Rone is correct, the T/A's have a max pressure of 80lbs vrs 44 lbs for the Ragged Trails. The T/A's also weigh 13 lbs more than the RT's.
It takes a lot more air pressure to firm up the sidewalls on the T/A's. If you run at what the door sticker says, you will find that your cornering ability will suffer a lot, plus you will see the outside of your tires wear prematurely.
You just have to experiment a little to find the best pressure for the roads you drive.
Another good thing about the T/A's is that you can air down to 20lbs or so on soft sand, dirt etc., without worrying about spinning the tire off the rims or tearing your sidewalls up.
