yes, larger can be slower

yes, weight is an issue.. however other factors play a role.

Consider this; equal weigh wheels with the same weight (mass). The 18 will have a larger diameter. so more of it's mass is positioned at a further distance from the rotation point. This increases it's Moment of Inertia. Therefore more Angular Momentum (Torque) is needed to accelerate the larger wheel.

So a larger wheel with the same weight and tire, will accelerate slower when given the same torque.

That being said, a larger tire can usuall accommodate wider tires...
