What size 18 is correct and the overbest size for a 4th gen?
18x7.5, 18x8, 18.8.5 ?? Need advise !

 

wider is better

18x8 is more common than 18x8.5 and 18x7.5 is ooooookkk but I would never buy an 18x7.5 on the Maxima

 

I have 18x8.5 with 235/40/18 tires... but.... I havn't put them on yet =\.. just got the maxima waiting for an alarm.. anyone in here have that same setup?? There ADR Sterlings +35mm offset with a 5x114 bolt pattern... Sorry if I went a little offtopic just trying to get almost the same info as you :P

 

yeah.. always go bigger (wider).. i got the 18x7.5 just b/c they were on sale for 50 a piece lesser than the 18x8.. should have spend the 200 to get the 18x8... just my .02
