    Im looking at some 17" wheels with 0 offset and 4.75" back spacing. After reviewing some threads, it looks like the magic number is 4.5" to achieve minimal rubbing, so is 4.75" too much?

    It will depend on the type of tire. A heavy tall tread will be tougher than say a Nitto Grappler with a lower tread design.

    4.75 would be too much and would likely rub. Most people who have 285s with 4.5" BS still have to trim plastic and some have to chop the body mount.

    Also, just checking to make sure you have a 3" lift as well. No hope of fitting those tires without one.

    the 4.5" BS is to clear the stock UCAs w/ 285's. the less amount of BS causes the wheel to stick out further and cause more flare rubbing issues. i've got these 315s on 4" BS wheels...CRAZY rubbing that had to be trimmed.
