Sweet.
How is the onroad noise when you're going say 110kph?
When I had my Patrol I used 31x10.5R15 too, but those were BF Goodrich A/T, when going 110kph I got "some" tyre squeal.
Probably the KJ is better insulated so the noise doesn't go through as much as it did on the Patrol, so I'm interested to know what you've come up with
