I recently purchased new tires for my Camry. Michelin Primacy MX4. It’s one of the highest rated passenger tires on tirerack.com. After driving the car on the freeway, it tends to “track” with the grooves on certain sections of the freeway. It feels like the car is wobbling. So I went back to Costco where I bought the tires, and they said it is completely normal and eventually it will go away as the tires wear down. Considering this the first time I bought Michelin tires, I was a little skeptical. So, a week later I had to buy some new tires for my Supra, so I bought some Michelin PS2’s and the same “tracking” occurs on that section of the freeway. However, the tracking is not as bad as in the Camry, but I can definitely feel it. In the past I have always purchases angled grooved tire tread designs (Toyo T1-S, Toyo T1-R), and I never felt this “wobble” on the freeway. Both Michelin tires have a straight tread design. Keep in mind, my alignment is perfect, the balancing of the tires are perfect. Has anyone experienced this? I live in SoCal.
