Bebe said not to go under 15 psi(rocks)seams low for sands about 12 ,I do fine at 18LBS
The beach at cedar point east hampton last weekend I didnt even air down it had no deep spots a(little slippy here and there)
S#1 do you see why I snaped at you for telling me to run 5psi. 
Cant we all just get along  I dont like to argue

Funny, you don't like to argue.
I never said what pressure to run in your H3. I told you how to determine what pressure to run in your H3.
Your the one that got stuck on 2 PSI and 5 PSI. If you read my original post you will see I used the fallowing phrases:
"It
depends on the tire and weight of the vehicle"
"
in most cases your looking at about 5 PSI"
"
may be anywhere from 2
to 10 PSI"
These are called generalities. Most Americans have learned this by they time they get to a fifth grade English class. I apologize if I have over estimated your grasp of the English language.
I've only had my H3 a few weeks. I haven't taken it off road, so I don't know specifically what the tire pressure ends up being.
I do know that 25% is 25%, but remember, this is to get
"a good ballpark" . If you are having a hard time with the concept of reducing the sidewall height by 25%, go out and measure how high off the ground the bottom of your rim sits. Respond with that measurement here and I'll do the math for you and let you know what height you need to go down to. At that time it will be your responsibility to use a tire gage and find out how much PSI is in your tires. You may want to go a little lower on sand or keep it a little higher on sharp rocks The the key words were
"a good ballpark" . If you don't understand the way in which I have used the term "ballpark" go
here and look at definition number 2.
Last time I was on a beach (North Padre Island) I was running 4 PSI in my F150 my buddy was running about the same in his full size Dodge. We ended up with a guy in a Ranger tagging along with us. This run is 110 miles of mostly soft sand with a mile or two of shell and an additional 10 miles of packed sand and 10-15 miles of highway to the closest gas station. We hit one of the area of shell at high tide. The guy in the Ranger was worried about trying to pass because he almost got stuck a few times and was running low on fuel as it was. After talking with him a bit we found that he was running 20 psi in his tires and had been in 4wd the whole time (normally you use 4wd when you start and stop and kick it in to 2wd the rest of the time). We dropped his tire pressure down and he was able to make the rest of the trip without getting stuck (the way home was all lose sand) or running out of fuel, and had a lot more fun in 2wd.
Maybe the beach you were on and didn't air down was hard packed an you didn't need to, or maybe you just didn't know better like the guy that was with me in the Ranger. The difference is that the guy in the Ranger could see how little air we had in our tires and could see that it was working for us and believed us when we told him that it would work for him. He learned a little something on that trip.
fourfourto, I'm not arguing with you, I'm just trying to explain it to you. Your the one calling me stupid and throwing out the
