I have e87 2008 116i and I have 205/55/16 7Jx16 ET40 rims on it.
Can I fit e90 rims to my car if could not find a e87 rims on it. I want to change to 17 or 18 inch rims and wider tires like 225/45/17. Can I fit it without any problem or changing?

The tire sizes you listed are almost the same in diameter. That is a good thing. The issue on width would be the problem. As you go wider you remove clearance for turns and suspension motion. That makes it hard to say "yes that will fit" because it depends on the width of the rim you use, the backspacing, steering angles and ride height.

7.5Jx17 ET43 with 225/45/17 is it okay if I find original second hand e87 rims to my car's recommended sizes?

That should work fine as the factory already has designed the rims to fit your car. What usually happens is that people will order an aftermarket rim from a company without looking at the information above and end up with tire scrub or even damage the car because they are not correctly sized. However, if you use a factory rim in the "optional" tire size you are 99% of the time okay. That 1% is if the car is modified with a body kit or lowered and now the optional tires do not fit. So if you bought a 17" rim that was optional it should be fine.

Easy way to tell if you might have problems is to turn the steering wheel tight against the locks and look at how much room is around the various parts. Have a couple friends push down on the bumpers to check the clearance then as well.
