Hopefully someone else can chime in before going with it as I am sure those TD in 7.5 have an et+45 so I dont think it will be a problem, best to be safe it will clear.
235/40R17 is a better fit, but will need trimming as well and is probably too wide for a 7.5" wide wheel. 215/40R17 is the safest bet unless you're ready to do some grinding.
In terms of width, I'm running 17x8 ET45 (9" total width) with 12.5mm spacers on the front and have 1/2" between the inside wheel rim and my ST coilovers and similar clearance on the outside with 2.5? of camber. No problems on the rear.
All of the above depends upon on the specific tire, but heights are pretty uniforms across tire brands.
