I'm running on custom made kinesis k58 wheels with 18x10+73. 285 tires has no problem of rubbing;however,will needed to roll the fenders if you lower and running on a normal alignment . I'm currently mounting 265 tires on 18x10 wheels and I don't see any strectch at all.In fact,It was originally recommend by Kinesis.

Go with 285/30ZR18. Then u'll have a perfect 25" OD, same as stock. Also 285 is perfect on a 10" rim. In fact that's the width that they're measured at and the OE sizing for porsche's. That's why my 285/30/18 SO2A's have Porsche N-3 designation. and I have it on a 9.5" rim with no problems

A 285 tire on a 10" +68 offset will rub. Even on a +73 offset, a 285 tire rubs if the car is lowered.
If you want the freedom to lower your car without doing fender work or running out-of-spec camber (both of which were important to me) run a 275 tire or smaller. A 275/35/18 is ~.3" bigger in overall diameter which means your car will sit a little over a tenth of an inch higher than stock. You won't notice the difference in day to day driving.
Quite simply:
285 tire will have a clearance issues on a +63 offset 10" wheel.
275 tire will be ~.1" to tall.
265 will be stretched and might not fulfill the look you're going for.
If you're running wheels and tires like this, it's for looks. The wheels on my car are simply for looks. They're jewelry. In my opinion, the 275 is the best compromise between looks and fit.

I would suggest going with 265/35, which was suggested by Riley for these wheels, when lowered, and to never worry about rubbing.

265/35/18 is 11" width and will fit on your 18x10" wheels.
Trust me,I know what the Hell I'm talking about?BECAUSE I'M ONE OF THE RARE OWNERS OF THIS SET UP . Or you call Jim from TIRERACK.
285/30/18 is too big for NA S2000. Due to Micky Mouse Torque. LOL

you guys must be on crack when looking at some of your numbers......just go to one of the many tire size calculators out there and compare
Here's a link if you need..... Tire Size Calculator
There are lots of factors to consider before you make a blanket statement that something is to big(with regards to power)....for instance 285/30/18 will give better gearing than the 265/35/18....that may infact allow the car to accelerate faster regardless of the extra couple pounds of rubber
considering they don't make a 265/30/18 or a 275/30/18, it looks like the 285/30/18 will be your best bet(for the speedo and odometer) if you can get it to fit....the 265/35/18 is about 0.6" taller than stock. A 245/35/18 would work if your rim width was just a little smaller.
good luck with your decision and here's some of the comparison info from the website i gave...
