245/45/17's are 25.7" in diameter

275/35/18's are 25.6" in diameter

The new tires are actually shorter than the old ones by .1"

thank you.. I usually have to explain this one.. its not that hard to go to www.tirerack.com , pick a tire.. go to specs.. and see the overall diamter, but for the 3 years i've been on this forum it still causes confusion.

They better not be 245/40-17.

Looks like an H&R Supersport drop to me. There's less rubber on the side now, plus the wider rims don't sit as far inside the fender as stock 17x8's do. You're just being paranoid, nothing has changed.
