Of course MANY people have broken with stock tires. Would be interesting to know how much another 1" of tire really would add....Any automotive engineers out there?

I still will rehash.....A Rubicon 44 handles 35-37" tires, a stock 20 year old Montero that came with a P225 handles 35-37" tires, THEN you start with an occasional axle break. So whatever the forces on the Nissan D44, clearly it was under engineered.
