If you put the wrong tire size on your 22's then it can feel sluggish. As well if the wheels are heavier or as heavy as the factory ones they can cause slugishness. This is due to 3 reasons:

1. Rotational weight is equal to about 3x stationary weight, so a heavier wheel will require 3x the power to move compared to adding normal weight to the car.

2. The further the weight is pushed AWAY from the hub (IE a 22" rim vs an 18" rim) the more energy is required to move it.

3. A larger OVERALL diameter of the tire/wheel combo can effect the "final drive" of the car. If the wheel/tire are larger than factory size then the car is effectively "geared up" so it feels like your driving the car in 1 gear higher than it should be. Similarly if you decrease it it'll gear down and feel like your 1 gear lower.
