Stock 2005 wheels and other rims with smaller backspacing

[2005 wrangler X ?]

ive read and as you all point out dont believe all you read and see

my original rims 15x7 5.5 BS STEEL

rims ive taken off

Mickey Thompson ALUMINUM
MT-058
15x8J
ET-28

IF i use the MT-058 with the decreased backspacing (they hang way out there compared to the stock rims)
will the rims cause MORE wear to the axles and bearings?

thank you

Technically... probably so. Will you ever see a problem, doubtful.
