vehicle pull when on freeway

[Ab9000]

Within the last few weeks my 2008 yaris hatchback had been been getting progressively worse as far as handling goes when on freeways. When on the freeway it would feel like it was going to roll over whenever i needed to turn the car even slightly to the right. Going up or down hills seemed to be worse. It got so bad the other night i had to get off the freeway and take side streets.

I took it to an auto shop(firestone) to get it looked it. I figured it might be my shocks/struts. The shocks/struts were okay. They said it needed tires and an alignment.

well i got it back the other day and its still handling very poorly and the traction feels really bad. It's doing the exact same thing. When the freeway veers to the right and i feel like I need to turn right slightly the traction is really bad and it feels like i'm gonna tip over

i hope i'm explaining the problem well enough. The new tires they put on are champion fuel fighter BL 185/60R15
