Best Fat Bike Tires of 2021

Want to ride your bike in the most extreme conditions possible? Only a fat bike will get you there.

Changing your tires is an easy way to alter the way your bike feels when you ride it.

For a long time, virtually all-mountain bike tires all came in similar widths. As cyclists ventured further away from paved roads and towards more unruly surfaces, the innovation of fat bikes was born. With bigger tires, you have much better traction and the ability to “float” on soft surfaces like sand and snow. They also provide you with a considerable amount of suspension. Fat bike tires are made for different types of riding, some are optimized for winter use while others are completely slick and feel great on pavement.

Price

In general, fat bike tires are more expensive than traditional width tires. This is because they are still relatively new and considered to be a niche product. Still, compared to other upgrades changing your tires is an affordable and easy way to change the way your bike feels.

Tubeless vs Tubes

Fat bike tires can be run both tubeless and with tubes. There are a few benefits to both.

Tubeless:

  • Can be run at lower tire pressures, which reduces the chances of getting a flat and gives you better traction.
  • Lighter than tubes, especially in extra wide sizes which require huge tubes.
  • Tubeless tires will automatically repair themselves when there is a small puncture. Larger holes can be patched quickly and without taking the tire off the rim.

Tubes:

  • Easier to service and make it much simpler to swap out to different tires, with no messy clean-up.
  • In general, it is cheaper to use tubes than to set your tires up tubeless.
  • In extremely cold temperatures, tubes perform better than tubeless because there is no liquid that can freeze.

Most common fat bike tire sizes

The first generation of fat bikes all used 26″ wheelbases. Therefore, the most common diameter is 26″, although a few new fat bike frames are beginning to incorporate the 27.5″ fat wheelbases. Some fat e-bikes also use smaller (20″) wheelbases. When it comes to 29″ rims, the maximum tire width commercially available is about 3 inches which are considered to be a “plus” sized tire.

Have you been using the recommended pressure?

Because of their gigantic volume, fat bike tires don’t need the same high pressure as regular bike tires. The air pressure of a fat bike tire will greatly affect its performance, and different pressures are appropriate for different types of riding.

A good fat bike tire pressure for summer trail riding will usually fall between 11-16 PSI. This range gives a decent amount of suspension and traction while still protecting the rim from dents.

The best fat bike tire pressure for winter will be lower, somewhere in the 7-10 PSI range. The low pressure gives better traction on iced-over roads and trails.

When riding on the pavement it’s typical to run fat tires at a higher pressure in order to decrease rolling resistance. Remember however that lower tire pressures usually result in fewer punctures from objects like broken glass and metal shards.

Best Fat Bike Tire brands

Most major tire companies offer a few fat tires, however, there are a few brands that really stand out. 45NRTH is a fat-specific tire manufacturer that specializes in winter tires. They offer a variety of studded tires for extreme conditions.

Terrene is another fat-specific company with a wide variety of widths and diameters to choose from. Surly makes a good selection of fat bike tires to match their fat frames, and they were the first brand to offer fat tires.

Several other tire brands have added more fat options steadily over the last few years. Teravail, Maxxis, and Vee offer high quality fat/plus tires.

What is the TPI?

Threads Per Inch – 120 is the average among fat-tire bikes. The more threads, the more durable a bike tire is. A higher thread count also means a heavier tire.
