I said a positive change not gaining power per say...
You are sure the 19s were lighter then your stock 18s?
Its common knowledge lighter wheel/tire better performance for cornering, accelerating etc.
The circumference of the entire wheel/tire was the same as stock so its not going 2inches larger.. The car dynamics stay the same as far as the height of the tire... But the sidewall gets reduced aiding in cornering and the overall weight of the rim being reduced allows for the power being put to the ground to move the wheel with less overall effort.
Its like saying lift a 50 pound weight and then lift a 30 pound weight... It doesnt mean you are stronger by lifting the 30 pound weight easier it just takes less overall effort to lift. (my best analogy for this situation)
