a man tries to make a tyre lighter by filling air in it. is it possible?
Inflating Tyres: Is it Possible to Make Them Lighter?
- Thread starter Himal kharel

In summary, filling a tire with air does not make it lighter, as the air becomes compressed and actually adds weight to the tire. Even filling it with hot air does not make a significant difference in weight. Therefore, it is not possible to make a tire lighter by filling it with air.

Hi Himal! 
What do you think?
If you had a boat full of tyres, and you wanted to make the boat lighter (so it didn't sink), would air help?

when it is inflated, the volume increases but the air becomes compressed.
the net force will be
actual wt of tube+weight of air-upthrust
m(of tube)*g+V(of inflated tube)*d(compressed air)*g-V(of inflated tube)*d(normal air)*g
A density of compressed air >density of normal air so instead of being lighter it becomes heavier. So it is impossible

What about filling the tire with really hot air?

With an equal amount of air in a cold tire and a warm tire, the warm tire is SLIGHTLY lighter. But the difference is so small there is no benefit that you could get from it.
1. How can lighter tyres be beneficial?
Lighter tyres can provide a number of benefits, including improved fuel efficiency, faster acceleration, and better handling. They can also reduce wear and tear on other vehicle components, such as the suspension and brakes.
2. Is it possible to make tyres lighter without sacrificing durability?
Yes, it is possible to make tyres lighter without sacrificing durability. This can be achieved through the use of advanced materials, such as carbon fiber, that are both lightweight and strong. Manufacturers also use innovative designs and construction techniques to create lighter tyres that are still able to withstand the demands of driving.
3. How does the weight of a tyre impact its performance?
The weight of a tyre can significantly impact its performance. Heavier tyres can increase rolling resistance, which means the engine has to work harder to move the vehicle, resulting in reduced fuel efficiency. Lighter tyres, on the other hand, can improve handling and responsiveness, leading to a smoother and more efficient driving experience.
4. Are there any drawbacks to using lighter tyres?
While lighter tyres offer many benefits, there are also some potential drawbacks to consider. Lighter tyres may not be as durable as heavier ones, and they may not perform as well in certain weather conditions, such as snow or ice. Additionally, lighter tyres may be more expensive due to the use of advanced materials and technologies.
5. Can tyre inflation impact the weight of a tyre?
Yes, tyre inflation can impact the weight of a tyre. Overinflating a tyre can make it appear lighter, but this can actually decrease its performance and durability. Underinflating a tyre can also affect its weight, as it may cause the tyre to wear unevenly and potentially lead to a blowout. It is important to follow the manufacturer's recommended tyre pressure for optimal performance and safety.
