will they fit??

i just installed the bilstein 5100s in the front with a readylift 1” in the rear. i have tires that are 275/65/18 but i have oem nightshade wheels (+25mm offset) so i’m worried about hitting my UCA’s. should i buy 1” or 1.5” spacers to bring them out to about a 0 offset or will they fit without? i only have the one set of wheels with the new tires being just bare rubbers, so i gotta know if i should pull the trigger on spacers before i try get them mounted.

 

3/4" is the minimum width bolt on spacer that I know of (would move it out -19mm, so a +6 on your wheels). Check the 275 width threads to see what the minimum amount of additional UCA spacing is needed for +25mm wheels.
After clear turning around the UCAs, additional wheel negative offset or spacer width is a matter of clearing cab mount at full lock turn, then the pinch weld under compression, then the bottom fender edges if you go way out negative.
