Stock 18's - 285 rear

I want to go with 285's in the read, on a stock 18's.

Stock 4 door, does anyone have experience with anything over 265 in the rear on stocks? im wondering if it will look wrong, or maybe handle improperly. Id have to go with 265 in the front im assuming, or at least 255.

Need tires BADLY, and im interested in a fatter tire on the rear.

Thanks in advance

Yes but it will be shorter than stock, which means your speedometer will read higher than before by about 2% and you will record more miles on your car

I have RE-11's on the OEM 19" wheels (I know a bit different than you're asking about with 18's): 255 F / 285 R. I also have the GC conversion kit that allows for some camber adjustability but feel pretty confident that even without it, this setup would work fine without rubbing.

Maybe i should go 275 this time around. Im not to concerned about the speedometer being 1-2mph off, its the rubbing and fitment issues.

What do you opinionate on the front tires?

I put used 265 tires on both 8.5 inch front wheels once, in an emergency (comes 245 OEM)....the car felt somewhat unstable during that time. It's possible that the effects would be fairly similar if you put a 285 on a 9.5, though I do not have definitive proof.

Just had some of the new Michelin Super Sports put on the rear of my ZCP wheels. The car is lowered on Eibach springs, and I had 295/30/19's installed.

At first I thought I might get some rubbing, but so far (400km) no rubbing at all, and I live in the Gold Coast hinterland, which has some rather rough sections of road.

Not sure what you can fit in the front yet, but it seems like 295's on ZCP wheels work

Good luck

sounds like i should be ok going with at least 275 in the rear, and either stay stock or go 255 in the front.

Any other experiences - please share

Thanks again for the quick replies.

I was planning to on a 265/275 or 265/285 combo as well, but will likely pass.

As mentioned the fronts are only 8.5 and 265s and are not recommended for that wheel width.

Also if you run 255/35 and a 275/35 or something of the like, the overall diameter is about .75" less for both the front and rear. That would mean a larger gap from tire to wheel well, so if you're not lowered, it might look unsightly.

That's why most people would run 255/40 and 275/40 on 18" wheels. Many are running 255/35 and 275/35 on 19" wheels without any issues.

XL is for tires rated to handle extra weight (vs. non-XL tires). I believe that our stock tires are XL rated thus you should stick with XL tires.

Awesome, thank you very much for your input guys.


Gonna go with a 255/40/18, and 275/40/18...

Now to find a tire, i had ps2's on my old g35 - thats the last time i had those. Im not interested in the cost, might go with the stock michelin's again. wish they had the pilot sports in that size =(

Tire research time!

From the pics from the link above, the 255/35 and 275/35 look okay.

I think the sidewall on a 275/40 would bug me. At first I thought the sidewalls on the stock sizes were pretty meaty as is, but I guess I got used to it.

I think I might consider 255/40 and 265/40. The 255/40 would fill in the wheel well a bit more, the sidewall wouldn't be too huge and it would be closer to a square setup. Would also consider a 265s all around, but not sure about a 265 on a 8.5" wheel.
