3" lift question about tire size and UCA rubbing.

I have a 3" toytec Boss lift kit on the way, with Light Racing UCAs. I would like to run a 285/70/17 tire on stock rims. Will I be able to run these tires without adding wheel spacers, or will I rub on the light racing UCAs?

 

You'll need wheel spacers, the tires will most likely rub on the spindles.

 

Thanks, do you think 1" spacers will be enough?

 

I'm not 100% positive but 1" should be fine. When I had 285's mounted on my 17x9 wheels with 4.5" backspace I could just slide my hand between the tire & spindle. So if the stock wheels have 5.5" backspace now a 1" spacer would make it 4.5" & in theory it should be ok. I don't know the specs on the stock wheels.
