Hi
I regularly ride my fat bike on rocky river beds. I keep the tires at around 9 psi, which is quite firm for the terrain. I weigh 225 lbs and ask if anyone has tried going lower without the risk of snake bite?
I'd like to go lower for more forgiveness, but don't want to be stuck with a flat.

If you have not already investigated, look into setting up your bike tubeless. Most main-line fat bikes are now coming ready to be set to such, with the addition of sealant and valves.

Experiment at home. Lower the pressures and ride up and down the curbs or find some bricks to ride over. Be deliberately rougher in your technique in an attempt to bottom out the tire. Just keep exploring lower and lower pressures. If you go to far, you'll know right away. And if you have any problems, the tools are right there in the garage.



**assuming you have a garage and tools and know how to use them.

It depends on the size of the tires. Larger tires require less pressure to support the same amount of weight as a smaller tire. You should not be running the same pressure in both tires, because the rear supports a larger portion of the weight, so lowering the front makes for a smoother and more even ride. On my 27.5 plus bike with 2.8" tires, I run 12.5psi in the rear and 8.5psi in the front at 165lbs body weight.

Apologies, I was referring to 26 X 4.0.
I am not ready to go tubeless, just yet.
Yes, I can always experiment, I was hoping to hear from some one with experience

Thank you

Tubeless is the way to go. Rim width and what tire? Front suspension? Best? Get a low pressure tire gauge and use it. No tubes, no pinch flat.
