1999 Buick Lesabre Tires

I have the tires for about 1 month. They rode rough,vibrated a lot and made my steering wheel shake. I had my tires balanced 4 times to correct the problem. The problem persisted for about 2 weeks after the last balance. The ride finally smoothed out. The vibration calmed down and the ride was comfortable. I looked up the problem and seems some tires have to driven a while to get them to break in. I will keep checking and otherwise, I will update my comments 09/05/2021
