Summer tires that don't tramline

[fan_aLba]

I Recently picked up a set of all season 195/55-15 HANKOOK VENTUS V2 CONCEPT 2. The tires tramline like crazy on the highway pulling to the groves on Socal freeways. I have heard that a solid center rib ( like this tire has ) can cause this on freeways with groves which they all have in la.

I had the car aligned when i got the tires and after ( with some toe in within spec and it changed nothing ) i just purchased this 08 yaris the car is stock, but i do have another yaris so i am familiar with how the car feels.

So i am looking for a new set of tires and i wanna stick with a summer tire or sporty all season in the same size. Anyone have experience with a set of summer tires that don't tramline on this car ?
