What’s worse than a flat tire? The sinking realization that you have no way to fix it. That’s the situation more American motorists may find themselves in as 36 percent of 2015 models are sold without a spare tire, according to new research from AAA. That’s a steep rise from 2006 when just five percent of nameplates omitted a spare. As fuel-economy standards rise to 54.5 mpg for 2025, automakers are desperate to reduce weight and the spare tire is arguably the lowest-hanging fruit. Replacing a spare tire with a four-pound inflator kit can cut as much as 30 pounds from a vehicle’s curb weight, and the donut can be removed without the extensive engineering or major investment other weight-saving technologies require. AAA identified 136 models that don’t include a spare tire as standard equipment, although some of those vehicles do offer one as an option. Every major automaker, from Acura to Volvo, sells at least one car without a fifth wheel and tire. The list is heavy with sports cars, coupes, and hybrids, where space is at a premium, and German luxury cars and crossovers, which often use run-flat tires. (1) The objective of this report is to design a tire mobility kit (TMK) which is a combination of a spare tire, automatic jack and a lug wrench. Why the problem is significant and how it was solved in the past?
