How is the ride on 18's compared to 17's?? I have heard it makes a big difference. I have stock rims now, but have been looking at 17's, but it seems hard to find 17's with a big enough off set, 18's seem to have the right off set most of the time.
This is a perfect thread for me, the wheels and tires you just got and put on is exactly what i wanted to do, and yes, looks too high.....

When I had nice new 255's and my SC, no traction until 4th gear. So there came the Fikse's, 295's (255 up front), now time for a clutch, x-pipe.........

Drifting
255/40/17 are ~21.016" tall
275/40/17 are ~21.331" tall
So there is really only ~5/16" difference in height, not all that noticeable. But the perimeter of the tire, 66.02" to 67.01" throws off your speed-o.
At the track on my 225/45/17's and 255/40/17's I run about 38psi cold to get the least amount of roll over on the tire, though I still get to the arrow tips so I know I'm using the whole tire.
On the street I run them at 35psi and have very even wear across the tire.
Go figure.
