Largest tire size on a stock wheel

Largest tire size on a stock wheel
Tomorrow my 04' S2000 will be at the Tire Rack getting a new set of Kuhmo MXs mounted on the stock wheels.
I need to know the largest tire size i can mount onto the 04' stock wheels by tomorrow morning.
I heard you can fit 275s on the rear and 245s on the front with no problem. When i called the tire rack today, the guy on the phone couldnt tell me how large i could go. He also stated the fenders might have to be rolled in order to fit something as large as a 275.
If you change the wheel offset, will that allow a larger tire size to fit?
Sorry but the search returned nothing useful and i need some quick help!

245 & 275 are too large for the stock 17" wheels. Looking at the MX specs on the Tire Rack website show that the recommended wheel size for the 245 is 7.5-9.5" depending on which tire, and the recommended wheel size for the 275 is 9-11".
Here's a link to the spec page for the MXs: http://www.tirerack.com/tires/Spec.jsp?mak...&model=ECSTA+MX
*I couldn't put a direct link in this post for some reason*

Seems like the largest you can probably go is 265/40-17 as per:

Keep in mind by using the 265 mm tire, you will be going slightly faster then what your speedometer reads... 61.5 mph actual vs. 60 mph displayed as per:

The wheel width recommendations are just recommendations. A half inch isn't going to make a difference. It's not optimal, but it'll still work. Many stock autocross class ITR guys are running 225 Hoosiers on a 6" rim. Those tires are practically the same width as 245s, and Hoosier recommends a 7-9" rim.
More importantly, why do you need to put the biggest tire? Are you going to track it or autocross competitively? If so then no matter how wide, a street tire is not going to cut it. You're much better off with a separate set of wheels and tires to use on those days.
If you're primarily using them on the street, there are too many drawbacks to using that big of a tire. First a bigger tire is going to be a heavier tire. That will negatively affect acceleration. Second, a taller tire is going to change your final drive. That will also negatively affect acceleration. Third, the speedo will be off. That is fixable if you get a yellow box though.
The best thing to get is a tire that will keep the car's handling balance. The extra 0.04g of grip you _might_ get from a wider tire means nothing if you screw up the car's handling. Not to mention the noise cheaper tires can make. How far can you test the car's limits on the street when they're squeeling like pigs?
The stock RE050s are brilliant tires. If they weren't so bloody expensive I wouldn't use anything else.
