What Size Tire?

Ok I'm in need of some tire sizing help. I just bought some 18x8 wheels with the correct offset for the toyota trucks(I think like 40 or 42, don't remember exactly). What size tire do ya'll recommend? This will be going on a bag'd truck with no body drop. 2" Drop spindles in the front and is in the process of being Z'd.

215/35/18

Im goin to be running on 235-40-18 on mine but it will be bodydropped. Oh and they are a 42 offset.
