Will it work? Anyone have this combo? Pics? Thanks! I know a guy has 225/40-18 on 8.5's and he has no rubbing issues, the sidewall on the 35's are 1/10 smaller... So there is more room between the fender/spring perch. But what about fender space?

I acctually have a similar question, just with a 17x9 rim

Some people like a lil more tire. Some people like a lil less tire. I prefer a lil less, and it just happens to be the correct size for my cav.

9" wide is too wide for our cars
Thats what the guy from Mackin Industries said.
"Ok. From what I can research. Your car requires a 17x8.0 5x100 +35 offset.
You can purchase the Advan Racing in 17x8.0 5x100 +35. They make that size.
If you want 17x9.0 5x114 with a 15mm Kics conversion spacer, I cannot guarantee that it will fit.

Can anyone answer my question?

Our cars are made to run 225/40-18 tires and rims no wider than 8.5....7.5 with a 42mm off set is actaully as close to stock and speedo numbers as you can get...pretty sure anyway!
Here is the info from Tire Rack....I'd say your rim is too small (width wise) and the side wall is not short to run these tires/rims.
Taking the formulas below and dividing all the right stuff I'd say ou need a 9.5 inch rim (width) and you'll end up rubbing the fenders/inside of strut mounts and with a rubber band on there, you'll have one heck of a rough ride!
Also...your speedo will be off quit a bit!
Section Width
Following the letter(s) that identify the type of vehicle and/or type of service for which the tire was designed, the three-digit numeric portion identifies the tire's "Section Width" (cross section) in millimeters.
P225/50R16 91S
The 225 indicates this tire is 225 millimeters across from the widest point of its outer sidewall to the widest point of its inner sidewall when mounted and measured on a specified width wheel. This measurement is also referred to as the tire's section width. Because many people think of measurements in inches, the 225mm can be converted to inches by dividing the section width in millimeters by 25.4 (the number of millimeters per inch).
225mm / 25.4 = 8.86"
Sidewall Aspect Ratio
Typically following the three digits identifying the tire's Section Width in millimeters is a two-digit number that identifies the tire's profile or aspect ratio.
P225/50R16 91S
The 50 indicates that this tire size's sidewall height (from rim to tread) is 50% of its section width. The measurement is the tire's section height, and also referred to as the tire's series, profile or aspect ratio. The higher the number, the taller the sidewall; the lower the number, the lower the sidewall. We know that this tire size's section width is 225mm and that its section height is 50% of 225mm. By converting the 225mm to inches (225 / 25.4 = 8.86") and multiplying it by 50% (.50) we confirm that this tire size results in a tire section height of 4.43". If this tire were a P225/70R16 size, our calculation would confirm that the size would result in a section height of 6.20", approximately a 1.8-inch taller sidewall.
Hope that helped....
Eh...old man with a Corvette now...it was bound to happen sooner rather than later right?
Wow, that means he wants a tire that is about 9.6 inches wide! Of course so do I.
