If you’re a cyclist, you’ve probably wondered if your bike tires should look flat when riding. The answer is no. Riding on deflated tires can slow you down and increase the risk of slipping and falling. It can also damage your bike components such as the rims. In this article, we’ll explore the importance of tire pressure and how to find the right pressure for your ride.
Understanding tire pressure basics is crucial for any cyclist. Tire pressure is measured in pounds per square inch (PSI). The optimal PSI for your bike tires depends on factors such as your weight, the weight of your bike, and the type of riding you’ll be doing. For example, if you’re a heavier rider, you’ll need more pressure in your tires than a lighter rider. Similarly, if you’re riding on rough terrain, you’ll need more pressure than if you’re riding on smooth roads.
To measure and adjust tire pressure, you’ll need a tire pressure gauge. You can find these gauges at most bike shops. To measure the pressure, unscrew the valve cap and press the gauge onto the valve stem. The gauge will give you a reading in PSI. If the reading is too low, use a pump to add air until you reach the recommended PSI. If the reading is too high, let some air out until you reach the recommended PSI.

Maintaining the correct tire pressure is crucial for a comfortable and safe ride. However, many cyclists make mistakes when it comes to tire pressure, which can result in a less enjoyable ride or even accidents. Here are some common tire pressure mistakes to avoid:
Risks of Overinflated and Underinflated Tires
Overinflated tires can make your ride uncomfortable and increase the risk of a puncture. When the tire pressure is too high, the tire becomes less able to absorb shocks from the road, making the ride feel bumpy and harsh. Additionally, overinflated tires have a smaller contact patch with the ground, which can increase the risk of a pinch flat or puncture.
On the other hand, underinflated tires can also be dangerous. When the tire pressure is too low, the tire can become deformed and more susceptible to punctures. Underinflated tires also increase rolling resistance, making it harder to pedal and slowing you down.
Misinterpreting the ‘Feel’ of Correct Pressure
Many cyclists rely on the ‘feel’ of their tires to determine if they are properly inflated. However, this can be misleading. A tire that feels hard may not be properly inflated, and a tire that feels soft may be overinflated. The best way to ensure your tires are properly inflated is to use a tire pressure gauge.
It is recommended to check your tire pressure before every ride and adjust it as necessary. The correct tire pressure varies depending on the type of tire, rider weight, and riding conditions. Refer to the manufacturer’s recommendations or consult a bike mechanic for guidance.
By avoiding common tire pressure mistakes, you can enjoy a smoother, safer, and more comfortable ride.
