Rim size is almost always about looks one la. A smaller rim (unless you need to clear massive brake discs- which you won't unless you've got aftermarket brakes) will always perform better. It's lighter. It's got more sidewall (hence will absorb imperfections better- grip is only maintained if you have your tyres on the road, not bouncing off mid corner bumps. Larger sidewalls also allow for more progressive deformation of the contact patch during cornering- hence more progressive breakaway characteristics). The tyres are cheaper.
