How much did your MPG drop after the CSC conversion?

Well, I'll throw my hat in the ring. With my 2009 I would average 40-41 at back road speeds of 45-55 mph. Converted to CSC Cobra XL in Jan 21, I average 35-35 1/2 at those same speeds. I run a Cobra Trike tire up front at 41psi and the CSC stock Ohtsu tires at 20 psi. Ride is good and I'm satisfied with mileage. Ohtsu tires are wearing like iron. Cobra trike tire is about ready for replacement. Didn't write down replacement mileage but I'm guessing I'll get about 15k or so out of it... Have it's replacement sitting in the garage waiting for summer...

This whole thread is based on the fact the we were led to believe we would lose 3-5 mpg with the conversion. Since the loss is more like 10 mpg, we’ve been trying to figure out if we were doing something wrong. Tire pressure was the first question we came up with.
