It’s always a tough devoir when one’s bike tire becomes ruptured or depressurized, especially when a bike shop or store couldn’t be accessible straight off. Here are some hacks which will indubitably help you maintain a safer bike PSI.
The acronym PSI stands for “Pounds per Square Inch” and it is the common unit of measurement for pressure.
PSI can be implied as the total amount of force that is being utilized on an area of one square inch. The normal tire pressure is about 32 PSI.
A suitable amount of PSI lets your bike roll swiftly, ride smoothly, and also helps you avoid flat tires. Narrow tires need more tire pressure than wide ones. Road tires typically require 80 to 130 PSI; mountain tires, 25 to 35 PSI; and hybrid tires, 40 to 70 PSI.
Every home used bike tire pressure differ from one another because the more you weigh, the more tire pressure should be.
If a 265-pound rider utilizes 200 PSI on a bike, a 300-pound rider is likely to use 220 PSI.
However, the recommended starting points for your bike tires are:
Road bike tires: 90 PSI
Mountain bike tires: 25 PSI
Gravel bike tires: 40 PSI
Bike tires exude air over time from as little as a few PSI daily to an alarming drop weekly. The imperative thing you could do is to improve on and stick to a routine of a regular checkup before using your bike daily. No matter which type of bike you have, be it a road bike, a mountain bike or a gravel bike, your bike tire pressure changes depending on the type of bike you use, the type of tires you use, the topography you ride on, the temperature in your environment, the weight of your bike and also your weight.
The temperature (hot or cold) outside is one of the universally known factors that could influence your bike PSI. That’s why it’s being recommended that one should check his/her tire pressure every day before riding one’s bike because when the temperatures outside go up by 10 degrees Fahrenheit, your tire pressure will increase by at least one PSI. If the temperature drops or becomes colder and you’re riding outside, for a 10-degree temperature drop, you’ll lose one PSI or more when riding. mostly during cold seasons, your bike is more likely to lose tire pressure drastically which might impel you to fill your bike tires frequently than when you were supposed during summertime.
During summertime, you are more likely to fill your bike tires just the right amount of pressure or a little below the recommended amount of pressure needed. you have to be careful when filling bike tires because all the heat and humidity during the summertime can upsurge your bike PSI which puts you at the dangers of over inflation.
Don’t over inflate. When filling bike tires, more tire pressure isn’t always better, it’s speculated that filling bike tires pressure below the maximum pressure listed on the sidewall would help minimize frequent tire flattening. It’s also right to denote that tires’ sensitivity to damage is always lower to high tire pressure.
If the tire pressure is incessantly too low, it may lead to bursting of the sidewall and untimely tire wear. The proper PSI of a bike solely depends on the type of riding you love to have and the load the tires are meant to bear, this load includes the rider, the bike, and any baggage on the bike. However, riders should fill their bikes the right amount of pressure they want their ride quality to be.
Note that if you are above the average body weight, try to inflate to either maximum PSI or no less than the maximum PSI to reduce the risk of bad topography area.
This depends on the type of bike you own. The right PSI needed for a road bike tire differs from the PSI needed to run a mountain and gravel bike tires.
There’s is actually no specific PSI for bikes. your bike owner’s manual should be always saved to get a PSI range to follow for a proper amount of tire pressure.
Road bike PSI is managed by a certain agency, which involves the width of your tires and your weight. The width of your tires does play a major role in road bike PSI. The wider or bigger your tires on a road bike, the lower the PSI, I.e. The PSI needed on a road bike will always increase with your weight.
However, for mountain bikes, the PSI is not going to be the same as the road bike PSI. The PSI varies if you have a tubed or tubeless tire installed on your mountain bike.
If you use tubed tires that are between 2.35 and 2.4 inches, the PSI should be 29 PSI. For tubeless tires that are nearly the same size, the PSI should be slightly lower or just 26 PSI. For bigger or wider tires, such as those that are three inches or bigger, the PSI will definitely rise. For tubed tires of that size, it’s 20 PSI, and for tubeless tires, it’s 18 PSI.
A gravel bike is more complicated than the aforementioned bikes. Gravel tires are common to run lower PSI. When riding gravel bikes, the lower pressure or PSI allows one to float facilely over bumps providing the rider with better comfort and better grip. A gravel bike with a total load of about 90 kg, with 35 mm tires, the PSI should be between 43.5-50 PSI on the road.
In conclusion, bike PSI varies and there is no specific PSI for bikes. However, you should apply whichever way possible to the betterment of your bike and always remember to inflate your tires to the recommended PSI range or slightly below the PSI range. Never overinflate and always remember that you will feel more gratified with the right amount of tire pressure.
