The Spare Tire Retractor

The Spare Tire Retractor, specifically designed for a 2002 GMC Sierra, helps easily retrieve a spare tire from beneath the vehicle. You no longer have to crawl beneath the truck to retrieve a tire, which makes changing a tire a not so dirty task. This device also improves the safety of the individual changing a tire; retrieving the spare tire is quicker, minimizing the time spent on the side of the road. The Spare Tire Retractor was created by students David Morse, Carrie Peterson and Siddharth Vemuri in winter 2003, instructors: Professor Sridhar Kota and Teaching Assistant Charles Kim.
