36 inch tires can be significantly more heavy depending on the width and brand of the tire. There's more than 15 lbs between a 35x12.50 BFG Mud KM2 and the 35x13.5 Toyo MT. Those of us with 35s might be right at the working limit for the stock steering pump. I've never had an issue and I know the rocks in Moab work out the steering.
True! I have bias TSLs. Some of the trails in WA have a lot of turning............
