Why Do I Keep Getting Punctures Road Bike

As a passionate road cyclist, there’s nothing more frustrating than getting a flat tire in the middle of a ride. Not only does it put a damper on your workout, but having to constantly replace tubes can also be costly and time-consuming. This is a common issue faced by cyclists of all levels, and there are a variety of reasons why it may be happening to you.

Why Do I Keep Getting Punctures on Road Bike?

You could keep getting punctures on your road bike due to sharp objects repeatedly hitting your tire, over or under inflation, poor maintenance, or a worn out or dry tire/tube.

While punctures can be frustrating, it’s important to remember that they are a normal part of cycling and can often be prevented with a little preparation and common sense. [1]

#1- Sharp Objects

When something sharp like glass or a thorn pierces the rubber of the tire, it can cause the inner tube to deflate, leaving you stranded on the side of the road.

#2- Over or under Inflating Tires Causing Punctures

One common cause for repeated punctures on a road bike is over or under inflating the tires. If you have a very low pressure in your bike’s tire, the tire is more susceptible to pinch flats, where the tube gets sandwiched (and eventually squeezed) between the hard road rim and the rim.

On the other hand, if the tire pressure is too high, the tube can explode just like an overinflated balloon.

This can occur when the tire isn’t properly installed on the rim or when the bike takes hard impacts, making it more likely to blow out.

Furthermore, if the tire and rim don’t seat correctly, the tube can become pinched between the tire and rim, leading to punctures.

It is important for riders to regularly check the recommended tire pressure and adjust it as needed to prevent these types of punctures. [2]

#3- Not Checking the Tire Properly

Sometimes punctures are caused by small sharp objects like flint, glass, or thorns, that poke through the tire and pierce the inner tube.

However, some punctures can be avoided by thoroughly checking the tire before replacing the inner tube.

It is extremely wise to check where the valve is in line with the writing on the tire, then pumping up the damaged tube to locate the snag while running the tube along the hand to find the hissing area.

It is essential to locate and remove the lodged object before fitting a new or repaired tube to avoid quick deflation. [3]

Without properly checking the tire, it’s easy to miss the sharp objects and end up with yet another puncture shortly after replacing the inner tube.

To avoid this, it’s important to carefully inspect the inside of the tire and remove any sharp objects before replacing the inner tube.

Running your fingers along the inside of the tire can help you locate the culprit. Taking the time to check your tire properly can save you from the frustration of getting a puncture on your next ride. [4]

Tips to Avoid Road Hazards Like Glass

When it comes to avoiding punctures on a road bike, one of the most important tips is to avoid riding over glass on the road. This may seem obvious, but many riders still make the mistake of riding through glass.

Instead, try to go around it or even point it out to other riders if you’re in a group.

It’s also crucial to replace worn-out or badly cut tires, as these greatly increase the chances of getting a puncture.

Before heading out for a ride, it’s recommended to check for any embedded glass fragments in the tires and remove them.

It’s also a good idea to replace inner tubes yearly, and make sure that tires are properly inflated to avoid pinching the inner tube on a pothole.

By following all these tips, a cyclist can significantly reduce the risk of getting a puncture on their road bike. [5]

Importance of Replacing Worn-Out or Badly Cut Tires

One of the top ways to avoid bicycle punctures is to replace worn-out or badly cut tires. It may seem obvious, but many cyclists neglect to do so and end up with multiple punctures. When a tire is worn out or has deep cuts, it greatly increases the chance of getting a puncture.

Any cut that has gone right through the tire to the inside is a cause for concern. At times, you may get a really bad cut in the tire after just a week of use, and replacing it is the best way to prevent future punctures.

Remember, this is probably one of the best ways to avoid bicycle punctures.

Tools & Techniques for Fixing Punctures

There are several tools and techniques for fixing punctures that every road biker should know about.

One of the most important tools to carry is a spare inner tube and a tire lever to remove the tire.

Before removing the damaged inner tube, a simple method is to locate the puncture by pumping air into the tube and listening for the hissing sound.

Once the puncture is located, use a patch kit to repair the puncture, or simply replace the inner tube with the spare one.

Another option is to carry sealant, which can be easily added to the tube to prevent future punctures.

Additionally, using puncture-resistant tires or going tubeless can be effective in preventing flat tires. Having these tools and techniques can make a difference between enjoying a ride and being stuck on the side of the road. [6]

When to Replace Inner Tubes

Generally, it’s a good idea to replace the inner tube if it’s been punctured. However, it’s also important to check for wear and tear over time.

Inner tubes can become brittle and crack, especially if they are exposed to lots of sunlight or heat. If the inner tube has any cracks, it’s time to replace it.

Additionally, if the valve stem is damaged or the tube has been patched multiple times, it may be time for a replacement.

It’s also important to make sure that the proper size of tube is being used for the tire. Using the wrong size can cause pressure issues and increase the likelihood of punctures. [7]


By taking simple precautions such as checking the tire before replacing the inner tube and being mindful of road debris, a cyclist can reduce their risk of getting a flat. Being vigilant and taking care of the bike can go a long way in reducing the number of punctures a rider experiences. So, don’t forget to check those tires before hitting the road and always be aware of the road conditions to stay safe and have a pleasant riding experience.
