The OEM summer-only Pirelli P-Zero tires (Brembo cars) retail for about $350 each at Tire Rack. The G-Max are $194 at Tire Rack. The tread wear rating is 480. That means they aren't very sticky and will last a long time. If you're looking for all-out summer performance, you're gonna find tread wear numbers in the 220 or less area, usually. And those are usually more $. The higher that number is, the longer it will last, the less performance (typically) you'll get. If you have the non-Brembo all-season Pirellis, which I think are 400 tread wear....they will probably be similar in performance.
I drive summer only tires in the summer, and winter only tires in the winter. Kinda makes sense, huh?
