep is a 98 with 170k so it's a little rough and noisy as it is. But happy with my purchase. I think installed I got them for around 600 total after a rebate from kuhmo I purchased from Tire Buyer and had them shipped to an installer
My 05 ram had some Kumho ATs and they lasted onlyb15k miles. I did get a prorated warranty refund though. Maybe I had a bad batch but that's all it took for me to stay away. I'm a big fan of Cooper though.
I see the last post on this topic was on 10/06/2016, but I'm at that juncture right now, deciding on replacement tires.
I've tried the KO2's on my 2012 1500, two years ago. I loved the truck's stance on them, and it's responsiveness, but I did find them a bit more noisy than I preferred, plus I was able to feel minor vibration on the steering wheel. Instead of replacing them, I traded the truck in for a new 2015 :smileup: and after 26M miles, the stock tires are driving whacky.
As mentioned earlier on in this thread, Tire Rack does rate the Venture AT51's second best, next to the KO2's, so I'm thinking trying them, but would like some additional feedback from others who have had them on their RAM.
