I'm gonna jump in a year later...
'12 Rubi 2dr with BFG KM tires on stock 17x9 wheels. What is the lowest tire pressure I can get away with and not have to worry so much about the rubber flopping of the rim?
I'd be driving on sand dunes, and mild rock trails in the summer and unplowed roads and snow covered trails in the winter.
