Upgrading my rims - HELP
 

I have a g35 2007 sedan with the Original 17x7.5 rims +45mm offset; they got messy and I would like to change them. I have a person selling me a set of original Infiniti rims from a QX60. They are 18x8 rims +50mm. I do not know much about measurements, and I would like to know if they will fit correctly on my g35 (especially because front offset difference). I also understand I will have to purchase smaller tires.

I am attaching my g35 rims and the QX60 rims pics.

thank you

I don't think you'll have any problems, but only one way to find out
