Answer
George,

I think you need to very carefully read the sidewalls of the tires.  I'm going to bet they say the maximum pressure is considerably higher than 41 psi.  On RV's that use ST type tires, that is the pressure you should be using.

I'm going to bet the sidewalls are starting to fail.  

You need to get the vehicle to a tire dealer immediately - not tomorrow - NOW!  And drive slowly - no more than 35 moh.
