New wheel/tire question

[ToyotaDan]

I bought some new wheels and tires through a tirerack. I also bought spacers because I thought I need them. I just need some help. This is for a 2003 4runner. Current setup is:

Old wheels are 30mm off set - 5.5" back spacing.

My new wheels have a 10 mm offset and 4.88 inch back spacing.

The old tires were 265/70/17 - new tires are 285/70/17

Will the new wheel/tire combo fit without rubbing my UCA? The car has a 3 inch revtek lift. Currently I am about 1/2 inch away from the UCA. I am trying to avoid using wheel spacers if possible.

Thanks!!

You may have more clearance on the new wheels, check this offset calculator. Do a test fit with one of the new wheels.

What about back spacing? Does that effect anything?

The lesser offset means your backspacing is less.
