If i decide to go with a 255 which i'm considering do i go for a 255/40 or 255/45. I don't want any effect on my speedometer accuracy so will running anything other than the stock size affect it?

I REALLY want a 275 but i'm still a little concerned about bulge and safety issues if there are any. It's a daily driver for me and commute freeways weekly to school and back. Any recommendations on the best route to go would be appreciated, thanks.

By the way, where in CA are you at?

I decided to run a 255 for the rear just to play it safe and not have much bulge. Question now is do i run a 255/40 or 255/45? I'm guessing a 255/45 just to keep the same sidewall height as my front just have a wider tire for the rears. Any input?
