Is the air pressure same in bicycle tires and car why would it be different?

The air pressure in bicycle tires is typically much higher than in car tires. This is because bicycle tires are much narrower than car tires, and so they need to be inflated to a higher pressure in order to support the weight of the rider and the bike. The recommended air pressure for a bicycle tire is typically between 80 and 130 psi, while the recommended air pressure for a car tire is typically between 32 and 35 psi.

There are a few reasons why the air pressure in bicycle tires is typically higher than in car tires. First, bicycle tires are much narrower than car tires, and so they have less surface area in contact with the ground. This means that they need to be inflated to a higher pressure in order to provide the same amount of support. Second, bicycle tires are typically made of a thinner material than car tires, and so they are more susceptible to punctures. Inflating them to a higher pressure helps to reduce the risk of punctures. Finally, bicycle tires are often used at higher speeds than car tires, and so they need to be inflated to a higher pressure in order to provide the necessary stability.

In contrast, car tires are much wider than bicycle tires, and so they have more surface area in contact with the ground. This means that they can be inflated to a lower pressure without sacrificing support. Additionally, car tires are typically made of a thicker material than bicycle tires, and so they are less susceptible to punctures. Finally, car tires are typically used at lower speeds than bicycle tires, and so they do not need to be inflated to as high a pressure in order to provide the necessary stability.

It is important to note that the recommended air pressure for a tire is typically printed on the sidewall of the tire. It is important to follow the manufacturer's recommendations for air pressure, as inflating a tire to too high or too low a pressure can be dangerous.
