Having the right bike tire pressure is critical to your bike performance. For road bikes, you want the perfect mix between comfort and low rolling resistance. For mountain bikes, you want the best grip without rolling the tire of the rim or getting pinch flats.
If you have ever compared two bike pumps you will probably have noticed that they don’t read the same pressure. The standard pressure gauges on pumps tend to be quite inaccurate.
So bringing a small sensor on your rides is a great way to be sure you have the right pressure and can focus fully on crushing your KOM or sending that gnarly section.
Top 6 Best Bike Tire Pressure Gauges
1. Topeak D2 SmartGauge Bicycle Tire Pressure Gauge
- Dimensions: 4.1 x 1.8 x 1.4 inches
- Maximum Pressure: 250 PSI
- Weight: 2.24 ounces
- Power Source: CR2032 battery
- rotating head allows for easy read from different angles

Tire Pressure 101
Proper tire pressure for bikes is essential for a good ride and to prevent damage to your tires. You will roll more quickly, smoothly, and be less likely to pop a tire and need to replace it. Proper tire pressure for road bicycles requires anywhere from thirty to one hundred thirty PSI (pounds per square inch) or pressure.
What is the best tire pressure for a mountain bike?
Mountain bikers probably spend more time thinking and talking about their tire pressure than any other bikers.
And for good reason.
Too much pressure gives you very little grip. The wheels bounce on every small bump and have very little contact with the ground. They also don’t deform as much on rocks and roots leaving you with a tiny contact area and sliding around on everything.
Too little pressure and you have pinch flats all the time. Rock edges can dent or even crack your rims. Especially carbon rims can easily get destroyed this way.
You can also run into issues when cornering. The tire can burb out all it’s air if it’s tubeless. It can also completely roll off the rim. So it’s not good to have too low pressure in your tires.
And it also depends whether you are using tubes or tubeless.
There is no one-size-fits-all psi number that is good for everyone. You will have to find out for yourself.
25 Psi is what I would recommend as a starting point. I like to use the following guidelines:
- Tubeless tires can run with lower pressure than tubes
- Front tires are generally softer than the rear
- If you are running inserts, you can use a lower pressure
- Higher pressure will give you low rolling resistance on smooth jump trails
- Lower pressure will give you more grip on rough terrain
How to Pump Up your Bike Tires
Pick the Right Pump
There are two different kinds of bicycle pumps to choose from the Schrader valve and the Presta valve. The Schrader valve pump is wider and flatter than the Presta valve, which is narrower and comes with a locking nut to prevent air escaping. Make sure you have the right kind of gauge to measure your tire pressure and the right kind of pump for your bicycle before you begin.
Before you begin pumping, you need to know the PSI rating for your tires and your weight. Together, you can adjust the amount of pressure you add to your tires, so you will get the smooth ride based on where you ride and the kind of tires you have. As you prepare to pump more air into your tire, ensure the pump head fits tightly over the valve, so you will not leak air, and the air goes into your tire.
Follow the PSI
If your pump has a PSI gauge, let the PSI readings be your guide for how much air you are adding. You can use a hand or foot pump to push air into the tire to the middle range of your tire’s ideal pressure. If it is your first time, take the bike out for a short ride and adjust the pressure from there. You can more accurately gauge the amount of air your bicycle requires by trial and error in the beginning until you know exactly the right PSI for your bicycle and body weight.
How To Check Your Bicycle Tire Pressure Without a Gauge?
If you don’t want to carry a small gauge, or don’t have one yet, you can use the following methods to get an indication of the pressure.
Road feel: Generally you will feel it if your tires are softer or harder. This is not very accurate but you don’t even have to get off the bike.
Pinch the sides: This method is maybe the most widely used. Personally, I find it hard to get an idea of the actual hardness of the tire. On most tires, the running surface is much thicker than the sides. So the feeling of the sides is not directly comparable to the feeling on the bike. However, many people use this so it might work for you too.
Use thumbs to push on the running surface: This is the method I always used before I got a bike tire pressure gauge. It gives a good idea of how much the tire will deform on the road or dirt. This also works better than using the sided since the sidewalls can be much thinner than the top.
It’s not perfect though
You are still measuring with your hands. And our hands can be stronger or weaker depending on the situation. So what feels like a good pressure when you just wake up might be different from when you have just been working out.
