Tire pressure [Reifendruck] - oTo - 2012-04-14
whats normal pressure for downhill bike? I use 43PSI for both, front and rear tire because I do lots of flats. Is that too much?

Different pumps often show very different pressures. So it's not that easy to compare the pressures.
I have not seen a downhill tire with 1.95" yet - except special tires for heavy rain/mud conditions (or for meadow dual slalom or snow races). So it seems you do not have a downhill tire. Switch to real downhill tires with 2 ply casing. Then you can go down to 1 bar without having too much flats (depending on your weight, the rims, ...).
I usually ride with a higher pressure at the rear wheel. E.g. 1.5 front, 2.x rear.

yeah... with 3.0 you don´t have enough grip to ride on a downhill track or in the forest.

if I lower pressure will not i get contact with rim and obstacle? when riding on high speed when you hit bump or on big jump or on flats? :| even when going fast on stairs ?
I have pressure this high because I think it will protect rims

That's right.
But it doesn't make sense when you run that high pressures in your tires, because you will lose to much grip. Usually DH-Tires have pretty stiff side walls and the possibility of flats is even at low tyre pressures (1,5-2,5 Bars e.g.) not high.
