One in Three New 2015 Model Cars Are Missing The Spare Tire

Posted: Updated:

NBC RIGHT NOW -- With the holidays coming up, many of us are planning to travel to see family. But there's a troubling trend in newer model cars you should know about before you hit the road.

According to a AAA report, a third of 2015 model cars have no spare tire at all. Instead they have something else in it's place. 

According to AAA, more than 29 million newer model cars, don't have a spare tire anymore. 

"You may find a kit similar to this in your trunk," Dan Nelson with Perfection Tire said. 

It's called a tire inflator kit. 

"It's going to plug into your cigarette lighter," Nelson said. "It's then going to attach to the tire itself. Most of the kits will automatically fill with the puncture sealant. Then it's simple just turn it on and walk away."

The kit works well enough in emergency situations, but is no replacement for a spare tire. 

"Not in all scenarios will this be beneficial for you," Nelson said. "For instance, if you have a complete catastrophic failure of the tire, you can't repair a tire that doesn't exist."

So why are car companies doing this? 

"Vehicle manufacturers have found a way to reduce weight and obviously cost in not having to produce 5 tires and wheels," Nelson told NBC Right Now. 

Chances are high that if you're driving in a car built within the last 5 years, you only have an inflator kit and may not even know it. With that in mind, we went to a gas station to ask people what they thought of the change.

"Yeah, I was kind of mad and surprised at the same time you know?" Carlos Sanchez said. "I don't think it's right that they're doing that though. I mean taking the spare tires away.>

"I was surprised because what are you going to do if the whole thing blows out and you have nothing and you're stuck there with nothing?" Angel Escobedo said. 

"I didn't even know it existed to be honest. I thought it was silly," Kaya Locati said. "That's just insane."

As for the tire expert, he agrees with every one else. 

"I prefer a spare," Nelson said. 

Next time you're broken down on the side of the road, you might be seeing an inflator kit in your trunk rather than one of these.
