I love them! Only reason I'm selling is I'm upgrading to 35".
Getting 315/70 installed tomorrow. As for size I believe they are true. They basically work out to almost the exact over all diameter just a little wider than stock SRA.
On road they are great in all seasons, they rumble a bit but t is not too much. Just enough to remind you that you have lock ass tires.
Off road never had an issue.
