As a cyclist, you must understand the importance of having well-maintained bicycle tires on your ride. They not only affect your performance but also play a significant role in your safety and comfort on the road. But how do you know when to replace bicycle tires? In this guide, we’ll explore the signs that indicate it’s time for new bicycle tires and provide you with the information you need to make an informed decision.

Before we dive into the signs that indicate it’s time to replace your bicycle tires, let’s address a common question: How many miles do bicycle tires last? Or something related. While some may argue that mileage alone determines bicycle tire lifespan, it’s important to consider other factors that can impact bicycle tire longevity. These factors include bicycle tire type, riding style, road conditions, bicycle tire pressure, and regular maintenance. So, it’s not as simple as stating a specific mileage. With that in mind, let’s move on to the signs that can help you determine when it’s time to replace your bicycle tires.

OK, now let’s head to the part of when you can change your bicycle tires or the signs that can tell you it’s the time to replace your bicycle tires.

The Preparation – Bicycle Tire Anatomy

In this part, we will check and learn some basic bicycle tire terms first, which you will see in the following words,  simply with an image. It is quite easy. And writing this part, it is in case that some cyclists may have not known these bicycle words yet, or to make sure that we are talking about the same thing since people may have many different names for the same part.

8 Signs Indicating When to Replace Bicycle Tires

Here in this part, we will cover 8 signs which can tell you whether a bicycle tire should be replaced.


One of the first signs that your bicycle tires may need replacing is the presence of cracks. Cracks are small fissures or splits in the rubber of the bicycle tire that can appear on the tread or the sidewall. They are caused by exposure to sunlight, heat, ozone, or chemicals, as well as the natural aging of the rubber compound.

Inspecting your bicycle tires for cracks is essential, as they can reduce the elasticity and strength of the bicycle tire, increasing the risk of blowouts or flats. Cracks can be a little challenging to spot with the naked eye, so it’s a good idea to use a magnifying glass or a flashlight to inspect your bicycle tires carefully. And here are some useful tips to help you make the decision for different situations of cracks on the bicycle tire.

If the cracks are small and superficial, affecting only the surface of the rubber, they may not pose an immediate threat to the bicycle tire’s performance and safety. However, it’s important to monitor them regularly and avoid exposing them to harsh conditions that may worsen the cracks.

On the other hand, if the cracks are large and deep, reaching the inner layer of the bicycle tire, they can compromise the bicycle tire’s integrity and increase the risk of air leaks, blowouts, or loss of traction. If you notice such cracks, it’s the proper timing when to replace bicycle tires.

Sidewall cracks are particularly concerning, as they can weaken the bicycle tire’s structure and make it more vulnerable to damage from road hazards or impacts. Sidewall cracks can also affect the bicycle tire’s pressure and stability. If you see any sidewall cracks that continue to grow in length, depth, or number, it’s time to replace your bicycle tire.


Another telltale sign that it’s time to invest in a new set of rubber is about the cuts on the bicycle tires. They can be deep slashes or gashes in the rubber of the bicycle tire that can penetrate the casing or the inner tube. Cuts are usually caused by sharp objects on the road, such as glass, metal, rocks, or thorns.

To check for cuts, simply look at the surface of your bicycle tire or feel it with your fingers. If you spot any deep cuts that expose the internal layer of the bicycle tire, it’s time to replace it. This layer helps protect against punctures and maintains the shape of the bicycle tire.

Another thing to consider is the size and location of the cut. If the cut is large enough to allow foreign materials to enter the bicycle tire and puncture the inner tube, causing a flat, it’s definitely time to replace the bicycle tire. Similarly, if the cuts are numerous and cover a large area of the bicycle tire, especially in the tread or sidewall, it’s a clear sign that it’s time for new rubber.

However, not all cuts require immediate replacement, especially for those that are small and shallow. Depending on their size, location, and depth, there are a few methods you can use to deal with minor cuts:

1. Tyre Plugs: These small strips of rubber or synthetic material are inserted into the cut to seal it and prevent air leakage. They are usually used for small cuts in tubeless bicycle tires.

