aftermarket wheels on 2001 AC - negative 8mm offset too far out?

Hi,
potentially driving to look at/buy a set of wheels for my tundra. They are Black Pacers with E rated terra grapplers. seems like a decent deal at $450, but wondering how much a negative 8 offset will push the tires out. I know because of math they'll push out just shy of an inch, just wondering if anybody has done this on theirs and what their experience is. Will I need to wash the truck every time I hit a puddle?

The truck has a tiny bit of rubbing at full turn when I hit a bump, so moving the tire out a bit wouldn't hurt. 1.5" lift in front and about level in back with 265/70/17 +15 offset currently, new wheels would be 265/75/16 -8 offset. Opinions on wheel size as well?
Thanks
Luke

 

You’ll be alright, what’s the width on the wheels? 8? 9?

 

oohhh I don't know that one. Probably right in that range. looking around though, it looks like pacer only makes a 16x8 in that size.
