Ok fellas sorry for the long post.. I just got back from Big 10 tire today to get my rims and tires and walked out without them more confused than ever... Maybe you all can help. Asked the salesman about rims and tires , he informed me that there were only 2 types of 18" rims that will fit on the 04 F-150, one being the eagle 186 series. He kept mentioning the limited availability of 18x9 6 on 135 mm.... This totally confused me what is he talking about??? I am wanting the 325x60x18 grapplers and i know i have seen these tires on several different rims on some of your trucks, did you have to change to a different size rim or did you stay with 18".. If someone can please tell me the exact and all the deminsion i need for a 18" rim in order for me to fit the grapplers on my truck so i can go in and tell the salesman this is what i want, or do i go with another rim size grrrrrrr!!!!

 

There are more 20-22 inch rims with a 6 lug 135mm than 18" rims.
