DETROIT—The spare tire has been squeezed out of many new vehicles, thanks to run-flat tires, inflator kits, efforts to reduce vehicle weight and a lack of storage space—especially in hybrids and electric vehicles.
The problem is many drivers don't know their spare isn't there—until they need it, according to a tow truck driver with whom I spoke. He said he is often sent to tow vehicles with flats—and drivers often tell him they were never told that their new vehicles didn't come with spare tires.
Should new-car dealers require salespeople to inform their customers of the spare tire situation?
“I do tell our electric and hybrid-vehicle customers there's a tire inflation kit and not a spare,” said Whitney Phillips, an Internet saleswoman at Bob Maxey Ford in Detroit. “It's something I'd want to know.”
But Phillips said the topic of the spare tire doesn't often come up during purchases. The store, she said, usually orders all of its cars with the optional spare tire. Indeed, several Mustangs on the lot sported window stickers that listed the optional spare tire. Cost: $195.
Generally, the spare tire is overlooked. Many buyers think it is standard equipment.
“Our new 2014 Jeep Cherokee came without a spare of any kind—not even a doughnut. There's an air pump, but big whoop if you shred a tire,” said Maggie Erickson-Stiff, a retired newspaper editor who lives in Palm Bay, Fla.
“Count us among those who assumed. We were dumbfounded. We bit the bullet and bought a full-size rim and tire which, ironically, fits perfectly in the hole where the air pump was located,” she added.
The spare tire issue is big enough to catch the attention ofAAA Inc., formerly the American Automobile Association. A few years ago, AAA began compiling a yearly list of vehicles that no longer come with a standard spare tire—and that includes the temporary mini-spare, or doughnut—as well as the jack and the lug wrench.
That list is now five pages long, with vehicles from nearly every major car maker on it.
Spare tires have been standard equipment on most vehicles for more than a century. In the early days of the auto industry, many vehicles came with two full-size spare tires.
According to the book American Cars 1973-1980, space-saver or doughnut spare tires debuted in the mid-1970s as auto makers sought to reduce weight and increase available trunk space in downsized cars. Now, the mini-spare is giving way to run-flat tires, which can travel around 50 miles without air, or a tire inflator kit, which is useless when a tire's sidewall is punctured.
“We started to hear from motorists and road service providers that they were seeing an increasing number of cars without spare tires,” said Mike Calkins, AAA's manager of technical services.
“A lot of it was spurred by fuel economy regulations, so they (auto makers) can save the 30 or 40 pounds of the jack and spare tire. That can knock a car down in an EPA category. Of course, it saves them money,” he added.
That jibes with what Cadillac's exterior design manager, Brian Smith, said: “Spares are being removed for mass reduction and space efficiency. Why carry around a 40-pound wheel and tire that you may never use? In some cases, exotic, expensive materials have to be used in the structure or powertrain of the car to remove that kind of weight,” Smith said.
Today's tires feature technologies that make them better able to withstand punctures, he said, further reducing the need for spares. “Improvements in run-flat and self-sealing tires are also eliminating the need to carry a spare tire, mini-spare or full size.”
Richard Vaughn, a spokesman for supplier Visteon Corp., pointed out that lugging around a spare tire t likely to be used rarely wastes space and energy.
“Let's look at it from the other point of view, which is that it's a waste of resources—from raw materials to fuel used—to carry around the extra 40 pounds for years, just in case you might need it once,” Vaughn said.
“It's particularly wasteful when one considers that the average person is going to call for roadside assistance anyway.”
About the only vehicles that still have full-size spares are most pickups and large SUVs.
But AAA says drivers are griping so much about the lack of a spare that auto makers are starting to return some type of spare to vehicles.
Honda has equipped all variants of the redesigned 2015 Fit with a spare tire after dropping the feature on the previous model.
“What's happened is that auto makers have gotten a lot of negative feedback about this,” Calkins said. “And what we are now seeing on new cars is that the trend is back to equipping cars with either a doughnut spare or a full-size spare.”
