This is going to be a little long:
I recently purchased 18x9s wheels for my 2001 GT, and when I put on the front wheels/tires (245 40 18's) the steering vibrates between 40-60 mph. I put back on my original rims and of course no shake. SO, I put on one new wheel/tire with an original and still got the shake. I switched sides, and and still a shake. While changing the wheels, I noticed the new rim(s) did not fit "snug". EXAMPLE: When I put on the old rim it fits right over the hub and I don't have to hold it on to put on the lugs, The new rim requires me to hold the wheel in place to put on the lugs. The manufacturer says that these are a direct fit. Does anyone have any suggestions?
