Thanks all for the info, they are brand new tires and rims. They were balanced at Shelby racing in Vegas so i take it they know how to do it right. I had 17 inch on her before and was getting the same vibs. So i cant blame it on these older style tires plus i love the look of 15 inch with the billboards. I will get a alignment and have them check the balance and everything else around the wheels. It might just be me, but i feel it should not shake so bad.
