I was on the interstate last nigt to go to a friends house and I noticed that once I hit like 70, my car starts to pull. But its not normal pulling, its just random, not always the same way pulling. I just got new tires on the back and moved my old ones to the fron so I think that might be the problem. But im not sure. Its like its REALLY hard to controll my car sometimes. It will just randomly start to pull and when i correct it will sometimes pull the other way and make me overcorrect. Its kinda dangerous sometimes.
