I had the same problem (car pulling to the side). I just got brand new tires also. What was the problem? Wheel alignment was terrible. I bought some bfgoodrich geforce ta kdw 3 months ago and now their almost bald. Got a wheel alignment and now its fixed now. I made a really bad mistake and waited to long to get a wheel alignment and now im out of $280 bucks for those tires. Get it checked out asap trust me. i wont make that same mistake again.
