Why Do My Tires Keep Going Flat?
It’s recommended to inspect the tire for any signs of leaks, such as obvious punctures or bubbles. If no visible damage is found, here are a few things to check:
- The valve core is either partially or fully unscrewed.
- There is a leak at the valve stem base.
- The tire bead is not sealing properly.
- The wheel or rim is defective.
- You have poor quality tires.
The tire has a puncture in it.
If you’re running low on air a lot, your tire may have a puncture. To find it, check the tread and sidewall of your tire for something that might’ve caused the flat like glass or nails. Repair kits can be expensive, so it’s cheaper if you can find and fix a small puncture just by covering it with a patch. Sometimes though, it’s easier to just buy another tire altogether and get rid of the old one.
The valve core is either partially or fully unscrewed.
The inner part of the valve stem that leads to the tire is what’s called the valve core. The core is like a little check valve, which means it moves freely in one direction but restricts movement in the other direction. In this case, air can flow out of the tire but can’t flow back into it without some effort.
The first thing to check is if your valve core has come partially or fully unscrewed from its seat. Sometimes you’ll be able to see corrosion on this end of the valve stem, especially if you remove any type of dust cap that may have been on there before. Removing these caps will generally reveal how easily your valves are moving on their own—if they spin freely when there’s no cap closing them off, that’s a sign that they’re not screwed all the way in and are moving around too much inside their hole. If this is the case with one or more tires, you’ll need to tighten those cores back up so they don’t loosen over time and cause further problems down the road (pun intended).
Here’s how: with an open-ended wrench that fits snugly around your core, hold your wheel close to you so you can see inside it clearly. Position yourself so that as you rotate your wheel toward you, gravity helps guide your wrench past each lug nut and onto each valve core evenly instead of randomly shifting around while turning toward yourself blindly without looking directly at what’s happening at all times
There is a leak at the valve stem base.
- Remove the valve stem cap from your tire.
- Take a look at the valve stem base. Is it corroded? If so, you’ve found your culprit; replace the base and replace the cap on your tire’s valve stem to ensure no more moisture gets into it. If there is no corrosion, you have a different problem (see below).
The tire bead is not sealing properly.
The tire bead is the part of the tire that seals it to the rim. The bead can be damaged or defective, resulting in a flat tire. If you have driven your vehicle while the tire was flat on one side, or if you have gotten into an accident where your rim was damaged, then you probably have a damaged bead.
The wheel or rim is defective.
If you’ve experienced a flat tire, you may be asking yourself: why do my tires keep going flat? There are a whole bunch of different causes for this problem, but there is one cause that often gets overlooked: the wheel or rim is defective.
Now, I know that when you hear the word “defective,” you may think we’re talking about your car’s tires. But the truth of the matter is this: an improperly designed or defective wheel or rim can cause all sorts of problems for your car’s tires, leading to premature wear and tear and eventual deflation.
You have poor quality tires.
If you have poor quality tires, the manufacturer should be contacted to resolve the issue. If this happens, it is likely that your tires will need to be replaced by a different brand. The tire warranty should also be checked so that you are covered when the time comes for replacement. If there is no guarantee on the tires or you have used them for more than two years, then they should be returned to either a retailer or directly to the manufacturer for inspection and possible replacement.
you can solve these problems by finding out what they are, then doing something about them.
One of the most common causes of a flat tire is an actual puncture in the tire that is caused by something sharp, like a nail. In order to find this puncture, you’ll need to remove the wheel from the bike and place it in an open area. The best way to do this is by using a flat area like a table or even your kitchen floor.
Next, take out your CO2 cartridge or pump and inflate your tire until it’s at full pressure. This will make finding any leaks much easier. Now you’ll have to look for bubbles in the air. If you see some coming from around the valve stem, then that means there’s a leak at this point; typically replacements for these valves are inexpensive and can be bought at your local bike shop or online. But if it’s not leaking here, then try applying soapy water with a sponge on both sides of your tire and its bead where it meets the wheel’s rim. If you see bubbles form anywhere on the bead, then you’ll know that’s where there’s a leak requiring another tube replacement job.
