What about a 285 or 295? Mathematically, it would fit with a diffrenet sidewall (I think). Anyone else try it? I too am interested.

umm.. have you done it yet? what are the results? also will I be able to tell a notiable diffrence between 275 and 285 or even 295? and do you think anything more then 275 in the front will rub? I take it thats why you are not going any bigger in the front?

You can go 285s all the way around without any rubbing issues. Personally if I was in your shoes I'd go 285s because a 275/35-18 tire is actually about .1" shorter then stock size. 285/35-18 is about .2" taller then stock.

Okay, I have another question about tire size. I want to replace my wheels and tires on my 02 WS.6. I was thinking of 17x9.5 275's in the front,(same as stock), but going with 17x11 315ZR35 in the rear. Will this work without any modification to the wells? <img border="0" alt="[burn out]" title="" src="graemlins/gr_burnout.gif" />

So 285 would be the same size as long as the aspect ratio did not change.

I was referring to the height differences of the 2 sizes.
A 285/35-18 tire would be about .3" taller than a 275/35-18 tire. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

By math, 295/35-18 results in:
26.13" height... 0.48" taller than stock.
82.09" circumference... 1.52" more than stock.

These measurements result in your speedometer and odometer reading LOW by 1.85%
Not too bad...
When your speedometer reads 54mph, you're actually going 55mph. When it reads 108mph, you're actually going 110mph.
And for every 1000 miles traveled, your odometer will show 981.47 miles.

For future reference, here's a helpful link to get all this data:

I would also recommend looking up the actual tire measurements from the manufacturer, because cut sizes of different brands do vary.
i.e. a 315/35-17 Nitto is cut smaller than a 315/35-17 Yokohama.
