My stock 255/65 General tires are beginning to separate in the sidewall. I need new tires soon! I hate the small tires and want to go bigger. Does anybody have any experience recalibrating their speedometer? Or, are all of you 2001 SE owners driving around with a jacked up reading on your speedometer?

I'm thinking either 265/70's or 265/75's? I know mud flaps will need trimming. Is that all?
