yeahh i hit 60k about a week ago and i bought my car used about 6 months ago and it has always had vibrations on light accel. and decel i bought new goodyear eagles today and that vibration is gone.. i looked at one of my old tires and i must have been so REALLY stupid girl driving it before me because there was a 4" flat spot half way acoross the rear tire.. NO TREAD AT ALL i have never slammed on my brakes that hard i think it would have to been on the freeway to get a patch off of a tire that deep.. anyway it is Very nice not to have vertcies on my tires anymore. AUDI IS ONE SMOOTH CAR WHEN YOU HAVE A ROUND WHEEL
