When I bought my 2018 WRX (used) it had a set of winter tires. Drove and handled fine, no pull and all seemed to be aligned. I used those for a little over a month before I bought a summer set of wheels and tires. 18x9.5 +38 with a 255/35. The wheels and tires were shipped mounted but not balanced so I brought it to a local shop for balancing. They threw them on the car for me while it was there. As soon as I left I noticed the car was pulling to the right. I brought it back a day later for an alignment. Got it back yesterday and it's still pulling to the right. I checked the tire pressure and it's all good. What else should I be looking for that would cause a aligned car to still pull to one side?
