I recently switched to all season tires from winter tires and noticed the steering was a bit off. Nothing too drastic but the car would slowly veer off to the right so had to steer in the other direction to correct even on a straight road. I checked the air on all tires and they were low so filled them up and that did the trick. My guess is that some tires had less air than others which made it never when driving. All for a cost of $1
