Car manufacturers increasingly provide expensive run-flat tires instead of spare

Imagine your tire blows out on the highway and instead of waiting for roadside assistance, you decide to change the tire yourself.

If you drive a new vehicle, you get a surprise when you open the trunk: no spare tire.

Once standard in cars, trucks and SUV, spare tires are starting to disappear, whether people know it or not.

Pete King loves his new Chevrolet Volt because it's gas and electric and is very fuel efficient. But he can't help but notice something's missing: a spare tire.

"Instead having one of these," said King, who was given an air pump and tire sealant. "It's like a Fix-a-Flat."

Nixing the spare tire is a big trend now. A growing number of vehicles from almost every manufacturer are now rolling out without them.

(See AAA's list of cars without spare tires.)

The companies say it creates more trunk space, reduces vehicle weight and helps you get better gas mileage.

But experts say it could cost plenty if you get stuck on the side of the road.

"Somebody came in and they had a flat tire and they had to have it towed in," said Aaron Nelson, who owns Aaron's Car Care in Jacksonville. "And I said: 'Well, put your spare on it.' They didn't have a spare."

Nelson says more and more of his customers don't even know their new rides don't come with the old-fashioned safety nets. Instead, he says many new models come with inflator and sealant kits or run-flat tires which are designed to go at slower speeds for 50 miles or more after a tire has been punctured.

"Once you get to that point, you need a tire," said Nelson. "There is no fixing it. Because once it has been run flat, it is done."

Because once it has been run flat, it is done."

That could be expensive because run-flats generally can't be fixed and they cost more than regular tires. Prices can reach several hundred dollars a tire. So consumer groups like Angie's List have been trying to educate drivers.

"For most having a flat tire can be their worst nightmare, especially if they are caught on the road when it happens," said founder Angie Hicks. "Being prepared and knowing exactly what you've got when shopping for a car is going to be important. Don't be afraid to ask the dealer, what comes with the car? How does it work?"

I have a car without spare tire, just sealant and air pump where spare tire used to be housed. When I went to dealership 1.5 years ago to purchase a new car I was surprised to see there is no spare tire. My first thought was, no way I'll buy this car without spare tire or jack but after thinking about it for a while... I have never had a flat tire that was not my fault in my 20 years of owning any vehicles. I always be sure to do proper maintenance, rotate and balance tires and replace tires before they are too worn. Also technology is much improved these days. So, I decided to go ahead and purchase it without the spare tire. 60,000 miles later and 4 new tires, I'm still going.. Have not had to use the sealant or air pump yet, knock on wood! I think we will see a lot more auto manufacturers do same thing in future.
 
My new car didnt have a spare, when I called the dealership to complain they told me to come back in and get one. No problem.
 
Never mind the spare tire, worry about the rims that come on the tire. My son's car is a Mercury Gran Marquis and it has the original steel rims that came with the car. The problem with the rims is who ever made the rims for Ford has the weld that holds the two pieces of the rim together to close to the bead of the rim and missed having the bead over the center of the joint by about 1/16," this causes the rims to crack at the weld and constantly leak air. My son's car has had 3 of the rims crack so far. If not caught you could be driving on cracked rims that could literally separate into two pieces as you drive, causing you to loose control. I have taken the car to the dealer, filed the paperwork for a recall with the federal govt. and neither see's a problem with the rims.
Many other Ford cars use the same rims as was found on the Gran Marquis, including police cars(who have to change their rims every 4 months because of this problem in San Jose, CA). So if you have a Ford vehicle that has a steel rim 225-60R-16 and it continuously looses air, have the rim checked for cracks at the weld. These cars came with a spare tire, but if the spare is cracked and has leaked out all the air, it's not going to be of much good.
 
Cracked rims resulting in air loss? You know there's an inner tube, right? If I had rims penetrating the tube, I'd replace the whole tire configuration. My car didn't come with a spare either, so I used a tire promotion to get it free when I replaced my entire set last year. The mechanic called the fix-s-flat sealant a joke and arranged to give me the free spare instead.

Tubes are long gone, most tires today are tubeless.....
Tubes are so 70's....lol
 
OK so I goofed there. :P So what in the world is holding the air in?

The tire itself, thats why the beads are so strong ( wire windings inside the rubber) and they use a sealant when installing the tires. Todays rims are mainly one piece or 2 piece with the tire mounting surface usually being 1 piece and the center area being pressed in.

tried to find a youtube video but couldnt find anything worthy.

Thanks for enlightening me on that, I try to be on top of things related to cars, then I hear about parts I've never heard before. Now putting modern TIRES on that list! LOL

Well, before long tires wont need air anymore, they are developing foam filled and other geometry related tires for road use. Foam tires are used in military and armored security vehicles but hasnt been made available to the general public yet.

Wow! Just Wow! Another clever idea of increasing MPG on car, eliminate spare tire, viola! half MPG increased... wowowow! save a bunch, but after dealing with flat tire, how much it is going to cost? Probably every penny you saved up from using less fuel, plus more. Eh?

Some things still use tubes ... motorcycle with spoke wheels ... bicycles ... some tractors ... one of the tires on mine has a tube in it since it was cheaper to do that instead of replacing the tire when it got cut ... the fix a flat cans are junk sure it may seal a hole but that stuff will get on the rim too and if the wheel isn't turned when its put in then it could set up in the bottom of the tire and mess the balance up.

Car tires have not had inner tubes in years and you can't even buy a inner tube for a car tire anymore, they can't legally put it in. So yes, if the rim is cracked the tire will leak.

Two piece rims are also illegal now. Too many people were killed by them coming apart.

I've seen cracked aluminum BMW rims.
 
Tubes might still be alive, but it's illegal to put them in a tubeless rim because the rim and tire aren't designed to use a tube and it can have a catastrophic failure causing you to loose control of the vehicle.
 
A friend of mine bought a spare at the junkyard for his new car that had come without one. He's a retired CHP officer and says he would never trust a run flat tire or chance going on a trip without a spare tire. Heck he doesn't even keep his cars after they hit 100,000 miles.
 
I know of only one motorized vehicle that don't carry spare tire for years... Can you guess which one?
