3" lift and 265x75r16
 

Will I clear P265x75r16 with a 3" lift without trimming anyting also I am going to get new wheels what backspacing will I need

i have 236/75/15 on mine and i had about a 1-2 more of a gap when i had a 3'' lift on mine.

a 3'' lift you should be able to fit a 31''/10.5 under there, i would look into a 16/8 as for back spacing 1.5'' should be what you need, i know i need a 1'' back spaceing b/c my tire rubs the tie rod end.

its all ways good to trim you finders even know you dont want or need to. you never know what your tries are going to grab and hold and bring around next to the finder.

hope that helps.
