Default Highway Grooves Cause Sway

I have an 06 GS300 that slightly sways when driving on concrete highways that have been grooved. Any suggestions on what causes this or how to correct?

What tires did you have and what did you change too?

i believe that was yoko avs sport. all tires i had after that (so3, perelli pzero nero, michelin pilot sport a/s, dunlop leman 702) they are all good

keep in mind this is on my 98 gs400 with 19" or 20" wheels.

I have Michelin Pilots have tried to adjust PSI, had alignment. Still get fishtail like shimmy on grooved freeways. Any other thoughts?

I have the Michelin Sport. Do you think that could be the problem?

When I was running the S03's on stock wheels, I noticed the same thing. Maybe because they were a really square tire? But after I got the 19s with Toyo T1R have not noticed it since, although I have new suspension also.

They are PS2. I'm talked with the tire shop and they're going to trade for the A/S. Can't be worse, this car is moving side to side like a pin ball machine.

America's Tires installed the Michellin Sport A/S today and they are awesome! Thanks for the suggestion. The Southern California freeways that caused the swerving are the I-10 between the I-15 and 605 also the 210 Freeway from Rancho Cucumonga to Arcadia both directions. But the A/S tires stopped the swerving.
