Well, bad news for me last night. Went in to have the tires balanced and rotated, hoping that it was just a minor issue giving me vibrations, but it seems that when I slid into a curb last winter it threw the alignment off a lot more than I thought. Which was strange, because the car really didn't pull much more or anything, but I saw the tires, and the insides were worn pretty badly. So it will be a new set of Bridgestone RE760's for me this week, and a new alignment as soon as I can within the week or so. I wasn't expecting it to cost me as much as it did, but what can you do, gotta have safe rubber.
I think I'll be going back to 215/45/18 because the load rating for the 225's with the 760 is only 91. I don't mind though, since the car is 90% highway driven, and I don't autoX or anything, and I'm starting to drive a little more on the mild side anyway, so I won't be pushing the limits of these very often at all. They're supposed to be a good tire, and with a new proper alignment I should be happy. I'm thinking about having it set up a little more suited to highway driving, maybe something like -0.8* camber in the front and rear, and a very small amount of toe in at the rear? (I'll go back and read up in the "Alignment In Spec Not Good Enough thread)
