At the end of the day it depends what your'e doing.
Hills/forest, bigger 4x4, more ground clearance, lowgear essential, larger wheels, preferably MTR tyres. TORQUE more than power.
Beach, smaller 4x4, ground clearance irrelevant, lowgear nonessential but preferred, ATR/Highway tyres on wide rims for bigger baloon when you psi down. You also want MUCH more -power- than torque.
So what are you going to do?
