Currently on my CCW SP500's I'm running a BFG KDW in 275/35/18 on an 18x10" wheel up front and BFG DR's in 315/35/18 on an 18X11" wheel out back. Honestly I'm not 110% on the way the tire's sit on the wheels, the fronts are a tiny bit too narrow and the rears a tiny bit too wide for my taste, obviously wheel measurements vary between manufacturers as do tire measurements which could cause my distaste...

I'm thinking of selling my tires (less than 500 miles on them) and switching to Nitto 555's up front in 285/35/18 and Nitto DR's in 305/35/18 out back. I think these two sizes may fit the wheels better and exactly how I'd like, but am wondering if the 285 & 305 in the same aspect ratio could possibly pose a problem with the ABS or anything like that?

Here are the overall diameters of each tire from both manufacturer's websites:
BFG KDW 275/35/18 - 25.6"
BFG DR 315/30/18 - 25.6"

Nitto 555 285/35/18 - 25.95"
Nitto 555DR 305/35/18 - 26.42"

So If I run the Nitto's, I'll have a .47" taller tire out back, is that enough of a difference front to back to cause any problems or be noticeable at all?

Here's a few pics of an SOM WS6 running my same wheels and the Nitto's mentioned above:
(Sorry for using the pics, but whoever's car this is...it looks GREAT!)

Should be fine. I run a .4" diff front to rear on my SS. 275/35ZR18 and 295/35ZR18

Nice, I was thinking that it would be ok
Can you notice the difference in height on yours by looking at them?
From the pics of that SOM WS6 which I posted it doesn't seem that you can tell at all

are you guys running those wheels with no issues like rubbing or anything of that type?

It is negligable, and I really don't notice it . . . but remember it is less than a 1/4" on the sidewall hieght. The OD on my tires front is 25.7 " and rear is 26.1"

FRONT:


REAR:


To answer 02LS1WS6 questions:

With the major aggressive offests I have, the front tire does make minor contact with the plastic wheel well liner at full turn, and the rear, I did have to roll my quarter panel lips, you can somewhat see the slight roll in the picture above.

Yup, even though it's a total difference of .47" in diameter, you're only seeing 1/2 of that on the top and bottom.

The 285's should clear up front just fine, correct?

BTW Xsta, Your car is gorgeous!

For the 315's in the rear I did bang the inside fenderwhel in a tiny bit and also rolled the inside of the fender for some peace of mind...but, that's also because the BFG DR's which I'm running tend to run very wide compared to other tires

Should be fine, especially since Nittos do tend to run a bit on the narrow side. Maybe a little rubbing on the black plastic liner at full turn like me, but I know people running 275/40ZR18 (which I do not like the look of) with no issues.

There is a pic of the rubbing in my album.

Why thank you!
