When i had the Nitto 265/75/17 installed 31.6 inches I had to cut the trim about 1/2 inche off on the inside were it rubbed. I also have to lift the rear since it rubs when going of road. The Kumo 265/60/18 are only 30.6. so they probably would not rubbed.

will post in my gallery when i have them installed on my stock rims
