What Tired Pressure to Run A full suspension MTB
I am still trying to figure out the best tire pressure for my MTB. its a Full Suspension Rocky Mountain. Element 50
I am very paranoid about getting flats so i run a high tire pressure about 45 to 50 psi for doing trails. Most of the trail in my area have lots of roots and lots of single track. But i am still finding traction problems for going into mud. Tires are really good though good quality.
What tire pressures do you all recommend best for a MTB that is full suspension

Would look at the side walls and initially go with the lower end of the manufactures recommended pressures; 50psi is a bit high for off road MTB.
You haven't given any info about whether you are running tubes, tubeless (conversion) or tubeless (UST); if you want to run low pressure, with out the risk of pinch flats, tubeless is the way to go, but is cost more. Regardless, you need to know how to fix a flat with the type of setup you are using.
For tires, again, which ones, you can get good quality ones which will excel in the dry, but will be useless in mud, one tire does not fit all conditions

No easy answer. Lots of trade offs. And I agree with cript - flats are easy to fix and you should be prepared to do it. Higher pressure will not prevent flats. I with between 30 and 50 depending on various factors including how I feel. Do I want a softer ride or traction etc...

I run more pressure (40-45lbs) on my Full Suspension because I expect my shocks to absorb impact. I also live where the group is pretty hard. I want lower rolling resistance. BUT when I know I am going to hit changing situations or sand and gravelly stuff I use lower pressure (28 in back 30 up front) to grab better. YMMV
A hint I picked up here that helped me out was to push your front tire into turns. Don't lean into the turn, keep a good posture, but put pressure on your grip on the side you are turning into and push your front knobbies into the ground. Seems to work and helps me corner and do switchbacks better. Check out the STICKIE Thread for Techniques New Riders. Tons of good help there.
And yeah, practice changing flats at home. Fixing an old tube without a bucket of water. Its a good skill to have.

Between OR, IL, and upstate NY, I've never run more than 30psi. 145lb pro xc racer.
Rolling resistance tests have actually shown that grip is lower and rolling resistance is higher at the higher pressure you guys are using.
Tubeless and finding the proper pressure for your tires, weight, and riding conditions is key.

i use regular tubed tires
I run regular Tubed tires. Traditional tubes the old fashion way. Thats why i run a high pressure

While I agree about grip I am not so sure about 'rolling resistance'. Your statement is very counter-intuitive. Do you have a link to these tests?

The basic premise is this:
At high pressures, your tires bounce over every imperfection in the trail surface. Your energy is used for UPWARD movement, instead of FORWARD movement.
At lower pressures, your tires are able to deform over trail imperfections (rocks, roots, gravel), so all of your energy goes towards going FORWARD, instead of propelling you over every little bump.
This is just one link, but there are many. If you were to look at WC MTB tires over the years, they've become wider and wider. Dudes aren't running 1.5" tires anymore.

I dont think I have ever pumped my tires above 35...

As others have said, yeah, that's pretty damn high. Depends on where and what your trails are like, and how you ride them. I run 30psi, give or take a couple depending on how wet/dry things are, and what particular trails. And yes, tubeless is the ****.
