3) The Tire Rack, an online distributor of tires and wheels, conducts extensive testing to provide customers with products that are right for their vehicle, driving style, and driving conditions. In addition, the Tire Rack maintains an independent customer survey to help drivers help each other by sharing their long-term tire experiences (The Tire Rack website, August 1, 2016). The following data shows survey results (one to 10 scale with 10 being the highest rating) for 18 high performance all season tires. The variable tread wear rates quickness of wear based on drivers expectations, the variability dry traction rates the grip of a tire on a dry road, the variable steering rates the tires steering responsiveness, and the variable buy again rates the driver's desire to purchase the same tire again.
