I've had oversize tires, sticking out wheels on the truck since 40k and it's got 120k now. Any my stock bearings haven't made even a peep or growl. BJ's are a common thing on these trucks anyway. By 70k the stock uncranked ones are already toast.
In summary: extra wear will be minimal.
Then again..... we really got NOTHING to work with. Haven't a clue what these wheels are tires are going on....don't know your truck year, model, drivetrain....etc...blahblah. Please create a signature to help us HELP YOU!!
