I ordered my 18x9s with a 25mm offset that should have the exact same clearance from the control arm as my stock 18s. 44mm offset on a 7.5" just under 6". I didnt bother measuring how much further inboard I could go but I think that 35mm could be pretty close. you made the right choice with the 18mm

 

The biggest that will fit. It bfg your are referencubg an all terain tire?

 

Ok i got one more question. I just ordered the rims and now im thinking tires. either the 285/65/18 or the 295/70/18. i really like the 295's but im not a big fan of trimming plastic. However, if the 285's wont look right im not opposed to the others. If i get the 295 will i have to trim? what will it do to gas milage compared to 285? thanks again fellas!
