How about a set of 18" rims off of a Titan?
I can use the same adapter for the bolt pattern.
I found a local guy who is getting rid of his 265/70/18's snows off his Titan.

18" should clear the brake calipers right?
Will the 265/70/18 be OK in the wheel well for a 2009 X??

Does the 2008 Titan have wheel sensors?
