Why bicycle tube have more punctures in summer?

Increased Road Debris: During the summer months, roads tend to be busier with increased traffic, including construction vehicles and heavy trucks. This can lead to more debris on the roads, such as broken glass, nails, and sharp objects that can puncture bicycle tires.

Hot Pavement: Hot pavement can cause the air inside bicycle tires to expand, increasing the pressure on the tubes. This can make the tubes more susceptible to punctures, especially if they are already weakened or have small imperfections.

Tire Wear: The increased use of bicycles during the summer can lead to faster tire wear. As tires wear down, they become thinner, making them more vulnerable to punctures from sharp objects.

Dehydration: Dehydration can cause changes in the composition of bicycle tires, making them more brittle and prone to punctures. This can be especially true for older tires that have not been properly maintained.

Underinflation: Underinflated tires are more susceptible to punctures because they have less cushioning between the road and the tube. When a tire is underinflated, it can also cause the tube to bend or fold, which can lead to weak spots and punctures.

To reduce the risk of punctures during the summer, cyclists should inspect their tires regularly for signs of wear or damage, ensure that their tires are properly inflated, and avoid riding over hazardous objects on the road. It's also essential to carry a spare tube and a pump while riding to be prepared in case of a puncture.
