A couple things that come to mind:
Regardless of weight, a higher load rating will provide a better safety margin.
Have you verified fitment on that size for the steer axle? Make sure it will clear the fender opening on compression with the wheel turned.
Do you tow anything? You will effect your total final drive ratio with a larger tire, and the result will be very similar to regearing to a high ratio. Generally that's not good if you tow a significant amount. It might put you right where you want to be or might make you bog and then you won't be using OD. When I got my current truck it had taller tires on it and the first thing I did was go back to OE size, although the wheels are 20" and have a great LR. But doing that got my rpms back in the sweet spot and it felt like I had regeared the truck lower.
