Tire sealant can be a quick fix for a leaky tire, but think twice before using it as a permanent solution. Tire sealant can also cause damage to tires.
Different types of flat tires call for different ways to fix them, depending on the situation you're in, the severity of the damage, and the price. If you get a small puncture and not a full blowout, a can of aerosol tire sealant can come in handy — just attach the hose on the product to your tire's valve stem, empty the can's contents into the tire, and keep on driving.
Keeping sealant on hand may offer a quick fix to get your car up and running again. But using it can have drawbacks if you're concerned about tire and road safety. Many automotive brands produce their own tire sealants, so before plunking down some cash for a can, weigh the tire sealant pros and cons.
It's a fast, convenient, and affordable DIY solution. Many tire sealants — think products like Fix-A-Flat or Slime — come in a pressurized can and are easy to apply. When you spray the product into the valve, the tire inflates and the formula coats the inside of the tire, plugging leaks or punctures. Within a few minutes, you can start driving your car so the gel spreads evenly.
Even with more major flats, a good sealant will fill up your tires enough to drive the car a short distance, like to the side of the road. That way, you can get out of the way of dangerous traffic and reduce the risk of harm to you, your passengers, or your wheels. It's a safe option if you don't have a spare tire. Sealant is readily sold in automotive and retail stores, and it's cheap and long-lasting.
Tire sealant may prevent flat tires. Sealants are most associated with fixing tire punctures, but using them for preventing flat tires is often overlooked, according to Marc Lapointe, general manager of Seaway Hyundai in Ontario, Canada.
"Preventative tire sealants are particularly helpful if you live in a more rural area where there is a lot of gravel or rocks, or if you tend to be around job sites, where nails and screws routinely find their way onto the road and driveways," he says. "Using a preventative tire sealant is an easy and affordable way to give the tire an extra layer of protection and help prevent potential punctures that would cost you more money down the road."
Sealant may prolong the life of old tires. Tire sealant doesn't need to be applied only in the event of a flat tire. Jim Wang of Wallet Hacks says that he uses sealant to fill in age- and wear-related cracks in the tires of his farm equipment — a lawn mower, tractor, and wheelbarrow — to keep the items running longer. "The tires themselves are relatively old, have to withstand some rough conditions and so they develop little cracks," Wang says. "A jug of sealant is less than $50, and if it can get a few more years of life out of $500 tires, it's worth it by a long shot."
Tire sealant may damage — rather than fix — your tires. It may be simple to use, but when applied incorrectly, tire sealant may further ruin your tire. Sealant is designed to disperse and fill up puncture holes while aided by the heat of the tire. If it doesn't warm up fast enough, it can pool toward the bottom of the tire and lead to potential wheel misalignment. Tire sealant may also damage the sensors inside your tire, keeping the pressure constant and failing to alert the driver inside the car if the tire pressure was to actually become low.
It's not a permanent fix for a flat tire. Leaky tire sealant has been known to corrode wheels, which can be costly to replace. Plus, no tire sealant is a permanent solution. In fact, you may need to buy a new tire to replace your flat because many service centers won't repair a tire treated with a chemical sealant.
Sealants may contain hazardous chemicals, and removing sealant may be time-consuming for a repair person. Using a canned sealant can increase the pressure inside the tire, too, risking a blowout or injury to the person who's repairing the tire. Sealants may also void your tire's warranty, so that replacement tire will end up costing full price.
Think of tire sealant as an alternative to the spare tire. Only use it in emergency situations, and drive on a sealed tire just to take it to get repaired or replaced. According to CarsDirect, take the precautions when applying sealant that you would when changing a tire, such as ensuring that your car is safely on the curb or shoulder of the road. Depending on the size of your car, SUV, or truck, keep a larger can or multiple cans of sealant in the trunk. Exercise caution when using the applicator, can, and tire inflator, and don't over-apply. Of course, if you've been in a more serious auto collision, prioritize your safety over fixing a tire.

We say yes, since a can of sealant from a reputable auto parts store costs only $5 or $10 and can last months, or even years, when used minimally. For minor puncture holes caught in time, less sealant can mean more and extend the life of the product, and possibly prevent you from plunking down money for a new tire. We would still recommend carrying a spare tire in your trunk, as sealant should be a temporary fix before a flat tire becomes a serious problem.

Monitor journalism changes lives because we open that too-small box that most people think they live in. We believe news can and should expand a sense of identity and possibility beyond narrow conventional expectations.
Our work isn't possible without your support.
About a year ago, I happened upon this statement about the Monitor in the Harvard Business Review – under the charming heading of “do things that don’t interest you”:
“Many things that end up” being meaningful, writes social scientist Joseph Grenny, “have come from conference workshops, articles, or online videos that began as a chore and ended with an insight. My work in Kenya, for example, was heavily influenced by a Christian Science Monitor article I had forced myself to read 10 years earlier. Sometimes, we call things ‘boring’ simply because they lie outside the box we are currently in.”
If you were to come up with a punchline to a joke about the Monitor, that would probably be it. We’re seen as being global, fair, insightful, and perhaps a bit too earnest. We’re the bran muffin of journalism.
But you know what? We change lives. And I’m going to argue that we change lives precisely because we force open that too-small box that most human beings think they live in.
The Monitor is a peculiar little publication that’s hard for the world to figure out. We’re run by a church, but we’re not only for church members and we’re not about converting people. We’re known as being fair even as the world becomes as polarized as at any time since the newspaper’s founding in 1908.
We have a mission beyond circulation, we want to bridge divides. We’re about kicking down the door of thought everywhere and saying, “You are bigger and more capable than you realize. And we can prove it.”
If you’re looking for bran muffin journalism, you can subscribe to the Monitor for $15. You’ll get the Monitor Weekly magazine, the Monitor Daily email, and unlimited access to CSMonitor.com.
