Last August I bought a 2017 Forte5 SX which I love driving every day in the SF south bay area. My family lives up in Reno, NV and I typically drive up there for the Christmas holidays. During the winter season there are snow patrols near Donner Pass and other points where they will not let you proceed without snow chains. The KIA handbook says not to use snow chains under any circumstances on the 18" tires that came as standard equipment on the car. Can I get 16 inch wheels with snow tires to use on winter trips that will not void the KIA warranty if I have to use tire chains? All ideas and possibilities will be appreciated! Oh, I'm new here, so please forgive me, if this has been covered before!
