Car pulling to the left and right
 

Hi, I recently put on new tires for my 2014 mustang. After that my car started pulling to the left a lot and I thought I needed an alignment. I brought my car into the dealership and gotten an alignment, but it was still pulling to the left and sometimes to the right. Any thoughts on what’s wrong?

Have you checked to see if you have a brake caliper hanging up?

I know tires can cause this issue as well. Did this seem to start after the tire change? You said they were new tires. Is that brand spanking new, or new to you? I would have a tire shop look at your tires. Could have some kind of tread separation or other issue going on.

Is the car following ruts and irregularities in the road? If so, that is called "tramlining" and it can be an issue with sticky tires; especially the ones with a solid center rib.

It is due to physics -- if the tires can push hard on the road, then the road can push hard on the tires. I guess the tread design has something to do with it.

If the tires were the only change then I'm guessing this is probably it; or the tires could be defective.
