IME, you'll definitely improve an order of magnitude w/each and 2 together. The "giant wheels fad" goes way too far IMO, smaller accelerates better and you'll notice it, in addition to ride quality. A stiff short sidewall is best for cornering, but putting them on oversize rims is counter productive. You also might be able to sell the wheels and tires together. If you were starting w/19s, I'd say just ditch the RFs, but 20's don't really belong on many cars IME and cost performance in many/most (go wider, not taller). That's also the advantage of starting over, you may be able to go a little wider.
