Tire pressure?

[Bbqjoe]

I was looking at my tires recently, and on them the suggested PSI is 4-10 lbs. That's a pretty big spread wouldn't you say?

I think I may actually see what they're at today.
I suppose the less pressure the better grip, up to a point.

What do I know?

It's not just grip....it's suspension , lower air pressure softens the bumps.

What if I fill them with helium, or grape jello?

Use Cherry Jello. It is better for off road!

Jello is a waste of... jello. Helium sounds like a good idea, just like nitrogen.

What about hydrogen? (please disregard the fire)
