Saw this posted on the SA forum, not sure you all will have seen it, its from an Australian 4x4 magazine
Basically it is a comparison of 31"-33"-35" on a single vehicle to see the difference in approach, ramp and departure angle plus power loss
Tyre......Approach...Departure...Ramp-over....Diff
Size......Angle.........Angle..........Angle.............Clearance
____________________________________________
31"........41deg.......40deg.........16.7deg........220mm
33"........43deg.......42deg.........17.5deg........245mm
35"........46deg.......43deg.........18.4deg........270mm
Power drop at the wheels on Dyno due to increase in inertia of the bigger tyres
31's vs 35's = 13%
Conclusion; Running bigger tyres has more upsides than downsides
