Hi guys

I apologize if they has been asked a million times before. I have researched and found many different answers.

I own a 2007 g35 coupe. Its time to put some new rubber on it. What is the largest size tire that will fit on the 19 inch rays? I am still using the stock michelin potenzas and looking for something a little thicker. Is anything else required (spacer, etc)

Thanks

 

How think do you want to go? Are we talking more then 255?

 

I was thinking 275/285. Is that overkill?

 

it is...you can run 275's in the rear but they'll poke ugly...get some 255's max 35 on the sidewall

 

Im running 255 on the rear. They fit perfectly, but I wouldn't go any wider. They have a slight poke, but nothing crazy.

 

Yeah i wouldnt go more then 255 on your car unless your going to do some fender work

 

I run a 245/35/19 front and 255/40/19 rear.

After a lot of research on my end, that seemed to be the widest acceptable tire on the stock rims. Tire manufactures do not recommend mounting anything wider than a 255 on the stock 8.5" rear rim.

 

 

Incorrect.

275/35 is a common upsize per Kumho and Goodyear. As well as having no basis in reality... Forza 4 has it as an upsize for their G35 ingame.

If you do go 275, there IS slight bulging. Nothing ugly, but something to research and get used to.

I had to get used to the stretch of the 245 rubber I had on there, and hated it.

Edit: Quick pics from parking lot at work just now. Also, you don't need to roll fenders unless you add spacers too. We're so far tucked that 275's don't rub without.

 

+1 good advice. I think a 255 35 19 for the rear looks great. Just have to consider the % change in the rolling radius and adjust your speedometer accordingly.

 

yeah whats going on there Potenzas are definitively Bridgestones not Michelin.

 

I also have 255 40 19 on the rears of my stock rays and the lip of the wheel in sunken into the tire a bit ill post a picture later on today

 

 

I'm in the same place. I am looking at new tires and wondering the same thing. I run events with my car at NASA AZ and was told by a Z guy that works for Infiniti that he had 245/35 F
275/35 R
on his Z with 19" wheels. He said he had no issues. I'm not versed enough to know if the Z can accept wider tires or not.

I am currently looking for these sizes in Hankook V12's.

 

I think 245/40 fronts would look better with 275/35 rears.
