Conscious needed hard rubber, and it is usually cheaper. I put it on the Suzuki Grand Vitara, the ride is chaotic, then I push it, then I enjoy it. Often I stop at curbs without ulterior motives to slow down if I'm in a hurry. Hard rubber gives, of course, to feel these curbs, but hernias do not crawl out. The tires work well on the primer, forest clearings, and on dry pavement. At the first snow I don’t change, but at the first minus seven or eight degrees of stable I already change, and so the rubber should live longer. Doesn't smell like wear. In short, for this money a very good set of characteristics.
