Buying OEM 19s ... couple questions
 

So I think I found of OEM 19s that I'm want to purchase. The only thing is I have an 04x and was wondering if the tires they already have on them would be ok... The rims are 05 and the tires are 45 40 19 rear and 225 40 19 front. Is that gonna work with the X? And I won't need any spacers since they're infiniti wheels or am an idiot for thinking that?

From what I've read, they are close enough in size not to upset the AWD. Spacers = no, you will be flush! You should really consider a drop with those, though. Look in the "Calling all X's with lowered suspension" sticky.
