My ride has been rough as hell (but I like it!) since I went with 285/60s. It's kind of a rule of thumb though.... the larger the tire, the more your ride becomes work.
Trimming with 285s is touch and go here on stock height. Some members claimed little to no trimming, but I had to go with a lipo, tuck, and chop. LOTS of trimming. Cranking the torsion might aid in less trim, but I voted not to. My tires also protrude from the well a good 1" which increases trimming for clean turns. I get no rub now, but in reverse while turning, I get a little bite sometimes. Of course, I have to revisit trimming again soon since the body shop just put a new front bumper clip on. They shaved it down some, but not enough.
As for the attitude, that is a surprise. Maybe the email listed for some folks here are not up to date. I get emails occasionally from members so I know mine is correct. Maybe we all need to do a house cleaning on our listed info. *shrug*
