Fat Bike Tyre Pressures - 14, 12, 10, 8, 6, 4, and 2 psi
bicycles reviews | bicycles videos | bicycles online
Demonstration of different tyre pressures on a fat bike. I searched in vain for a video like this before I got an accurate pressure gauge; hope it might be of use to someone looking to get a rough idea of what pressure they're running. I've found that roughly four chambers-worth of air from a floor pump gives about a one-psi rise in air pressure in these tyres. Also, if you get the tyre pressure sorted indoors and then head out into sub-freezing temperatures, you can expect it to drop by around a third to a fifth, depending on how chilly it is out there and how much pressure is in the tyre to start with. For this video, I made pressure adjustments and readings outside for accuracy's sake.

Discrimination against odd numbers!

Which setting is good for sand and snow?

very nice video i currently thinking on building a fatty poppa bike thanks for showing and giving me an idea on how much give and soft i could expect cause i seen max 15 psi pressure and though the tires would look flack at that psi but to my amazement they look awesome thank you very much for taking your time on posting such a help full video

Thanks for the post, super helpful while waiting for a gauge to arrive. Have you had any sidewall problems with running such low pressures?
-
This is extremely Helpful. Thanks a whole lot.
-
i`d choose 6 to 8 psi for light trails, and 12 for paved roads. how many psi do you normally run?
-
at 14 psi the tube seems likely to pop out on the inner rim. weird.
-
Hugely helpful. Thanks! :)
-
Sounds like a lot of creaking going on with that bike?
-
At what point (PSI) do you feel like you would have issues with pinch flats?
-
Do you have tubes in these tires?
-
How do you actually know the PSI of each setting? Maybe I don't have an accurate gage. My floor pump doesn't register down past 8-10 PSI. After that, it's just the squeeze I use to gage anything lower. Got any ideas on gages that go that lower, or lower? Thanks.

Thanks for the share, it looks like 8 psi in front in 10 in the back is about rite? Is that the surly karate monkey?

Thanks. Interesting to see that aspect BUT if you were to demonstrate traction on a trail for each of these it would correlate the importance of setting the pressure versus conditions. I've found that most all new fat bike riders can't seem to understand how soft the tires need to be for optimum traction in soft snow. Based on the squish, I'm guessing that you weigh 170 lbs (tops).

Good video. The tire pressure on fatbikes is all about feel and what the conditions need.