Look out for your bike, you might likely need a couple more PSI than you think.
The PSI that your bike should be at depends on a number of factors like the type of bike you are riding, your own weight, the purpose your bike serves you, and so on. The thing is, recommended PSI levels for tires vary. There is no one-size-fits-all PSI for bike tires. You will have to determine the best PSI for your bike tires on your own.
Gone are the days when bike riders would just buy 23c bike tires for their bikes and put them on the road. Usually, these riders would pump their tires to 110PSI for every biking journey, and then they would allow a little air to get out in order to give the tire a good grip. Times have changed obviously. 25c tires are increasingly becoming the norm. Apart from the rising popularity of 25c tires, the cycling community is now aware that setting their bike tires to a lower pressure would allow for more comfortable riding, will give the bike tires a better grip, and also a better contact patch. Debates are still ongoing about which bike tire pressures are best for riding and which ideal tire parameters allow for optimum bike performance.
Let’s look at an important factor called Rolling Resistance
The higher the tire inflation pressure, the lower the tire’s rolling resistance. Rolling resistance means the opposition the tire gives to rolling on the ground. High rolling resistance is simply not good for your tires. But a low rolling resistance is very good. So, once again, the higher the pressure the tires are inflated to, the lower the rolling resistance of the tire. Also, the likelihood of a tire getting punctured is very low when the pressure of the tire is high as well. So, this means that a high-pressure tire is a good parameter for your bike tires to have. Another thing to note is that the more your bike tires are on low pressure on a continuous basis, the more the tire of the bike will wear prematurely. So, a continuously low-pressure tire can result in sidewall crack of the tires, and a high tire abrasion. All these go to show that high tire pressure is more favorable to your tire than low tire pressure.
What do all these mean for your tire pressure and PSI then?
In order to determine the correct inflation pressure for your tires, you need to consider factors like, the amount of weight /load that will be exerted on the bike tires and the sort of riding you are going to do. The bike weight/load is the combination of the weight of the bike rider, the bike itself, and any other luggage you put on the bike.
Also, different people have different tastes and preferences as to how the rolling resistance of their bikes should be. So, depending on the type of ride quality you want, you should set your bike pressure/PSI to suit it.
Another important fact to note is that narrow bike tires need a higher inflation pressure than wide bike tires. Also, the more load that you give/put on the bike, the higher the inflation pressure in PSI that you will have to pump it with. So, for every added Kg of weight that you have to put on your bike, the more you should add 1% to the PSI.
Which PSI is suitable for my bike?
So, to know the PSI to pump your bike tires with, look at the tire sidewall. There will be minimum and maximum inflation pressure recommendations written there. You can start working with that first. So, if your tires have small diameters/are narrow, you will need a higher inflation pressure/PSI but it must not exceed the maximum PSI stated on the tire sidewall.
The advantage of low-pressure inflation also exists though. Low tire pressure has its benefits/advantages too. For example, if your bike tires are inflated to a low PSI, the tires will have more grip levels on the ground. This is because when you reduce a tire’s PSI, the tire will have more contact patch. When the contact patch increases for a tire, it will increase in grip level. So, if for example, you want to ride your bike on a rainy day or the floor is wet, a PSI of about 7 is recommended. This is because an increased grip level is for your bike tires on a wet day. And only a low PSI can give you that grip level you need.
Another advantage of low PSI is that it is more comfortable to ride on. This does not mean that you should drop your inflation pressure levels too low. It should not be less than the minimum PSI written on the bike tire’s sidewall. So, check to make sure you are within the range. Also, a very low PSI can cause a phenomenon know as, “snake bite”. This happens when the tire pressure is too low hence, the inner tube of the tire gets trapped in between the rim and the tire itself.
But a huge disadvantage to low inflation pressures is the high rolling resistance that your bike tire develops.
So, in summary, if you are looking for speed with your bike, a higher PSI is recommended. If you are looking for comfort while riding, a lower PSI is recommended. For example, with good road conditions, a 25c bike tire can be inflated up to 8.5PSI for speed.
This is just a guess. The ultimate PSI to use for your bike tires depends on your weight, your type of bike, what purpose you intend to use the bike for, the road conditions while riding, the rolling resistance you want, the amount of comfort you want while riding and more. We can’t just recommend a fixed PSI for you because there are so many factors that come into play when deciding. So, use the guide and explanation we have given above to figure out which PSI is best for your bike tires.
