Fat Bike Tire Pressure

With all the fatbike hitting the road, I thought I'd share some information about tire pressure. I've been planning on this 'test' for a while and last nights dusting of snow was the last element I needed. 

I ran my Pugsley three times down the fresh snow, plus once with the Marin Nail Trail and once with my Kona Dew Drop - this was just for a little comparison with tires and pressures most people are familiar with. 

Here is the total results:

Here's the details of my 'experiment':

Run 1 at 15psi - Nates on Pugsley: 

Run 2 at 8psi - Nates on Pugsley:

Run 3 at 4psi - Nates on Pugsley:

Run 4 at 35 psi - Bontrager on Marin:

Run 5 at 50 psi - Clement on Kona:

Bikes:
Runs 1, 2 & 3 were with a Surly Pugsley with Nate 3.8 inch tires
Run 4 was a Marin Nail Trail on Bontrager Connection Trail 26 x2.0
Run 5 was a Kona Dew Drop on Clement X’PLOR USH 700x35

Rider is 170 lbs and the air temp was 32F.
