Rim size 2013 vs 2016 edge
 

My mother has a 2013 Edge SEL with 20 inch rims. She is in the process of buying a 2016. The 2016 only comes with 18" wheels now. She has Winters for her 2013 with 20 inch rims. The sales lady told her that the ones from the 2013 won't fit, and she has to purchase new ones.

Does anyone know if there is any truth to that, doesn't seem right to me. I can see if the rim size was smaller, but I don't see why they shouldn't work.

They have next to no miles on them and it would be a waste of money to upgrade if you didn't have to.
