i have a set of 4th gen offset wheels with a 2 inch spacer and i was looking to use a 255/35/18 up front...will that **** anything off or am i in the clear...i am stock right height atm.....i plan on a 1.5 inch drop in the near future

 

Should be fine. A 245 50 16 is 25.6 inches tall, the 255 35 18 is 25.0 tall. A 265 35 18 is 25.3 tall. How wide is the wheel? If its a 9-9.5 inch wheel the 255 prolly wont fit it very well.

 

8.5 inch wheel

 

That should work fine assuming the backspacing and everything works out. I cant guarantee it because I've never tried it. But it should work.
