A very simple test, bring ur 17" climb genting hill, see how well the rimsize can help u.
A correct rim size, maximize your grip, acceleration and cornering. Mostly oversized rims are for looks, in a long term they kill your suspension bushing by adding too much weight and inccorect offset, brushing ur inner fender everytime u go over uneven roads n humps, and ur FC will be increased 15% but ur power does not increase.
The conclusion is yours, I speaks based on experience on myself as well shared by others who been through these ordeals.
