The Radial Spare is Goodyear’s Temporary/Compact Spare tire developed for Original Equipment use on Dodge Ram trucks that allows the vehicle manufacturer to increase available cab/bed space, while reducing overall vehicle weight compared to using a full-size spare tire and wheel. Radial Spare 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 Radial Spare 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 Radial Spare tires be maintained with the cold tire inflation pressure listed on the vehicle’s tire placard and driven at speeds restricted to 50 mph.
Temporary/Compact Spare tires do not include a wheel.
