Anyone tried 33x9.50-15's?

Merry Christmas! I was wondering if anyone here has been offroad with unusually skinny offroad tires like the 33x9.50 and the 33x10.5. I'd like to here about their ride quality because I've heard rumors they don't respond well to low tire pressures (ie. under 20 psi) as common tires like the 31x10.5, 32x11.5 and 33x12.5 do. Do they run rougher? Is it true that they don't like soft tire pressures? I was thinking I'd prefer to run a 31x10.5 or 32x11.5 if the 33x10.5's or 33x9.5's aren't as flexible. (I've heard that running tires like 33x12.5's or bigger often brake stock axles and I don't have a lot of money for upgrades)

Any advice will be appreciated!
