I have a 2010 lx with 16" wheels. I was given some Konig Slr 17" rims. Do I need to get spacers and what else might I need?

 

In no particular order:

1. Is the lug bolt pattern the same?
2. What's the offset of the stock wheels vs. the new ones?
3. Find yourself some hubcentric rings that'll fit your car and the new wheels.

Have you tried them on yet to make sure they fit properly and clear the suspension and brakes, as well as the fender?

 

^^Exactly.

Find the offset, hub size, lug pattern and make sure it matches your OEM set-up. Lug pattern is easy to check since you will know immediately whether or not you can mount the wheels onto the car.
