What’s everyone running for tire pressure? First year with a fat bike and I’ve heard pressure makes or breaks a ride. Do you change pressure based on conditions?

I got my first Fatty this past winter. I weigh 128. I initially put 10lbs and was bouncing off absolutely everything, too hard. I looked into it and dropped it down to 5-6ish. Works great. I had a rigid and it felt like I was riding a full suspension.

I’m running around 18 lbs . I’m riding mine daily for commuting to work. I weight about 205 and wear a pack with another 10 lbs in it.
A month ago the pressure was running low at 12 or so and it was very sluggish , thought I was suddenly very outta shape
Temperature and tire pressure make a huge difference with fat bikes. Set your pressure to 10psi when it’s inside at 20°c and it may be 5 psi when it’s -5°c out.
I’ve run down to 1 or 2 psi in soft snow conditions. A 0-15psi pressure gauge is handy to have if you want to get the most of your fat bike.

I use a digital pressure gauge and a low pressure, high volume Blackburn pump to set up my fatty tires. I usually run 7-7.5psi front and 8-8.5psi rear on 45Nrth Wrathchild 4.6s. I could probably go a little lower, especially with the Bluto on the front.
I weigh about 160lbs.

Are we talking tubeless or tubes here? If memory serves me I think I was in the 6-8 lb range last winter. More in rockier, less snowy conditions, Less in the deeper snow. I always felt I could go lower but the thought of flatting a fattie back in the boonies didn’t appeal.

Tubeless.
Thanks - this is probably the first time I’m actually not disappointed to see snow in the forecast!

I ran tubeless last year and was at 5psi rear / 4psi front. I was dropping it down lower if I had any bouncing or traction issues.

Fatbike, Marty?

Sheesh, I run tubeless as well, but at pressures below 6 psi, I was smacking the rear rim on rocks and bottoming it out on drops. I know you’re not supposed to hit drops on a fat bike, but it’s too fun not to.

I figure I’ll start at 6 and dial down a bit if conditions warrant. Tomorrow morning looks like it’ll be gold.
I figure I’d rather do snowed in ATV trails and logging roads, than be out on the road when it’s -10.

Lol I’m not even considering drops on my fatty. It’s a rigid and I’m over 200lbs. Do curbs count
?
I hear ya, figure I’ll make a drive to Truro once in a while to take advantage of their fatty trails on my xc bike.

I plan on snowshoeing Knuckle Buster tomorrow morning, if we get enough snow.

Definitely slick out there. I need to drop the air pressure some more for traction
We rode about 13k in Spider last night late, should be killer now for fatties til milder temps next week.
Everything good to go:
Replicator, Inner Peace, Ribbon, Flow, Western Front, Clearcut Crossover, north half of Poker, Sunrise Strip (1.5k of new singletrack)
Closed: Skull Trail
Happy Trails!
