My local Wal-Mart did an OK job of installation of the tires, but the Douglas tires I purchased left much to be desired. Marginal snow traction, lots of hydroplaning, and they protested loudly when pushed in corners, like highway exit ramps. Then again these were mounted on my Mom's 98 Corolla, which might have been part of the problem! I'd buy tires from Wal-Mart, but avaoid the cheap Douglas models.
