The Tracompa-2 is Bridgestone's Temporary/Compact Spare tire developed for Original Equipment applications that allow vehicle manufacturers to increase available trunk space and reduce overall vehicle weight compared to using full-size spare tires and wheels. Tracompa-2 tires can help drivers regain temporary mobility in the event of a flat tire due to a puncture, cut, road hazard, accident or blowout.Like all Temporary/Compact Spare tires, the Tracompa-2 tire is designed for temporary use only. It features a smaller physical size, narrower tread, shallower tread depth and lighter-weight construction than the tires with which the vehicle is normally equipped.The smaller physical size requires Tracompa-2 tires be maintained with 60 psi cold tire inflation pressures and driving speeds restricted to 50 mph.Temporary/Compact Spare tires do not include a wheel.Check your vehicle's owner's manual for recommendations and restrictions.
