Shimmy shimmy shake
But one of the rules of vehicle repair is to try free stuff before getting a mechanic involved. So I made sure the tires were correctly inflated. They were a little low, so I pumped them up to Chevy's recommended 50 PSI in the front, 80 PSI in the back. I didn't really notice a change.
Okay, the next free thing would be having all the tires rebalanced and rotated at the chain where I bought them—Big O. That solved about 95% of the problem. No more shake and only a hint of shimmy.
Another reason I went to Big O was that I thought the tires were out of round or maybe even starting to come apart. I didn't have Michelin-level funds when I needed tires, so I had to settle for their cheap house-brand tires, made in China. If it had turned out the tires were defective I could've waved my warranty at them. But that wasn't necessary. At least not yet.
If your vehicle is suffering from the shakes, here's a good article covering the possible reasons. May the causes be simple and the solutions free.
