Hello. I’m currently ending my lease. I have a 21 model with 19 inch wheels. My car is basically in the middle between the 24 preferred and premium. I had a deal worked out for the preferred and they were going to put my Hakkapilita (sp) snow tires back on for the remaining two months of slick weather. That’s when I found out about the preferred having 17 wheels. So the two concerns are having to buy new snow tires for next year (I still have half life on the thousand dollar Haks), and the different ride on the 17s and 19s. Any thoughts? Thanks