2. Tyre Boots: These patches of rubber or fabric are glued or taped to the inside of the bicycle tire to cover the cut and reinforce the bicycle tire structure. They are usually used for larger cuts in the tread or sidewall of the bicycle tire.

3. Stitching: This method involves sewing the cut together with a needle and thread. Stitching is used for deep cuts that go through the bicycle tire casing and expose the inner tube.


Abnormal protrusions or swellings on your bicycle tire, known as bulges, are a clear indication that something is wrong. These bulges can appear on either the tread or the sidewall and are caused by damage to the casing or inner tube, such as tears, holes, or separations.

The structural integrity and stability of your bicycle tire can be compromised by these bulges, which increases the risk of blowouts or flats. To check for bulges, simply inflate your bicycle tire to the recommended pressure and look for any irregularities. A small bulge near the valve might be a result of improper installation or inflation and can be fixed by deflating and reinflating the bicycle tire correctly.

However, if you spot a large bulge anywhere on the bicycle tire, it may indicate serious damage or defect, and it’s crucial to replace the bicycle tire as soon as possible. A bulge can also cause frequent flats by exposing the inner tube to sharp objects or creating a weak spot that can burst under pressure. So, if you’re experiencing flats more often than usual, especially in the same area as the bulge, it’s definitely time to consider a bicycle tire replacement.


Punctures are another common issue that can affect the tread or sidewall of your bicycle tire. These small holes or perforations are typically caused by sharp objects on the road, such as nails, screws, pins, or needles. Punctures can lead to air loss from the bicycle tire or flats in the inner tube, leaving you stranded on the side of the road.

Detecting punctures can be tricky, as most of them may not be visible to the naked eye. To check for punctures, use a spray bottle filled with a mixture of water and soap. Spray the solution onto the bicycle tire and look for any bubbles forming. If you see bubbles, it’s a clear sign of a puncture that needs to be addressed.

When it comes to punctures, prevention is key. Consider investing in puncture-resistant bicycle tires or adding bicycle tire liners or sealants to minimize the risk of punctures. However, if you find yourself dealing with frequent punctures despite taking preventive measures, it may be time to replace the bicycle tire. Multiple punctures in a short period can weaken the bicycle tire’s structure and compromise its performance.

Tread Wear

Tread wear refers to the loss of rubber material from the surface of the bicycle tire. This wear occurs due to friction from braking, cornering, accelerating, or riding on rough surfaces. As the tread wears down, the bicycle tire’s ability to grip the road diminishes, increasing the risk of skidding or sliding.

There are a few ways to check for tread wear on your bicycle tires. The most accurate method is to use a tread depth gauge, which measures the depth of the tread. If the tread depth is below the recommended minimum, it’s time to replace your bicycle tires.

Another way to check for tread wear is to look for tread wear indicators. These are small grooves or dots that are embedded in the tread pattern of some bicycle tires, such as Continental or Schwalbe. These indicators serve as a visual cue, indicating the minimum tread depth required for safe and optimal performance. When the rubber has worn down to the level of these indicators, the bicycle tire has reached its wear limit and should be replaced.

If the tread pattern or knobs on your bicycle tires are worn down or flattened, it’s also a clear sign that the bicycle tire needs to be replaced. A smooth surface reduces the grip and traction of the bicycle tire, especially on wet or loose surfaces.

Sidewall Damage

The sidewalls protect the bicycle tire from external impacts and abrasions and play a crucial role in maintaining the bicycle tire’s shape and integrity. Sidewall damage can occur due to a variety of factors, including: rubbing against curbs, potholes, or debris on the road, underinflating or overinflating the bicycle tire, which puts excessive stress on the sidewalls, etc.

To check for sidewall damage, visually inspect the side walls of your bicycle tires. Look for any scuffs, scrapes, dents, or wrinkles. These are signs of sidewall damage that can weaken the support and shape of the bicycle tire, increasing the risk of blowouts or flats.

