Larger wheels in a 4WD configuration do help with ramp climbing, specifically due to their increased ground clearance, but they may also cause issues with your COG because they're raising your drivetrain up so much.
Personally, We're leading towards using 6" wheels in an 8WD because it allows us to build a much lower base in addition to having excellent maneuverability. Also, due to the wheel placement and geometry of the frame, the 8WD should have no problems with climbing the bump.
I'd Imagine with proper wheel configuration one could use as small as 4" wheels and still be able to climb the ramp successfully.
I think we need a little more humour injected into topics such as these to diffuse whatever tension has been created by the original discussion threads. - Travis Hoffman [more]
