I currently run 42 Iroks and 21 spline triples with no issues.... Gonne do some case upgrades before I get the 47s!
As for the Claws they are great street tire! My rig is a trailer rig and sees zero street ever... The 47 LTB is just a better
off road tire, and I believe it does better in the snow than the claw (from what I have seen)
It looks like I am going to give it a go and just build the cases as stronggg as possible....
