I just got some New Tires for my car and it seems like it "Fish" Tails, But people told me it is because of my alighment. But do I really need to get an alighment ?? If i do have get an alighment should i get the life-time alighment from firestone or just pay $60-$100 for an alighemnt once. ?? Please help me i want to get it fixed a.s.a.p.

P.S.: I drove my car with new tires for like 150miles will my tires get messed up quick ??

 

what kind of tires you bought. How much is the cold air pressure in the tires.
Low quality tire will affect the handling, so does air pressure. Assuming the tires is the only change to the car, you don't need alignement.
