19x9.5" +30 all round with dunlop sp sportmaxx 245/35/19 all round. So Metal_Slinger they're same as 350z rears, you should be fine to fit your 350z set but might need different tyre sizes (more an issue with profile height).
Will be going wider tyres soon hopefully (bought them used with the current ones) aiming for 255/30/19 fronts & 265/30/19 rears. Current ones are also slightly to tall.