Excessive Flats

If you find yourself constantly dealing with flat bicycle tires, even after repairing them, it may be time to invest in new bicycle tires. Frequent flats can indicate that your bicycle tires have become too worn and are no longer providing adequate protection against punctures.

Excessive flats can indicate that the bicycle tire is worn out, damaged, or improperly inflated, which can no longer provide adequate protection against punctures and thus affect its performance and safety. If you find yourself constantly dealing with flat bicycle tires, even after repairing them, it may be time to invest in new bicycle tires.

But things may not be that simple. Here are some tips on how to use excessive flats to help us identify when to replace a bicycle tire:

If the flat occurs on the same spot of the bicycle tire repeatedly, it may mean that there is a sharp object embedded in the bicycle tire or the rim that is puncturing the tube. You should inspect the bicycle tire and the rim carefully and remove any debris or foreign objects.

If the flat occurs on different spots of the bicycle tire randomly, it may mean that the bicycle tire is underinflated or overinflated, which can cause the tube to burst or pinch. You should check and adjust the bicycle tire pressure according to the manufacturer’s recommendations and the riding conditions.

If the flat occurs on both bicycle tires frequently, it may mean that the bicycle tires are old or of poor quality, which can make them more prone to flats. You should check the age and condition of your bicycle tires and replace them if they are beyond their expected lifespan.


Even if your bicycle tires appear to be in good condition, it’s important to consider their age. Over time, the rubber compounds in bicycle tires degrade, which can lead to decreased performance and increased vulnerability to punctures.

How to Postpone the Replacement of A Bicycle Tire

Bicycle tires are more prone to wear and tear than most other parts of a bicycle. And each bicycle tire may cost you dozens of dollars. For a bicycle part which needs replacing periodically, that would be a lot of money, seriously.

So only showing you the signs to replace a bicycle tire is not enough, to my understanding, the more important thing is telling you how to make each bicycle tire run longer, thus helping you save some money.

Here in this part, you will learn about two methods, which I have personally tested and apply to my daily riding, and many other cyclists love, too, to prolong the lifespan of your bicycle tire, but not sacrificing the riding quality.

1. Rotate Your Bicycle Tires

Bicycle tire rotation involves swapping the front and rear bicycle tires periodically. The goal is to even out the wear patterns caused by different forces acting on each wheel. The front bicycle tire, for example, experiences more of the braking force, while the rear bicycle tire carries most of the rider’s weight.

By rotating your bicycle tires, you can ensure that both bicycle tires wear evenly and last longer, preventing one bicycle tire from wearing out faster than the other. This means you can get more mileage out of your bicycle tires, saving you money in the long run.

Besides, unevenly worn bicycle tires can affect your bicycle’s handling and stability. By rotating your bicycle tires, you can ensure that both bicycle tires have similar levels of grip and traction. This can enhance your overall riding experience and make your bicycle feel more stable on the road.

Now let’s dive into the step-by-step process of how to rotate your bicycle tires.

Step 1: Remove Both Wheels from the Bicycle

To begin, you’ll need to remove both wheels from your bicycle. Follow these steps:

  1. Release the brake and loosen the axle nuts or quick-release skewers that hold each wheel in place.
  2. Lift each wheel out of the fork or frame dropouts. For the rear wheel, make sure to shift the chain to the smallest cog on the cassette before removing the wheel.
  3. Place both wheels on a flat surface with the valve stems facing up. This will make it easier to swap the bicycle tires later on.

