Hard to square this tire company "change them ASAP" marketing stuff with the tread depths that new performance tires (think like "street legal" race tires) come with.
Performance tires aren't going for economy. They come with less tread height because it has better behavior under side loads (turning). And less rolling resistance and marginally less weight.
