Message The stock rear wheels on a TT are 16x8.5+35 and if you put them on the front they fill out the wheel well very well without rubbing (with a 245/45ZR16).

Your rear wheel is the same offset as a stock rear wheel but is an 1" wider. So the wheel face will be about 17mm farther out than stock. I would have gone with a larger offset on the rear. And a 275 on the rear.

Here's my math:
Stock 8.5" wheel is 216mm wide. Divide by two and the centerline of the wheel sits 108mm off the face of the wheel. Subtract the positive offset (+35mm) and the mounting point of the wheel sits 73 mm from the face.
For a 8.5" wheel with +30 offset, the mounting point sits 78mm off the face. So on the front you should be ok (depends on spoke thickness).
On the rear you have 9.5" wheel which is 242mm. Centerline of the wheel sits 121mm from the face of the wheel. With a +35mm offset the mounting point sits 86mm from the face of the wheel. So the face of the new rear wheel should be 13mm farther out than stock. That's a half inch or so. You're pushing it on the rear.
