Fat Bike Tire Pressure [Complete Guide]

Fat bike tires are often more than twice as thick as standard mountain bike tires. This makes them heavier and more difficult to inflate. It is important to know the proper pressure for your tire in order to prevent flat spots and slow punctures.

The pressures for fat bike tires are usually between 2 – 25 psi. The pressure will depend on the weight of the rider and the terrain that they are riding on.

In this article, we will discuss fat bike tire pressure and the most important factors you should consider when choosing tire pressure for fat bikes.

Fat Bike Tire Pressure Chart

Fat bike tire pressure charts are a convenient way to find the correct pressure for your tires. They come in handy when you don’t have a pump or if you have to check on different tires.

The following is a list of tire pressures for fat bike tires under various conditions:


Fat Bike tire pressure on the pavement is the pressure the tire needs to be inflated when riding on pavement, as it is different from the pressure of a normal bicycle tire. The pressure of a fat bike tire on the pavement is typical.

Pavement: 10-12+ psi

Fresh snow

Fat bike tires are designed to be ridden on snow and other slick surfaces. Depending on the tire pressure, this can cause the tire to slide easily on fresh snow.

In order to prevent a fat bike from sliding, it is important to know the correct pressure for your tire.

Fresh snow: 1-4 psi.

Packed snow trail

Many people who ride fat bikes in the winter often don’t know how to adjust their tire pressure when riding on packed snow trails. This can lead to a dangerous situation where the tire becomes too soft and loses traction.

If you’re riding on packed snow, you should be able to get away with a lower tire pressure than if you were riding on dry ground.

Packed snow trail: 2-8 psi

Softer packed snow

When riding on softer packed snow, it is important to reduce the pressure of the tires. This will allow more traction and give more control.

This is because when riding on softer packed snow, you will encounter a lot of bumps and dips, which can cause your tire to lose pressure.

Softer packed snow: 4-5psi

Groomed snow trail

Fat bike tires are not designed to be ridden on groomed snow trails. The pressure in the tire is too low and it’s harder for the tire to grip.

The recommended tire pressure for groomed snow trails is around 1psi. If you have a fat bike with a standard road tire, then you should be looking at around 4psi.

Groomed snow trail: 1-4 psi

Wet packed beach sand by the surf

When riding on wet sand, fat bike riders need to know how much air pressure is in their tires. If they don’t have enough pressure, they will sink into the wet sand and become stuck.

They also need to make sure that their tires aren’t too tight or too loose so that they can ride comfortably over the terrain.

Wet packed beach sand by the surf: 6-8 psi

Loose sand

When riding on loose sand, you’ll want to keep your tire pressure a little lower than usual. This allows the tire to grip the sand and not sink in too much and lose traction. However, when riding on loose sand, the tire pressure should be lowered to about 6 psi.

Loose sand: 4-6 psi

Rocky trails

Fat bike tire pressure on rocky trails can be tricky to figure out. There are many factors that affect tire pressure, including the type of tire, the terrain, and how much weight is on the tire.

When riding on rocky trails, you should keep your tire pressure at 10psi or less. This will help the tire to stay in contact with the ground and help it roll over rocks with ease.

Rocky trails: 6-10 psi

How To Determine Tire Pressure for Fat Bikes?

Fat bikes are usually ridden on soft surfaces, like sand and snow. They don’t need to be ridden on roads because they are designed to take advantage of their large footprint.

The lower tire pressure can also affect traction and steering in sand and snow, so it’s important to know how much air you’re putting in your tires before you ride them on these surfaces.

There are two ways to determine your tire pressure: using a digital gauge or using an old-school hand-held pump.

What PSI Should A Fat Bike Tire Be?

A Fat Bike tire should have a PSI no higher than 12 PSI. Typical fat bike tires are around 2 – 12 PSI, but it depends on your wheel size and what you want to accomplish with your ride.

PSI is an important number when it comes to fat bike tires. It can tell you the pressure you need to have traction on any surface.

If you’re riding on soft snow or sand, then your PSI should be lower than if you’re riding on rocks or hard snow.

Why Is Fat Bike Tire Pressure So Low?

Fat bike tires are low pressure in order to get a better grip on the snow or ice. The low pressure allows the tire to work as a wedge and create more friction with the ground. It also allows for traction on snow and ice because of the low rolling resistance.

How to Put Air in Fat Bike Tires?

In order to put air in a fat bike tire, you will need an air compressor at the ready. This should be attached to the valve stem using an adaptor that has been threaded onto it.

  • Step 1: Remove the valve cap from your fat bike tire.
  • Step 2: Fill your tire with air using an air compressor or hand-held tire inflator.
  • Step 3: Replace the valve cap back on your tire.

Best Fat Bike Tire Pressure Gauge

A tire pressure gauge is a tool that helps users to keep their tires in optimal condition. It is a must-have for every bike rider and bike owner.

The best fat bike tire pressure gauge is the one that has all of these features: accurate, durable, fast-reading, and easy to use.

3 Best fat bike tire pressure gauge:

  • JACO ElitePro Digital Tire Pressure Gauge -100 PSI
  • AstroAI Digital Tire Pressure Gauge 230 PSI
  • Vondior Tire Pressure Gauge – (0-60 PSI)


How do I know what PSI my bike tires should be?

PSIs are usually found on the sidewall of each tire and are usually written as “120/70-17”, meaning that this tire has a 120-pounds per square inch rating and that it was designed for use with tubes that are 70 millimeters wide.

What PSI should bike tires be?

The PSI rating is determined by the manufacturer of the tire, but it should be between 80-120. The recommended PSI for bike tires varies depending on the type of riding you do. For example, mountain bike tires should have a PSI of around 25 to 35 or more while road bike tires should have a PSI of 130 or less.


The conclusion of this article is that fat bike tire pressure should be adjusted to the tire size and terrain.

When you are looking to buy a new set of fat bike tires, it’s important to know what type of pressure they need. This will allow you to purchase the right tire for your weight and riding style.
