I had a set of 17" take offs but when I got there they were the crome steel and not the aluminum. Well now I am looking at a set of 18" KMC's with a LT285/60/18. I like the stock ride of my truck and would rather trim than raise the front end. I think the rims are -12mm offset. Can anyone advise if these would fit without too many problems? Also if anyone has a pics of the same size wheel on their profile that would be great. Thanks in advance.
