Learn how to fix a flat tire without a spare by using one of these simple, yet effective, solutions
In a previous blog, we went through each of the steps necessary to change a flat tire
. But what do you do when you open the trunk and find that your spare is flat, too? Or what if in a series of unfortunate events, your spare is punctured shortly after you put it on?
No matter what situation you may find yourself in, it's never a bad idea to have another trick up your sleeve; another way to fix a flat tire when a spare isn't available. Fortunately, there are two methods that are simple, cheap, and effective. Read on as we show you what to do if you have a flat and no spare!
Fixing a flat tire without a spare
Imagine this: You're on a road trip with the family (and the dog)
and you stop at the gas station for a much-needed snack. As you walk back to the car, hotdog in hand, you notice something strange on your front tire - it's the dreaded silvery glimmer of a nail. What's more, the tire looks like it's deflating and sooner rather than later, you'll have a full-blow flat.
As the children grow restless and the dog loses its patience, you think through your options. Unfortunately, the spare tire isn't one of them - it's flat, too. Now what? In most cases, roadside assistance would be the best option, but the whole family can't ride in the tow truck to the tire shop and you don't want to leave them with the dog in the parking lot.
Fortunately, you read a blog somewhere that helped you put together a roadside emergency kit
. You fish it out of the vehicle and sift through it to find exactly what you need to get back on the road.
So, what was it you found in your kit that saved the day? There are two main tools you can use to temporarily fix your flat without changing the tire completely (assuming your tire isn't totally ruined): puncture sealant
and a tire patch kit
Finding the leak
Regardless of which tool you have on hand, the first step is locating the puncture site. Of course, this won't be particularly difficult if you ran over something like a nail, but finding a hole in a punctured tire isn't always so easy. To locate the source of the leak, try the following:
First, you can look over the tire to try and find any obvious punctures or foreign objects (like nails).
. If you don't see anything right away, bring your ear close to the tire and listen for a faint hissing sound.
Sometimes, an otherwise invisible puncture can be found by holding your hand just above the tire to feel for the leaking air.
Soap and water.
If all else fails, try the soap and water method. Fill a bucket with water and add dish soap. Then, carefully coat the outside of the tire until it is covered in suds, either by hand or a spray bottle if you have one. Wait for the leaking air to create a small frothy patch of bubbles - you've found the leak! Mark it and then wash the soapy water away.
Of course, if you find yourself with a flat on the side of the road
, you may not have soap, water, and a bucket on hand. However, if you're near a gas station or grocery store, you may be in luck. All you need is a water bottle (or any plastic bottle) and hand soap from a restroom. Simply add the soap to the water in the bottle, shake it up, and gently pour and spread it over your tire!
Now that you've found the leak, let's look at the two most common ways you can fix it.
Use a puncture sealant product
There are a number of different products on the market that can seal a puncture
, and they fall into two main groups. Some brands are a gel-like substance that hardens around the puncture. These products can work well, but they usually require other tools to effectively apply and can be quite messy.
The more common puncture sealant products come in an aerosol can, and don't require anything additional. For our purposes, we'll be focusing on this variant. While the specific directions may vary from product to product, they generally work in a similar fashion.
The aerosol cans typically contain a foam or liquid sealant along with extra air. You attach the can to the tire's valve stem with the tube provided and fill it with the sealant, which presumably covers the puncture from within before hardening. Obviously, these products aren't going to fix major punctures or gashes, but they can be a great temporary solution.
Before using a puncture sealant product, make sure to read the can for product-specific instructions. They'll likely look something like this:
You'll first need to remove any foreign objects, like a nail, with a pair of pliers.
Position the tire with the valve stem at the top.
Attach the nozzle on the can of sealant to the valve stem.
Press the button and allow the fluid to enter.
Although the can comes with a little extra air, you'll likely need to add more air after the sealant becomes firm. Once you've allowed the sealant time to dry, you can use some of your soapy water to make sure it has done its job and stopped the leak.
So how long can you drive with a tire that has been fixed with tire sealant?
Although it depends on the product, some manufacturers say you can drive for up to 100 miles. However, most experienced experts will tell you that that estimate isn't realistic, and it certainly isn't advised. Again, tire sealant solutions are meant to be temporary
, emergency measures rather than a permanent fix. For that reason, you should make a tire shop your next stop.
That having been said, these little cans can be just the thing you need in a pinch. They're small and inexpensive, so you can potentially keep several in your emergency kit.
Use a tire plug kit
A tire plug kit is another tool you can use to temporarily fix a flat until you can replace the tire with a new one. You'll find that there are all sorts of different kits
that range from the most basic tools to a collection of implements for every possible scenario. However, the fundamental components you'll need to plug a flat tire are as follows: a rasp tool, a threading tool, the plug itself, and cement or sealant.
Some of the larger, more extensive kits will come with pliers to remove foreign objects, a knife to trim the excess portion of the plug, and even work gloves to protect your hands while you make the repairs. While you can get by with the basic components, you'll probably want to have the other items at your disposal anyway. If you don't have them in your roadside emergency kit, it's a good idea to find a tire plug kit that comes with all of the above.
First, you'll likely need to remove the tire. This may not be necessary in every case, but you need to be able to have direct access to the puncture point. If your tires are larger, or if the tires take up too much space within the wheel well, you may not have the clearance needed until the wheel is off. For more detailed instructions on how to remove your tire and wheel with a jack and a lug wrench, read our previous blog, "How to change a flat tire in four simple steps.
If the object that punctured your tire is still in place, use your pliers to remove it.
Use the rasp tool to clean the puncture hole. The rasp tool is a long, pointed piece of metal with a rough, textured end. By quickly running it and out of the puncture, it helps make the hole more uniform, cleaning away stray pieces of rubber, but also providing a rough texture for the plug to grip on to.
The insertion tool should look like a long, thin piece of metal with an eyelet at the end (like the head of a really large sewing needle). Thread the plug through the eyelet, and then firmly press the plug into the hole using the insertion tool. Some kits come with a glue, cement, or adhesive product, which you'll want to apply to the plug prior to insertion. Depending on your kit, there should be some portion (like 1/4 - 1/2 inch) of the plug protruding from the hole after insertion.
Cut away the excess portion of the plug using your knife. Then, apply a layer of adhesive over the top to seal it in place and cover any small cracks.
Wait for the adhesive to dry, then apply some of your soapy water to the plug site to test for leaks and fill them in with adhesive if necessary.
Before replacing the tire, inflate the wheel to ensure that the plug and seal holds. If it does, you can now place the tire back on the vehicle, fasten it in place with the lugnuts and finish inflating.
How long can you drive with a tire plug?
Unlike tire sealant, plugs can potentially last for hundreds of miles, or even years after you apply it. Of course, this depends on the plug, the type and location of the puncture, and how well the plug was installed. Furthermore, depending on the cause of the puncture, your tire may be more prone to flats and blowouts in the future.
No matter what the cause of your flat is, or what method you choose to fix it, the safest option is to visit your local tire shop as soon as possible. It can be easy to forget about your tires when you're going through your list of auto maintenance tasks. However, taking care of your tires through routine tire maintenance
is the best way to avoid flats in the future.
