255/75/17 on stockers???

Alright so I'm thinking of ditching my 265/65/18 terras and going back to stockers with some bfg mud terrains 255/75/17. Question is will it work with no rubbing??? My tires on 18s rubbed a little until I shaved some of my front mud flaps off, but I think it may have been due to the 4.5" bs. I'm thinking the new tires might be tucked in just enough and be skinny enough not to rub... Current tires are 31.54 x 10.7 and the new ones will be 32x10.

Stock suspension, but was thinking of picking up a set of cheap 1.25" leveling blocks for the front just in case i do need it. Then once I see how it looks I could maybe get some billys later. In the event I do need to raise it should I just set the billys on 1.75 or leave them on 0 and get some springs too? Recommendations?? Also really wanting an arb bumper if that makes a difference on what to do as far a shocks and springs. Thanks!
