I can't decide, need some opinions suspension/wheels/tires
 

I have a stock 2014 XLT 4wd and have brand new Nitto Terra Grappler G2 35x12.5x18 tires bought them for another truck that I just sold. I'm using the stock rim an tire for summer use an getting larger winter setup. First part is do I buy 18" rims for these tires while I really like the 17" raptor rim? Second is anybody know how to figure out if I need a leveling kit or not either way? These are the rims I'm looking at.
