Actually, my wife and I were driving in my truck to my DD's place of work to watch the eclipse with her. She made a comment that the truck was vibrating a lot (and how that made her feel but that is R rated). And it was. The General Grabber tires have been floppy, noisy POS's since I bought them 40k miles ago. I just got used to it so stopped noticing. I had it on my todo list to rotate them but just ordered a new set of Michelin Defender LTX MS2's from Costco instead. I've had the LTX MS2's before and really liked them. Although maybe I should keep the Grabbers based on what she said in the truck.
