Re: Did I choose the right tire?

If your truck is stock ride height then the 255/70's will fill the fender wells better. Lowered trucks look better with the 275/60's, IMO. The 275/60's also will increase your rpm's at highway speed as compared to the 255/70's if you're running a 373 or higher rear end ratio. If you're running a 3.07 rear end either size will be fine.
