Cobra Tire Problem

Hey all,
Got a tire problem and some related questions.
I installed a set of 4 BFG G Force KDWS 245 45 17s on my 96 Cobra about 5,000 miles ago. They were extremely quiet until I rotated them last night, using the standard back to front same side, fronts to back cris-cross rotation. Now the tires are very loud. Alignment was done right after the tires were installed, and the wear looked fine (almost nonexistent) when I rotated them.

Questions:
1. Is the noise because the direction that the rear tires are turning is now opposite what it has been since they were originally installed on the car?

2. Will this noise likely go away once the tires have settled/"worn" into their new wear patterns where currently installed? I've driven the car less than 60 miles since rotating the tires.

3. Should I have just done a front to back same-side rotation? These are non-directional tires.

Any help will be greatly appreciated!
Thanks

Hmmm, I thought those tires might be directional (look at the tread pattern?). I would vote for #3. "Undo" the criss-crossing & just keep things on the "same-side" to see if things improve.

They are definitely non-directional. But I do tend to agree with your suggestion.

I have the same tires. Do the same side font to back. What does it sound like? I have a slight sound by the driver's side rear. It is a slight "whump whump whump' sound. Trying to figure out if it's the tire or rim or maybe a bearing noise.

They don't whump; they have a sound sort of like a truck tire with aggressive tread. Until I rotated them yesterday, they were as quiet as the Michelins on our Sebring Convertible.
