because of the pressure. when you add more air to the tyre, or inner tube, the air inside squashes together, which makes the tyre hard. the pressure is measured is PSI, or pounds per square inch. a fully inflated mountain bike tyre should be around 40 psi. hope this helps

What element makes up up a bicycle tire?
A bicycle tire usually consists of rubber, which is dynamically reinforced with materials such as fabric, fiber, or metal to provide strength, flexibility, and durability. These materials, combined with air pressure, enable the tire to support the weight of the bicycle and rider while providing traction and cushioning.
How do the particles inside a car tire cause pressure on the tire?
When a car tire is inflated, the air particles inside the tire collide with the walls of the tire and with each other, creating a force that exerts pressure on the walls of the tire. The pressure builds up as more air is pumped into the tire until it reaches a point where it is equal to the atmospheric pressure pushing back on the tire.
Why is it harder to walk up a hill than on level ground?
Walking up a hill requires your muscles to work against gravity, leading to more effort and energy expenditure compared to walking on level ground. The incline of the hill increases the vertical lifting component of walking, which adds additional resistance and makes it more difficult to move forward.
What are the differences in tire sizing?
Tire sizing can differ based on the diameter (measured in inches), width (measured in millimeters), aspect ratio (percentage of the tire's width that makes up the sidewall height), and load rating. Different vehicles may require different tire sizes to ensure proper fit and performance. It's important to refer to your vehicle's manufacturer specifications for the correct tire size.
What happens to the pressure and molecules inside. A football that is being pumped up apex?
The pressure increases, and the molecules collide with the football's inner surface.
What happens when you pump up a bicycle tire?
Air goes in it the pressure increases and the tire becomes harder. If you keep pumping it'll eventually blow up.
Why does a tire get bigger as you pump it up?
Because, the air pressure hitting the tire, and as it hitting we put some air pressure into it so the tire is fully pumped up.
Why is it harder to ride a bicycle up a hill?
Because you have to overcome gravity on your way up.
Why does a tire feel harder on a hot day?
The air inside the tire heats up, building the pressure. The pressure is exerted on the walls of the tire, making it feel harder.
What element makes up up a bicycle tire?
A bicycle tire usually consists of rubber, which is dynamically reinforced with materials such as fabric, fiber, or metal to provide strength, flexibility, and durability. These materials, combined with air pressure, enable the tire to support the weight of the bicycle and rider while providing traction and cushioning.
Why is it when you put air into a completely flat bicycle tire the entire tire expands?
because air molecules build up inside the tire and push the rubber outwards which causes the tire to expand.
What happen when more air is pumped into the tire when temperature is kept constant?
When more air is pumped into a tire while the temperature is constant, the pressure inside the tire will increase. This is because the gas molecules become more crowded together, resulting in higher pressure. It's important to not exceed the recommended tire pressure to avoid damage to the tire.
Why does air come out of a bicycle tire when you open the valve even if the valve is pointing up?
Air escapes from a bicycle tire when the valve is opened because of the pressure difference between the inside of the tire and the outside atmosphere. When the valve is opened, the compressed air in the tire rushes out to equalize the pressure with the surrounding air. The orientation of the valve (pointing up or down) does not affect this process.
What keeps car or bicycle tires in the right shape when they are pumped up to high pressure?
the rubber is made to with stand the pressure to a certain point. hope dat helps
Did you blow up bike wheels on a penny farthing?
Usually not. The penny Farthing was invented before the inflatable bicycle tire was developed.
Why do the air molecules inside a bicycle tire speed up as the temperature gets warmer?
As the temperature increases, the air molecules inside the bicycle tire gain more energy, leading to an increase in their speed. This increased speed causes the molecules to exert greater pressure on the walls of the tire, resulting in an increase in the tire pressure.
How do you know the size of bicycle wheels?
Most of the time, the tire will have the size on it. If not, you can look the size up online or have your local bike shop check the wheel size.
