canadiandodge.... as been said, the spacers wont hurt anything more than a wider wheel will, but just for refrence, my 9in wide wheels have a 0 offset (directly in the middle) and my 12.5's clear the frame but just barley, i do jut a VERY small rub on the frame, but only at full lock to the left and only when going straight, the frame is the only part other than the fender that will rub, but remember the further you push the tire out, the more interfearence you will have with the fender/innerfender and front bumper, i still had to trim a piece off my innerfender to get them to clear

 

u do have a 4x4, and if u ever go off road on the beach theres a good chance u'll snap those lugs on the spacers. it's not like having a bigger/wider rim its like have longer lugs w/ wasers. y chance stressin anything
i think the only good use for these spacers are to put nice rims on a 2wd truck

 

i am thinking i might have to say no to them then and just get wider tires i have a plus 12 offset so wouldnt know how muhc of a spacer to get so i am just gonna leave it how it is lol
