Wheel fitment on 91 ED Civic

[ThEbLaCk]

Hello All,

My friend is selling me a 15" mag wheel with offset of 25. The tyre profile is 20555R15. After I put it on I have a few questions.

1. I used a set of correct wheel nuts provided by my friend but during fitment it appeared that I could only secure the nuts to the threads less than half way in. Is this a problem in terms of safety (ie would the wheel come off when I am driving?).

2. I am assuming because of the extreme offset, the rear wheels are sitting outside the sidewall. In another word, the wheels stick out visibly. Would this be a problem? what is the risk?

3. I have not put all wheels on for test drive. Does anyone have experience or can imagine how would the car would perform in terms of handling? I am not expecting better handling but would it be a big compromise?

Thanks

Randall
