Yesterday i switched my winter wheels to my summer wheels. After the installation, my car was pulling towards the left a little. My alignment was in spec before the switched. I lifted the car, pulled the lugs off, switched, lugs back on, and lower the car.

winter tires are stock wheels with 225/55/17 AWD
summer wheels are g37s 19s with 245/40/19 All around
tires filled all the 35psi. lugs all tighten to 80lb/ft

Anyone who changes their own wheels for the summer ever have this problem? Any advice on what could of changed my alignment?

 

That's strange, I would go get the alignment checked. If it's in spec you have some other issues to deal with

 

I'd ask what "in spec" means, because with the narrower tires a small out-of-spec deviation will magnify with the wider tires. And while you're at it, make sure your rear toe is on point! Here's my alignment records, if you want to compare. The "old" column resulted in severe tire wear in the rear, and the March column is wearing a LOT better.
