Rim advice (yeah I know...)

Hello, yet again another pointless wheel/tire question. Thinking about stepping down from the 18s I currently have to either 16's or 17's (285-75-16 or 285-70-17) I would like to know the pro and cons of each size rim. Truck is slowly transforming from daily driver to something a little more trail friendly. Seems like 17 inch rims have more options when it comes to tires and both should clear the calipers. Just wanted to get a few opinions. Also if you the idea of another tire / wheel thread feel to say what you will... I imagin I earned it

 

the larger the wheel, the more damage it will attract on the trail.

most of the offroad guys are running 16 depending on the tire size, but unless you do some super gnar stuff, it's basically up to you to choose