Step 2: Swap the Front and Rear Bicycle Tires

Now that you have both wheels removed, it’s time to swap the front and rear bicycle tires. Here’s how:

  1. Deflate both bicycle tires completely by pressing down on the valve stems until no air comes out.
  2. Break the bead of each bicycle tire from the rim by pushing down on both sides of the bicycle tire with your thumbs or palms.
  3. Use bicycle tire levers to pry one side of each bead over the rim edge and hook them onto the nearest spokes.
  4. Slide the bicycle tire levers along the rim edge until one side of each bead is free from the rim. Remove the levers carefully.
  5. Pull off one side of each bead from the rim using your hands or a third lever if needed. Leave the other side of each bead on the rim.
  6. Push the valve stems through the rim holes and pull out the inner tubes from inside the bicycle tires.
  7. Swap the front and rear bicycle tires by placing them on the opposite rims. Make sure that the label of each bicycle tire is aligned with the valve hole of each rim and that the direction of rotation of each bicycle tire is correct.
  8. Tuck in the inner tubes inside the swapped bicycle tires using your fingers. Make sure that the valve stems are perpendicular to the rims and that the inner tubes are not twisted or kinked inside the bicycle tires.
  9. Place one side of each bead over the rim edge and push it into the rim groove using your hands. Start from the opposite side of the valve hole and work your way around to both sides of the valve hole.
  10. Place the other side of each bead over the rim edge and push it into the rim groove using your hands. Start from one side of the valve hole and work your way around to the other side of the valve hole. You may need to use a bicycle tire lever to pry over the last part of the bead if it is too tight. Be careful not to pinch the inner tube or damage the bicycle tire.

Step 3: Install Both Wheels on the Bicycle

With the bicycle tires swapped, it’s time to reinstall both wheels on your bicycle. Follow these steps:

  1. Reverse the steps that you took to remove both wheels from the bicycle.
  2. For the front wheel, simply slide the wheel into the fork dropouts and tighten the axle nuts or quick-release skewers. Then, reconnect the brake and check that the wheel spins freely and the brake works properly.
  3. For the rear wheel, place the chain on the smallest cog on the cassette before sliding the wheel into the frame dropouts. Then, tighten the axle nuts or quick-release skewers and reconnect the brake. Check that the wheel spins freely, the brake works properly, and the chain shifts smoothly.

2. Store Your Bicycle Tires Properly

When not in use, bicycle tires are susceptible to various factors that can cause damage over time. Sunlight, heat, ozone, moisture, and pressure are the main culprits that can lead to cracks, deterioration, or a decrease in bicycle tire quality. By storing your bicycle tires correctly, you can extend their lifespan, maintain their performance, and avoid unnecessary expenses down the road.

Best Practices for Storing Your Bicycle Tires

1. Avoid direct sunlight: Store your bicycle tires in a cool and dark place to protect them from UV rays. A basement, garage, or closet are ideal storage locations. Additionally, cover your bicycle tires with a cloth or a bag to block out any light.

2. Keep them away from heat sources: Store your bicycle tires in a cool and dry place, away from radiators, heaters, or fireplaces. This will prevent them from softening or melting due to excessive heat. Regularly check and adjust the bicycle tire pressure to prevent underinflation or overinflation caused by heat.

3. Choose a well-ventilated storage area: Ozone can be damaging to your bicycle tires, so store them in a well-ventilated place. Keep them away from electric motors, generators, or appliances that produce ozone. Consider using a bicycle tire protectant or rubber conditioner to coat your bicycle tires and prevent ozone exposure.

4. Keep them dry: Moisture can lead to rust, corrosion, or rot in your bicycle tires. Before storing them, wipe off any dirt or water from the bicycle tires. Store them in a dry place, away from water pipes, sinks, or showers. Consider using a dehumidifier or a fan to reduce the humidity level in the storage area.

5. Store them at a moderate pressure: When not in use, store your bicycle tires at a moderate pressure level. Follow the manufacturer’s recommendations for the optimal bicycle tire pressure for your specific bicycle tires. Regularly check the pressure with a gauge and adjust it if necessary. Avoid storing the bicycle tires on the ground or under heavy objects that can deform them.

By following these best practices, you can ensure that your bicycle tires stay in top-notch condition even when they’re not in use.


We have just finished uncovering the secrets of the appropriate timing when to replace a bicycle tire and more importantly sharing some ideas to protect your bicycle tires and make sure they can run for more miles.
