We did buy 4 new tires in Greensboro to replace the factory installed tires(Load D - 65PSI). We put Maxiss - Load E - 80PSI ( around $600 installed ) on our CT32GR.
I noticed an immediate difference in the towing department .... it pulled much easier. On the remainder of the trip(about 1250 miles), we averaged 1.4 MPG better mileage ( increased from 8.0 to 9.4MPG ). :-) That's the good news. The bad news is my trash hauling trailer at home has pretty new tires (3500 miles) for it's semi-annual trips to the dump. :-(
