Swiss asked, "Should the wheels be kept off the ground to prevent flat spots ? or does it not matter."
Several of my cars had been inactive for awhile, and upon cranking up the MRRC 275P, I was surprised to see that not only did the rear tires have flat spots, but that they had melted! There were actual drops of oil on the case under the tires and the rubber had become very hard and brittle, as if the oil had leached out and separated from the rubber. I'm sure everyone has come across rock-hard tires on vintage cars but this was the first time I had seen tires of recent vintage deteriorate (evaporate?) before my eyes. The fronts were fine, and so far I have not noticed any of my other cars suffering from this affliction. Is this common to other brands too, or was it due to a particular formulation used by MRRC?
