If your car is mpfi, check TPS and IAC valve. These are the only two responsible for idle issues.
You have selected the wrong size ! Only thing you can do is bend the wheel arches and make it flat from inside. I had done the same when I was using 155/70 R12. This will not solve the issue completely, but give a try. Let me now if you need pic's.
