[QUOTE="Nuzzy, post: 896588, member: 15952"] You also have to consider contact pressure though. If you had a vehicle weight of 4000lbs, you'd have roughly 1000lbs per wheel of contact pressure when all 4 tires are on the ground. Now say you're on some obstacle that requires more traction than 1000 lbs of pressure can overcome (negating for ease any frictional force calculations)... If you pick a tire off the ground during the obstacle, all your weight is divided back on the other 3 thus giving 1333lbs on pressure which may be just enough to hook up and get you over. This of course is assuming you're locked F/R. Yes flex is good, to a point. A flexy open rig will go more places than a non flexy open rig. But a locked f/r is the key and far more important than flex. And sometimes picking tire will give you more friction to get through/over obstacles. :cool: [/QUOTE]
