Are Tires with Cracked Sidewalls Safe? [Fact Checked]

Cracking on a tire sidewall is a common issue for cyclists and one that needs to be addressed quickly. It can lead to an uncomfortable ride, punctures, and even accidents.

Cracks in the sidewall of your bike tires are caused by wear and tear over time or from hitting objects such as rocks or curbs. The most common cause of cracking is underinflation of the tires which causes them to flex more than they should.

This leads to increased stress on the sidewalls which can eventually cause cracks or splits in them. In order to prevent this from happening it’s important to ensure your tires are inflated correctly, check for any visible signs of damage before you ride, and make sure you replace worn-out tires as soon as possible.

Is It Safe to Drive with Cracks in Tires

Cracks in tires should not be taken lightly, as they can lead to serious safety concerns. It is important to inspect your tires regularly and look for signs of cracking, especially if you have been driving on the same set of tires for a long period of time.

Cracking can occur due to age, improper tire inflation or storage, and exposure to harsh weather conditions. If cracks are found in any of your tires, it is best to replace them immediately as continuing to drive with cracked tires can lead to blowouts or sudden loss of air pressure which can cause a driver to lose control of the vehicle.

Additionally, small cracks in a tire’s sidewall may indicate that the tire has weakened and could fail at any moment – leading again to a loss of control over the vehicle.

Replace Tire If Sidewall Damaged

When it comes to tire damage, the sidewall is one of the most important areas to inspect. If you notice any significant damage, such as a smudge, crack, line, or another localized spot in the sidewall area of your tire, then it is likely that there has been some internal damage that you cannot see.

It is important to replace your tire if this kind of damage has occurred in order to prevent further issues from developing. This type of damage can cause structural weakness and compromise your safety on the road or trail.

Additionally, having damaged tires can reduce overall performance and make for an uncomfortable ride due to increased vibration and instability. For these reasons, it is best practice to always replace a tire with visible sidewall damage.

Replace Tires That Are Cracking

Tires are an integral part of your bike, and any indication that they’re compromised can be a cause for concern. If you notice cracking between the treads on your tires, it’s important to have them inspected by a professional as soon as possible.

This is because the structural integrity of the tire may be at risk, meaning that it could potentially fail while cycling. If the tire is only a few years old, this could also indicate a manufacturing defect that needs to be addressed and replaced immediately in order to ensure safety when riding. Ultimately, if you notice cracks between treads on your tires, make sure to have them checked out by an expert before continuing to use them.

Why Are Your Tires Cracking on the Side

Cracking on the side of tires is a common issue and can be caused by several different factors. All tires are made of rubber, which means that with age and wear, all tires will eventually exhibit some type of cracking condition.

This is especially true when a tire has been in use for an extended period of time. However, this cracking can also be accelerated if the tire is exposed to too much heat or vehicle exhaust, ozone, and sunlight.

Electric generators and motors (that have armature brushes) can also contribute to the premature aging and cracking of your tires. If you notice any signs of cracking on the sides of your tires it’s important to address it quickly as it can cause further damage to the tire itself as well as possibly lead to unsafe driving conditions due to reduced traction or blowouts from weakened sidewalls.

Can Tyre Wall Damage Be Repaired

Tyre wall damage can refer to any type of damage that occurs on the sidewall of a tyre, such as punctures, cuts or abrasions. Tyres are made up of several components, including a steel belt and rubber casing which provide protection against impacts on the road.

The sidewall is the part of the tyre which faces outward and provides additional protection against impacts and other external forces.

While some types of tyre wall damage can be repaired using specialised patch kits, most repairs fall outside what’s called the minor repair area – this is an area located near the sidewall that is not eligible for repair due to its proximity to it.

This means that punctures in the sidewall cannot be repaired since they are too close to it and would compromise its integrity if patched. In these cases, replacing the tyre with a new one is usually recommended as it ensures maximum safety while driving.

How to Glue a Tire Sidewall

GlueTread is an innovative product that has revolutionized the way cyclists approach tire repair. Specifically, GlueTread allows for sidewall repair to be done quickly and easily at home.

This means that instead of having to replace a damaged tire, cyclists can simply glue it back together and continue riding without any further issues.

The adhesive used with GlueTread is specifically designed for this purpose and ensures a secure bond between the tire casing and the rubber sidewall.

