I got a good deal on a set of chrome momo wheels. They are 18x8 with a +50mm offset. I've read that they wouldn't fit without using spacers so it doesn't hit the strut. I installed one of the rims to find out that they do fit. Only one problem, between the inside edge of the wheel and the strut is only about 8mm. Is this enough space to run 225/40/18 or do I need to use wheel spacers? Any help will be appreciated. Thanks guys.
