Why Does a Bicycle Tyre Get Hot When Inflated?

As a cyclist, you know that your bicycle tyre gets hot when you ride for a long time. What you may not know is why.

If you’re like most cyclists, you’ve probably inflated your tyre enough to get it to the right pressure. Then you ride a while, and suddenly, you find that your tyre is too hot to touch.

It’s important to understand why this happens, because it can help you avoid the problem in the future.

1. What Is a Bicycle Tyre?

A bicycle tyre is a rubber-based product that is used to protect the rim of the wheel of a bicycle from the effects of friction.

2. How Does a Bicycle Tyre Work?

The tread of a bicycle tyre is made up of small round tubes called “crotchless tubes.”

When you ride on the tyres, the air is forced out through these tubes and the pressure is applied to the tube.

The pressure is maintained by the presence of a small valve in the tube.

3. How Does a Bicycle Tyre Heat Up?

When a bicycle tyre heats up, the rubber in the tyre softens and expands. This causes the tread to expand, which in turn reduces the contact area between the tyre and the road.

This makes the tyre less efficient at absorbing and dissipating energy, and it can cause the tyre to heat up more quickly.

4. Why Do Bicycle Tyres Get Hot When Inflated?

Bicycle tyres are made up of rubber and a polymer material that is similar to plastic. As the tyre gets hot, the polymer expands and the rubber contracts. This causes the tyre to bulge outward and the air to leak out.

When the tyre is hot, the air inside the tyre expands. The tyre loses air and becomes heavier, which causes the tyre to become harder to roll.

The air inside the tyre also expands and pushes the tyre outward. If the tyre is not properly inflated, the air may escape through the tread.

If the tyre is too hard, the air pressure inside the tyre can force the tyre to deform. This makes the tyre more difficult to roll and causes the tyre to heat up.

5. What Causes the Tyre to Heat Up

The tire is the most important part of your vehicle. It’s the one thing that protects you from the elements and keeps you from getting stuck in the mud or sand.

If the tire is overheating, it could lead to a blowout, which can be very dangerous. So, how does a tire get hot?

The tire is made up of two layers. The inside layer is made up of rubber, and the outside layer is made up of steel. The rubber and steel are held together by a fabric called the “bead.”

The bead is what holds the tire onto the wheel. When the temperature of the tire gets too high, the rubber and steel can begin to melt. This causes the bead to lose its grip on the wheel and the tire to fall off.

The most common cause of a tire overheating is driving in the rain. Raindrops cause friction between the tire and the road. Friction causes the tire to heat up.

Other factors that can cause a tire to overheat include driving at high speeds and driving in the summer.

A blowout of a tire is a very serious problem. It could lead to a serious accident. So, make sure that you keep a spare tire in your trunk and never drive without it.

6. How to Prevent Bicycle Tyres from Getting Hot

There are many things you can do to prevent your bicycle tyres from getting hot.

One thing you can do is make sure you always check that your tyre valves are in good condition.


There are two types of rubber in a bicycle tyre: natural rubber and synthetic rubber. Natural rubber is made from the sap of the Hevea tree.

It has a high elasticity, but is also vulnerable to heat and air pressure. Synthetic rubber is manufactured from petrochemicals.

It’s less expensive than natural rubber, but it’s also more durable and doesn’t get hot when inflated.
