Hankook RS3 wheel shimmy
I just had a set of 275/35/18 RS3s mounted on a new set of 18x10 Arc8s and noticed a pretty bad wheel shimmy above 45 mph going to the track yesterday. I thought it was a balancing issue, so I ran to a tire shop and got it rebalanced and was off by an ounce on the front tires each, but the shimmy was still there. Still continued the day not pushing to hard and seemed fine. My stock wheels/tires don't have any shimmy, so don't think its an alignment issue.
Any one else experience this or have any thoughts?
