These came with my car so I'm reviewing them in used condition, but tread life etc. appeared fine when received. They perform ok in the dry at high temperatures, so I would say they are acceptable as summer tires depending on pricing etc. In cold or rainy weather they don't do well, and I would avoid driving on them in cold, rainy weather especially. Car starting sliding on the highway today with them despite driving carefully (rear slide out at about 90mph going uphill in 40F, drizzly weather).
