I found a rim & tire combo on ebay and I was wondering if they would work. They are 18x8 - 225/40/zr18 for the front and 20x8 or 20x9 - 245 or 255/35/zr20 for the rears. Would these be ok or should I go with the 18x8's in all four corners.

Yes that combo will work. I would go bigger on the front tire. 245/40 on the front will look better and as far as the rear I would go with the 255/35/20.

I have 18 inch Irocs all around on my Z and I went with a 245/40/18 on the front and a 255/45/18 on the rear.

 

Does anybody have this setup? Has anybody seen any pics of a 3rd gen with 18's in the front & 20's in the rear?
