Automakers ditch spare tires in more new car models

Nearly four in 10 new cars are sold without a most basic feature the spare tire.
A study by the American Automobile Association, or AAA, found that 36 percent of 2015 models come with run-flat tires or tire inflation kits instead of a spare tire. That's up from just 5 percent in 2006.
Flat tires are not a disappearing problem, but spare tires are, said John Nielsen, AAA's managing director of Automotive Engineering and Repair. AAA responds to more than 4 million calls for flat tire assistance annually and, despite advances in vehicle technology, we have not seen a decline in tire-related calls over the last five years.
It's a trend that cuts across all segments of the auto industry. Cars sold without spares as standard equipment include the Hyundai Elantra and almost all BMW models.
The Auto Club wants car companies to equip all their new vehicles with spare tires.
Automakers are removing the spares to save money and trim weight to improve efficiency as they face increasingly stringent fuel economy standards. Trading a spare tire for an inflation kit removes about 25 pounds from the car.
They are also eliminating the spare tire well to increase usable interior space in downsized vehicles as well as to improve the aerodynamics of the underside of the vehicle for better mileage, said Megan McKernan, manager of the Auto Club's Automotive Research Center.
But these aren't good trade-offs for consumers, the AAA said.
Tire inflation kits have limited use and are often unable to provide even a temporary fix for many common flats. They can cost up to $300 to replace and only last four to eight years, depending on the manufacturer, AAA said.
The Auto Club tested the most common tire inflation kits. It found they work only when a tire is punctured in the tread surface and the object remains in the tire. The kit then coats the inner wall of the tire with a sealant and a compressor re-inflates the tire.
They don't work if the puncture-causing object has fallen out, creating a larger hole, or when a sidewall is damaged or a blowout occurs. Those situations will require a tow.
The reality is these kits can accommodate specific types of tire damage, but having the option to install a spare tire can save stranded drivers time and money, Nielsen said.
 
The weight savings is a bogus claim. 25 lbs. on a 3,000 lb. car? Pffft.

Making more room for space in the car is a more legit claim. Especially in sedans and coupes with limited cargo space (called a trunk).

I figure many new drivers don't know how to change a tire or want to get their hands dirty anyway, so for them it doesn't matter. They'll just call roadside service or have a "Safe Clear" type of tow truck get them.
 
I get this. I've been seeing this on more and more newer cars. It made me wonder if half of the people who buy cars even know where their spare tires are, or even how to change them. I guess most people would just rather pay for roadside assistance.
