KO2 or KM3
I had run both on my 18 Jeep JLUR.
Factory tires were 33" ko2`s then I went up to 35" KO2`s
I finally stopped at 35" KM3`S. I liked the look of a more aggressive tire after wasting money on the 35" KO2`s that looked basically like a 33" KO2
I was at the yearly Jeep invasion in Wildwood NJ and ther were over 1200 Jeeps there running any tire you could imagine. They have a street run where they can do a main street drive at roughly 25mph. It was a perfect way to see what you liked or disliked, listen to tires at that speed and if you liked the tire you found the Jeep and talked to the owner`s to get the real scoop on how they performed. Super Swampers to Military tread.
Here`s what I found while running them on a lighter Jeep. They were loud, not killer loud. They broke lose real easy on the dry street, I had a Rubicon V6 gas, 8 sp. auto and 4:11 gears.
I had to remember to slow down a little earlier on wet roads.They eat snow and mud and throw them up with ease. They bit hard on rocks when crawling and I know I`m forgetting other things about them. I can`t remember if they were the lightest 35" mud tire out there. There are plenty of websites to compare every aspect of tires including side by side comparisons
To play around with size and offset and how they would actually fit and stick out or even hit. willtheyfit.com and tiresize.com
They were a little hard to balance and had to be rotated on the rims several times to get the least amount of weight on them.OK 4WD in NJ did the mounting and they are a serious off road shop that has been around for 30 years.
I had played around with tire pressure just like any other tire. I did the chalk test to help get the right tire pressure for the street.
I can also say how using bags of Ceramic beads worked for me trying to balance tires. I will try to remember who the manufacture was, I do remember they are one of the oldest and largest ones.
I hate to say it but there is a TON of information on tires on the JLWranglerforums.com along with info on lights and all other parts that you would consider a universal fit
I hope that this helps you out a little
