Fender flares and tire size
 

Hello i am new to the 240z. What tire size would look good with wide zg fender flares?

There is 100s of different wheel size/look combos for these cars on the market. I would suggest honestly using google for 240z flares, you can see hundreds and hundreds of different setups, from suspension and car height, wheel sizes/styles, etc. Find the car that appeals to you the most and look up their setup. "Look good" is in the eye of the beholder. Good luck!