It’s important to note that not all tires are suitable for this type of repair, so it’s always best to check with the manufacturer before attempting any repairs on your own. However, if you have a tire that can be repaired with GlueTread, then you can rest assured knowing that you won’t have to worry about replacing your entire tire just because of some minor damage to the sidewall.

What Does Sidewall Damage Look Like

The sidewall of a tire is the portion of the tire between the tread and the rim of the wheel. Sidewall damage can be caused by a variety of things, such as running over a pothole or hitting an object on the road.

This type of damage often results in a bulge or bubble on the sidewall. The bulge or bubble is caused by damaged cords inside the tire due to a severe impact.

These damaged cords are often accompanied by a visible break in the inner liner that allows air to enter into the plies, resulting in an outward bulge or bubble. If you notice any signs of sidewall damage, it is important to have your tires inspected and replaced if necessary for safety reasons.

How Long Should Tyres Last Before Cracking

Rear tyres are usually able to withstand more wear and tear than the front ones,...

The life of a tyre depends on how it is used and stored. Generally, front tyres on a front-wheel drive car should last at least 20,000 miles under normal driving conditions.

Rear tyres are usually able to withstand more wear and tear than the front ones, so they may last up to 40,000 miles or more depending on their quality and the road conditions in which they are driven.

It is important to inspect your tyres for any signs of cracking or damage regularly and replace them if necessary as this can affect the handling of your vehicle. Additionally, storing your tyres properly when not in use – such as keeping them away from direct sunlight and extreme temperatures – can help prolong their lifespan significantly.

How Much Tyre Cracking Is Too Much

Tyre cracking is a natural part of the wear and tear process that your tyres go through over time. Cracks may start to form on the sidewall or tread as a result of regular use, exposure to sunlight and ozone, age, or improper inflation.

While some small cracks are normal and don’t necessarily indicate an issue with the tyre itself, it is important to check for signs of excessive cracking before taking your vehicle in for an MOT test.

If you notice any slits or blisters in the rubber, then this will likely be classed as too much tyre cracking and could lead to an MOT failure. It is therefore important that you inspect your tyres regularly for signs of damage or excessive wear so that you can be sure they meet all safety standards required by law.

Related Questions

1. Can side wall damage be repaired?

When it comes to tire repair, the sidewall of a tire is the most vulnerable area as it is usually made from soft rubber and cannot be patched or plugged.

Therefore, if you have a puncture in your tire that is located in the sidewall area, unfortunately, it cannot be repaired. This means that any damage caused to this part of your tire will require a new one to replace it.

It’s important to note that when looking for signs of wear and tear on your tires, if you notice any cuts or bulges in the sidewall of the tire then these can indicate potential issues and should always be checked by an expert before continuing use.

On the other hand, if you have a puncture within the tread area* (the grooved part) then this may be able to be repaired depending on its size and severity. If so, then typically this involves patching over or plugging up with a special material that creates an airtight seal allowing you to continue using your tires without further issues.

2. What causes side wall damage?

Sidewall damage on tires is a common issue for cyclists. This type of tire damage can be caused by a variety of factors, such as hitting a pothole or driving over a curb.

Even the normal wear and tear that occurs with regular use can cause sidewall damage to occur. Additionally, sharp objects like nails and broken glass can sometimes find their way onto the streets, creating an additional hazard for car tires that may cause sidewall damage if they come into contact with them.

It is important to inspect your tires regularly to ensure they are in good condition, so you can catch any potential problems before it’s too late. If you do notice any signs of sidewall damage, replace the tire right away to avoid further issues down the road.

3. How to stop your tyre from cracking?

Tyre cracking is an annoying and potentially dangerous problem that can occur when tyres are not properly taken care of. To prevent tyre cracking, it is important to use a quality tyre protector on your tyres.

Tyre protectors help protect the rubber from UV rays, grit, dirt, and water which can all cause cracks in the rubber over time. It is best to choose a water-based solution as some harsh chemicals can actually cause more damage than good. Additionally, be sure to inspect your tyres regularly for any signs of wear or tear and replace them when necessary so you can keep them safe and free from cracking.


These damaged cords are often accompanied by a visible break in the inner liner that allows air to enter into the plies, resulting in an outward bulge or bubble.

Cracks may start to form on the sidewall or tread as a result of regular use, exposure to sunlight and ozone, age, or improper inflation.
