Need a lil Help

This is my first post so let me start by introducing myself, My name is Matt i drive a 2008 Acces cab superwhite trd sport. I love tacomas and this site has been very helpful. I have a question and any help will be greatly appreciated. Im sure this may have been asked /answered before but I have a 6 inch pro comp lift and am currently running 18 inch wheels and 35x12.5 tires... but i have spacers... is ther ans offset/backspaciing combo i can run with an 18 inch wheel and a 295/70 tire and ditch the spacers...and have minimul rubbing.. my truck rubs a small amount at full lock in reverse now...just planning on new wheels and tires and would like to get rid of spacers due to it being hard on the bearings. sorry for being so long and thanks in advance

 

1inch.. my wheel now has almost no backspacing.. the wheel im running is a mamba m1...and the wheel has not much of a lip at all almost has a "stock" look to it

 

Thanks
