Tire Size, Max. tire size for 7x17 / 1.6" drop? Options

[3TST]

I want to know what's the largest tire size that I can go to, without rubbing or bottoming, under the following conditions:
- 7x17 Rims;
- 1.6" drop front and rear.

I previously run Hankook Ventus 205x40x17's (dia. 596mm/23.46").
(Original tire size was 195x65x14 (dia. 609mm/23.98")).
I'm more interested in increasing the profile.
I'm looking at:
- 205x45x17 (dia. +6mm/0.28")
- 215x45x17 (dia. +16mm/0.64")
- 225x45x17 (dia. +25mm/0.99").

So, ultimately the question is:
Can I go to 225 on a 7" rim with a 45 profile w/o rubbing?

Yer Bryan, that's my main concern.
If I go to 225 + with the 1.6" drop will the tire clear the wheel arch.
Especially under heavy cornering, braking, ...

I know that you can go to 225x45x16 but it's that extra 1".

I'd prefer to go for 225x45x17 but my safest bet would be 215x45x17.

I just want to be absolutely sure before spending out c$800 on tires.
(That's for 225x45x17 Michelin Sport tires, they're c$200 a tire here, then there's valves, balancing, fitting,...).
