I hope anyone can help me this. I have a gravity bullseye monster fatbike with 26 x 4 inches tires. I've tried to pedal it on loose sand as in the pictures but I couldn't. I've lowered the gears to get the maximum toque and lowered the pressure till 3 psi but in vain. I have asked a lot of manufacturers online but I did not get any helpful answers. Are there are any tires suitable for this type of sand? Can I add a chain or something around the tires? will they help? Below are pictures of the sand & my bicycle.
