Toyo and General (not all models) were the ones that came up most often as close to 35". I almost went Toyo but they were all order to ship in my area so I also wanted something I could find fast just in case. Of course I have never actually had an issue with any of the BF Goodrich tires I have owned so probably not a big deal. I've also had good luck with General. I had to get rid of a set of Bridgestone Duelers on my Scout due to age, so again another good tire. Same thing with Michelin's on my Discovery II. Actually, most modern tires are pretty good compared to my Co-Op Grip Spurs I ran in high school. Of course if I could get them now I would most definitely run them on the Scout again, even with the 10K life span and rolling like a brick every morning for the first 10 miles.
I have run BFG KO tires for several sets on my older full size 4x4 pickups, but not the KO2. I like the 34.4" tire height of the 315 70R17 BFG KO2 due to when it's fully inflated I have read that it will still tightly fit underneath in the spare location on the latest model Power Wagons.
However, my issue with the KO2 is not the height of the tire, but the tread depth. I am quite familiar with the tires. I have purchased the KO2 tires for my daughter's Jeep, but stopped short of purchasing them for my pickups. My son ran the KO2 on both his Ram 2014 2500 and his Tacoma. I worked with him in dealing with tire balancing issues of a new set of KO2 tires of which the tire dealership didn't stand behind. We went to many tire dealerships other than the one that they were purchased at and they stated that they were unable to get the tires balanced. After that I purchased a set for my daughter's Jeep with no issues, other than it being totalled soon afterwards when the tires lost their grip. It was not the fault of the KO2 tires, but the driver's speed in the extreme cold (minus 46F) and poor winter road conditions near Gunnison, Colorado.
Anyhow, I still wanted a deeper tread depth than the KO2 for my full sized pickups.
The KO tires had a 1/2" tread depth, but their latest KO2 tires are just 15/32". My travel trailer tires tread depth were even deeper when new at 1/2". Both living and driving across state lines in snow during the winter I would prefer to start out with at least a 1/2" tread depth when new in order to get some useful wet traction life out of the tires. When the tires wear down to a 6/32" tread depth they aren't too good in deep snow and it's time to think about replacing them.
At least one western state has a 6/32" tread depth as their minimum requirement in snow without the use of chains. There are plenty of new 18/32" plus tread depth on 35" tires available. A deeper tread depth for driving in both mud and deep snow never hurts when it comes to wet road traction.
