I went ahead and ordered Toyo Open Country in 255/65/18. Toyo says those are 31.1". I had them on a TRD Pro 4Runner in the past and liked their on-road and off-road characteristics.
I'm guessing with the lift I'll be just fine, but I guess we'll see!
Awesome info, dreadlocks. Ideally, looking at that tire OD and maybe nominal width is the real answer. I think I'm going to look at something like 31" tall to be safe with my 2" lift.
Who wants to talk tires? 54 pages of replies, I'm sure there's some gold in there I missed...
Driving a 2014 Cayenne Diesel, steel suspension. Adding a 2" lift as well as spacers that will give me about 20mm extra clearance over stock along with 20mm fender extension to keep the look flush...
