if you go to www.1010tires.com and click on "technical" then "tire calculator" you can compare the tires - specifically the diameters.
The 285 30 20 are less than a half inch bigger in diameter than the 275 40 18's. Many people on this forum maintain that you SHOULD keep a diameter difference on aprox 1 inch ( close to stock) between front and back to avoid POSSIBLE problems with TC and active handling.
Some people ( including me) don't think you need that big a difference.
I'm running 265/40/18 fronts and 285/40/18's rear with no problems.
If you want to err on the side of caution go with the 35's -- they maintain a diameter difference closer to stock.
Or, better yet, go play with the tire calculator and see what set up you think would work best for you.

Diameters aside, your set-up will look goofy because the front tires will have more rubber visible due to their greater sidewall height. This is true for either of your choices. Of course, that may not bother you at all. What sre the widths of your wheels?

The wheels i purchased are 18\9.5 front and 20\10.5 rear EVO 775 chrome.
wcc sells these wheels for a whole lot more than i paid for them and they recomend 265\275\35\18 front and 275\285\30\20 rears so the the stock size on my car are 245\45\17 front and 275\40\18 rear so i want to run 275\40\18 front and 275\35\20 rears so that makes the rears 0.91 biger than the fronts so will it work and not mess up the TC on my car.
Thanks Randy

I just bought a set of Evo Rims as well 18 x 9.5 and 20 x 10.5 and I am going with the 265 35 18 in the front and 285 30 20 in the rear. Going with a 275 in the front will be ok just wider but if you do a 275 in the rear the tire is going to bulg on the sides and the side walls will curve in towards the tred. I have a Z06 and the rear rim is 10.5 and it rruns a 295 so by putting a 275 on the 10.5 Evo is taking it down 2 sizes. I wish I could get a 295 30 20 but like you said 285 is the biggest for the rim as far as I know.

I ended up going with the BFG G force T/A KDW same sizes as you except 265 on the front instead of 275. I have heard some good things about them but will wait and see. Will try and post some pics when I get them mounted.
