depends on what youre getting at. the truck will ride fine and all. maybe create a little drag going down the road from wind hitting it which really wont matter (just saying). the big thing is what your state has for rules. a lot of states want a fender over the whole tire so debree isnt thrown everywhere so you may need to get a fender flare. Massachusetts isnt too picky on that subject for an inch but i know states like Virginia and california are pretty harsh.
also to add, i did the spacer cause im using stock wheels that i painted and wanted to offset them more. i never checked to see what wheels youre using.
