Here is what is happening...I put on my friends Roja rims on my tC just temporarly for a car show and the car shakes when I hit 60 mph. Does anybody know the reason for this? I do not know when the last time he balanced the tires so that could be a factor. Also, those rims were previously on a 96 dodge neon and I'm thinking the camber is different than the tC so it worn down the tires differently than the tC would. I need help and Im a little concerned. The rims are going to be on there for 2 weeks and with this shaking, could it case any long term damage? Any advice would be awesome

 

check the inside of the tire (carefully), the radial belt might be exposed. The tire could be worn down too much on the inside causing it to be unstable at higher speeds. The only realy danger of this is getting a blow out. If this is so...get new tires

 

I'm thinking wheel balance too, myself.

One of the tires might have thrown a belt too.

 

could be missing the hub spacer and a Bad Balanced wheel!!......My bet its unbalanced!
