Thanks KaiserApparently not, as long as the winter wheels you're mounting have fairly modern TPMS sensors in them. Kias will just learn the four new ones, based on what I've read.
It'll be a treat compared to the many years of winter wheel mounting that I did on my Subarus. A little piece of electrician's tape covered the dash light up just fine, but it felt so archaic.
I have 18" Mags that are the same specs as my 20s. Going to use the 18" tire size that matches the car. I always drop a width for snows so 235 60 R18 are a good fit. Still working out the TPMS stuff I do not trust the dealer that they are the only ones.Have you decided if you are running 20's or downsizing to save cost? I'm looking at 17's but will likely end up with 18's, just trying to find reasonably priced non-steel rims so it still looks fairly nice.
