I don't know anything about Rhinos, but basic tire/wheel principles apply to all vehicles. First off tires and wheels (plus a-arms, brakes, etc) are 'un-sprung' weight. In other words they are not being held up by the shocks/springs. The lighter the un-sprung weight, the better able the vehicle is able to react to bumps and steer. You can thank Sir Isaac Newton for figuring all of this out. Next is reciprocating mass; the heavier the wheel the more reciprocating mass. And where this mass is in relation to the center axis is also important, but that is another story. Sooo...what this means is the heavier the wheel/tire combo is the slower the vehicle will accelerate and slower it will stop. Heavy wheels and tires are much harder on brakes, CV's, axles, diffs, etc. But in most cases more 'material' (eg weight) the more durable the package is. What all this crap means to you is you need to come up with a good balance in a tire/wheel package that is durable enough so you don't get flats and break wheels, but light enough to have a good handling rig that doesn't put undue stress on other components. My recommendation is either Walker Evans or OMF wheels and Maxxis tires. My dos pesos!
