Default Width of tyre vs rim

Hey guys i picked up a couple of 17x7.5" rims with the thought of getting some ET streets for my BF F6. Initially i was looking for 275/40/17s but after a bit of googling it doesn't seem like a 7.5" rim will be wide enough to support that.
So question one, will it work or will it be unsafe or what?
Question 2, I also have my standard 18x8 bf f6 rims so i could go for a 265/40/18 ET street, but sacrificing width and paying more would i be better off finding a pair of 17s to run the 275s or what?
My car has 350rwkw and i haven't taken it to the strip yet, i will run on street tyres first just to see what its got but my aim is to take it to the 10s on ET streets.
Cheers

i'd go for the 275, would be better going at least a 9'' wheel, provides more tyre contact and more stable at high speeds.
