4 Things You Need to Know About Your Bike’s Tire Pressure
Many cyclists love to get various upgrades for their rides, but they often neglect one of the simplest and more important ways of improving their two-wheeled friend. I am talking about having the right tire pressure, of course. Tire pressure is a complicated thing because it is affected by almost everything (from how often you brake to the width of your rim) but it can be very simple at the same time and, because it is free, you can adjust and play with it until you find the pressure that suits you. Here are a couple of things everyone needs to know about their bike’s tire pressure.
Adjust It to Your Tire Volume
Whatever kind of bike you are riding now, in today’s bike fashion world, everyone is crazy about plus-size tires. If you are switching from traditional 23mm to 25 or 28mm, you will be increasing your tire volume significantly, and you will need to adjust the air pressure. If you have been inflating your regular tire to 100 psi, then a 25mm tire needs to be inflated to 85 psi and a tire of 28mm to 70 psi. These are just some starting points that you can play with, but in the end, it all depends on your weight and riding style.
Air Pressure Fluctuates With Temperature Changes
Everyone knows that tire air pressure won’t stay constant all the time. It will change in accordance to tire’s temperature. That’s physics, right? But, by how much? Rule of thumb, if the temperature changes by about 10 degrees Fahrenheit, it will increase your tire air pressure by 2 percent. For road riders, that is roughly 2 psi for every 10 degrees. It may seem unimportant, but even a small drop, 3 to 5 psi, can make a huge impact on the riders stability and stiffness. Temperature is not the only thing that can affect the tire pressure. Extensive braking can boost the temperature inside the tire for about 300 degrees. A tire which would normally be inflated to 90 psi in 70 degrees will at that point be inflated to 115 psi. Therefore, avoid overusing the brakes.
Maybe the Gauge Does Not Measure It Correctly
A majority of floor pumps have a gauge, but many of those gauges are often off by 10 psi or more. It is important that your tires are always inflated to the right tire pressure, especially if you are riding a mountain bike with wide tires, where even a slight difference in the pressure can put you a lot of danger.
To always be sure that your tires are inflated to the right pressure, consider getting a tire pressure monitoring system, like the FOBO Bike system. The FOBO Bike system is a tire pressure monitoring system that works wirelessly, using Bluetooth 4.0 connection, and it works with your Android and iOS smartphone. This way, you will always know when the tire pressure has changed, because the sensors will send an alert to your smartphone.
It Depends On the Riding Surface
I bet you are already familiar that a tire that is wider rolls faster because there is less sidewall deflection. But that is not all. If the surface you are riding on is tougher, having lower air pressure will help. But, if you are riding on an unpaved road or on bumpy surfaces, which every rider hates for that uncomfortable buzzy feeling, having higher air pressure on your tires will deflect that surface and create better resistance.
These are the four important things you need to know about your bike’s tire pressure. As you can see, it is nothing complicated. You just need to be aware of certain elements that can affect your tire pressure. So, monitor your pressure constantly, use TPMS devices like the FOBO Bike system, and you will make your ride smoother and much safer. With the knowledge you have gained by reading this article, you will not experience any problems keeping air pressure in your beloved bike’s tires just right.
